DPM Chapter 39-Big Bang Part 4
Translated by Snowfall77
Mozun could no longer see his own distorted face, no more than he could hear his wailing voice.
His heart had torn apart in an instant. Bits of ice hit his cheeks, and he didn’t realize they were his own tears.
Over and over he flew along the edges, searching for Wu Xingyun. He’d watched Wu Xingyun disappear, and now he wanted to get the soldier back. But Mozun failed. For there was nothing left to find.
No longer able to feel any part of his body, Mozun shouted loudly at the black hole until he was hoarse, his sound failing to transmit.
He didn’t know that Wu Xingyun had spoken to him in that last moment. There’d been no working communicator between the two them, and Wu Xingyun’s lips hadn’t been discernable through the helmet.
Wu Xingyun had said to Mozun: “Let go of me. Run for your own life.”
Then Wu Xingyun had thrown off Mozun’s hand, broken free of the number one enemy who refused to let him go, and fallen into the abyss.
Mozun floated adrift for three days before being found by the Demon Army.
By that time, Mozun was unconscious, his vitality almost faded away.
The two sides declared another war, with the Federation claiming that the Night Shard was dead, and quickly gaining the upper hand.
Wen Nuo, owing to his success in eliminating the dreaded mutant demon and overall battle proficiency, was promoted to the rank of Admiral, vaulted into the highest levels of Federation policy-making.
Wen Nuo’s influence, along with his years of research and tactical improvements, caused the Demon Army to retreat in defeat. The people of the Federation viewed Wen Nuo has a hero, along with Wu Xingyun, the Ghost soldier who’d ambushed and shot the Night Shard. A statue of Wu Xingyun was erected, a Federal monument placed in the public square of the Federation’s main planet.
When Wu Xingyun’s family received the news, they cried horribly. Wen Nuo fulfilled his promise to take good care of Wu Xingyun’s parents and brothers. No matter how busy, every week Wen Nuo would spare time to visit Father and Mother Wu, accompanying them.
Nonetheless, no amount of compensation could make up for Wu Xingyun’s parents’ painful loss of their son. No more than Wen Nuo could assuage the raging guilt in his heart.
After a year, Mozun regained consciousness. His body was badly damaged, weaker than that of an ordinary person, while his fighting spirit appeared destroyed, crippled by an overwhelming depression.
The Alliance withheld the news that he was still alive. On Yuanxing, Wu Xingyun’s escort team was placed under house arrest, not allowed to have any further communication with the Federation.
Every day, as he sat in the place where he and his soldier had lived together, Mozun couldn’t help reminiscing about the first person to move him after more than two thousand years.
Perhaps it had been the best outcome. That kind of person, it would have been impossible for them to be with Mozun. And he, Mozun, lived too long, far too long. It was tedious and tiring.
Living with constant regret, he deplored the way he’d let his emotions affect his decisions at that time, seizing Wu Xingyun and taking the soldier away.
Mozun shouldn’t have stayed at Wu Xingyun’s family home that night, shouldn’t have tested his place in Wu Xingyun’s heart.
And the last and worst regret was that, at the final moment, Mozun shouldn’t have let go of Wu Xingyun’s hand.
“I killed him……” Mozun murmured softly, staring at their original wedding photos.
He refused to approach anyone, staying a man curled up in a corner alone. Victory, defeat, survival, death. As time passed, it all lost its meaning. He wished he had died then. It would have better to have not been found, not saved.
One day, Mozun was at the Yuanxing Federation base, sitting dazed in Wu Xingyun’s old room, when he heard crazy, joyous yelling: “I figured it out! I got the calculations!”
Cocking his head, Mozun stood up and went out the door. There Mozun saw the astronomer Pu Sishuo dancing about, clutching a stack of manuscript paper, with more papers flying out around him.
“I figured it out! I finally know that the mass of a black hole can be linked to a wormhole! Haha! I am the greatest scientist in all of human history!!!” The astronomer had clearly gone insane.
Yet in a split second, Mozun had an even crazier speculation.
Quickly walking over to the astronomer, Mozun tugged on him: “What do your words mean?!”
Pu Sishuo glanced at Mozun with lofty contempt: “With your IQ, how could you understand?! I’m going to find my old friend. Hahaha! My research room’s scientific results of are finally ahead of his!” With that, the batty astronomer gave Mozun a hearty hug and kiss, saying: “I love you! Hahaha, I love this world!”
Next, the astronomer stumbled his way to the physicist’s lab, where the two, who had been good friends, but were currently arch-enemies, began heatedly debating and quarreling.
Three days later, Mozun was finally clear on Pu Sishuo’s latest research.
In the middle of the Tri-Star system, if there was enough nuclear energy provided, in that instant a black hole would form. At the same time, a white hole would also form.
All the matter devoured by the black hole would ejected from a white hole.
In short, during the initial period of the black hole’s formation, a very small amount of the pulled-in material would travel through time and space.
The formerly listless Mozun sped at lightning speed to Wu Xingyun’s residence, in order to investigate a desk drawer.
""
Mozun had never been able to understand how two people could look exactly the same, have the same habits, even similar names.
He’d chalked it up to coincidence, unable to imagine that the man from thousands of years earlier, and present day Wu Xingyun, could ever be the same person.
But when Mozun opened the desk drawer, saw the pen on the stack of paper, and the practiced, crooked characters of Wu Xingyun’s handwriting, in that moment, everything became clear.
Wu Xingyun was not dead. He’d been pulled into a black hole, and instead of being elongated and crushed, he’d been sent back to the end of Earth, over two thousand years ago.
Wu Xingyun was the one who’d brought Mozun out of the last days, the one Mozun had loved with all his heart.
In different times and spaces, different identities, Mozun had fallen in love with the same person twice.
Staring distractedly at the stack of paper, Mozun finally gave way to loud laughter: “He’s not dead! He’s not dead! Turns out neither of them died! He’ll come back, he will come back, remembering everything, he’ll return to my side!”
The sound shook the whole base, even spreading to the other side of the valley.
His previous depression lifted, Mozun suddenly shifted to glowing with life and hope. He ran quickly towards the mutant city, his blood pumping with a passion.
“You two scientists, from now on, any request you’ve got, I’ll meet it! However huge a laboratory you want to build, we’ll make it that big! I have only one request, and that is-calculate when and where Wu Nebula will come back again! Whether it’s ten years, a hundred years, a thousand years, ten thousand years, as long as I’m not dead, I will wait for him!”
The physicist Kinson questioned Mozun’s sanity: “How can you be so sure……A person will be crushed to a speck by a black hole, any matter entering would be destroyed……He can’t be alive.”
Astronomer Pu Sishuo sighed: “Goodness, talking to people with an IQ problem is really tiring……Do you know what a singularity is?”
The two scientists shook their heads in unison: “Moreover, even if he did survive, it was pure luck. There’s no way it’d happen a second time! It’s just not scientific, and we’re the scientists!”
But Mozun’s mouth curled up in a slight smile, his eyes were shining, and he stated categorically: “No! I’m quite sure that person was him! I’m even more sure he’ll come back! He’ll know everything and stand beside me! Forever! It may not be scientific, but……I’m not a scientist!”
From then on, Mozun’s life once again had a goal. He was no longer the hollow, lonely, forever solitary Night Demon. Instead, he firmly believed that one day his thousand-years-old lover would again travel space and time, to be by Mozun’s side as before. They would fight side by side, live together, and there wouldn’t be any more suspicion, deception, or betrayal. The person they’d trusted the most had always been each other.
Mozun stood at the top of Yuanxing’s highest building, gazing down on the whole city. Honeysuckle never sleeps, and the neon lights glimmered in the night.
“When you come back again, I hope, I won’t disappoint you anymore.” Mozun softly murmured. “So, you must come back!”
Thus, two years after his supposed death, the Night Shard miraculously appeared on the front lines of the battlefield. With his return, all the previously lost Alliance territories were promptly recaptured.
The Federation fell into another crisis, everyone believing in the legend of the immortal Devil. While Mozun took the opportunity to accuse the Federation of not keeping its word, and breaking the peace treaty. That led to Wen Nuo being court-martialed, for disregarding the treaty and causing a restart of war. In the end, Wen Nuo became the Federation’s number one war criminal.
On the first day of Wen Nuo’s trial, Shi Fei came to see him.
Both men squatted in the cell, smoking cigarettes together.
Shi Fei said: “I can’t imagine how the Night Shard didn’t die! He’s doing just dandy, and you’re the criminal! This herd of……” Shi Fei closed his mouth before going any further. Over the past few years, he’d finally learned how to curb his temper a bit. Some things shouldn’t be said, so he had to try not to utter them.
Wen Nuo leaned against the window, his gray eyes calm. He took a deep inhale, then unhurriedly puffed out smoke, not answering.
“You go to court tomorrow, you should change your tune!” Shi Fei continued. “The old saying is good, while there’s life, there’s hope. What if you’re exiled, or that bunch of bastards throw you to the Night Shard? It’s too bad!”
Spewing out another smoke ring, Wen Nuo stretched out a slender finger to tap ash off, his tone tranquil: “I’m not going to change my tune. My father, grandfather, great-grandfather, all soldiers, died on the battlefield. I was born to defeat the Night Shard, to eliminate the Demon Army! For this, I can give up everything. I can sacrifice everything.”
“They don’t understand. Peace with the Night Shard is just asking a tiger for its hide. Some things can be abandoned, but some things must be adhered to. I’ll stand my ground during the trial. No renegotiation of peace! We clearly had the upper hand, however we were defeated by the enemy’s psychological tactics. It’s not just ridiculous, it’s a disgrace!”
“Even if I’m exiled, or they chop my head off and give it to the Night Shard, I’m sticking to my point of view.” Wen Nuo’s voice remained indifferent. “If I’m banished to the edge of the galaxy on the spot tomorrow, you don’t have to send me. I think, I……Two years ago, I’d already come to this point.”
“Two years ago?” Shi Fei was a little taken aback, having almost forgotten what had happened two years past. Now he recalled Wen Nuo’s order to detonate a nuclear bomb at Wu Xingyun’s coordinates.
“Yes, that was when I spoke to him for the last time……And I said to you that sacrifice is inevitable in war.” Wen Nuo’s voice still didn’t falter. He quietly gazed out his cell, into the dark corridor and the cell opposite, housing another political prisoner.
“Even though I’ve always felt guilty about it, I’ve never regretted making that decision. If I could go back, I’d still make the same choice,” Wen Nuo said.
Shi Fei, feeling melancholy, didn’t speak.
Wen Nuo stayed silent also, turning to look outside. In his mind, the image of that small soldier appeared, Wu Xingyun’s slightly disappointed, but decisive words echoing in Wen Nuo’s ears: “It doesn’t matter, I don’t blame you.”
“After I leave, please help me take care of Wu Xingyun’s family.” Those were Wen Nuo’s last words to Shi Fei. They would not see each other for a long time to come.
At the same moment, Mozun stood in a distant sea of stars, watching the black hole that had taken Wu Xingyun away.
The black hold had become much larger, constantly devouring the matter around it.
The consumed matter would be pressed to oblivion.
Eternally taking, always growing, until finally, in the distant future, the galaxy, the universe would be swallowed by this black hole. Nothing will exist.
Yet where was Wu Xingyun now? Would he come back? Mozun didn’t know. He couldn’t dare think how small the probability of Wu Xingyun’s return was.
Mozun would only stubbornly believe that his lover would come back. Until the heavens were old, until the universe ceased to be, Mozun would wait and resolutely trust.

White Holes
White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. More recently, however, some theorists have been asking whether these twin vortices of spacetime may be two sides of the same coin.
To a spaceship crew watching from afar, a white hole looks exactly like a black hole. It has mass. It might spin. A ring of dust and gas could gather around the event horizon — the bubble boundary separating the object from the rest of the universe. But if they kept watching, the crew might witness an event impossible for a black hole — a belch. “It’s only in the moment when things come out that you can say, ‘ah, this is a white hole,'” said Carlo Rovelli, a theoretical physicist at the Centre de Physique Théorique in France.
Physicists describe a white hole as a black hole’s “time reversal,” a video of a black hole played backwards, much as a bouncing ball is the time reversal of a falling ball. While a black hole’s event horizon is a sphere of no return, a white hole’s event horizon is a boundary of no admission — space-time’s most exclusive club. No spacecraft will ever reach the region’s edge.
Objects inside a white hole can leave and interact with the outside world, but since nothing can get in, the interior is cut off cut off from the universe’s past: No outside event will ever affect the inside. “Somehow it’s more disturbing to have a singularity in the past that can affect everything in the outside world,” said James Bardeen, a black-hole pioneer and professor emeritus at the University of Washington.
https://www.space.com/white-holes.html
A white hole is a hypothetical feature of the universe. It is considered the opposite of a black hole. As black holes don’t let anything escape from their surface, white holes are eruptions of matter and energy and nothing can get inside them.
White holes are a possible solution to the laws of general relativity. This law implies that if eternal black holes exist in the universe, then a white hole should also exist. It is a time-reversal of a black hole. They are expected to have gravity, so they attract objects, but anything on a collision course with a white hole would never reach it.
Theoretically, if you were to approach a white hole in a spacecraft, you would be inundated by a colossal amount of energy, which would most likely destroy your ship. Even if your spaceship could withstand gamma rays, light itself would start slowing you down like air resistance slowing down a moving vehicle on Earth.
And even if the spaceship is built to be unaffected by the energy emission, space-time would be weirdly warped around a white hole; approaching a white hole would be like going uphill. The acceleration required would get higher and higher while you move less and less. There isn’t enough energy in the universe to get you inside.
Of course, this is fairly counterintuitive. How could energy in a white hole seemingly come from nowhere other than space-time itself? This is one reason why their existence is very unlikely. However, there are some theories in which white holes are possible, but perhaps not quite as described in general relativity.
As they are alleged counterparts of black holes, white holes too would be formed by a gravitational singularity. A singularity is a point-like feature in space-time where the gravitational field becomes infinite. Infinite values in physics are usually an indication of missing pieces in a theory, so it is not surprising that quantum mechanics and relativity struggle to explain the finer details of singularities.

Black Holes
Can we artificially create a black hole?
Sophie Allan from the National Space Centre answers this question for us.
In theory, to make a black hole all we would need to do would be to compress a huge amount of matter and energy into a tiny amount of space. In practical terms, however, this is incredibly difficult.
There is much disagreement about the minimum size a black hole can be, and standard physics offers different answers to more exotic ‘multi-dimensional’ physics.
Einstein said that mass and energy are equivalent – you can turn mass into energy and energy into mass – so very high energy particles smashing together could potentially lead to the creation of a black hole. However, the energy required for this would be the equivalent to taking the mass of a mountain range and converting it into energy. For reference, a nuclear weapon only releases the energy of a few grams worth of matter.
So even the Large Hadron Collider at CERN, with its particles traveling at close to the speed of light will not, under standard physics, be able to create a black hole.

Is it possible to make an artificial black-hole?
Certainly.
All you have to do is bang two large neutron stars together.
We have recently observed such a collision, or rather a merger of two inspiraling neutron stars, although they might not have been quite large enough to form a black hole. LIGO and VIRGO and various observatories across the electromagnetic spectrum from radio to gamma rays made contributions. The result was either a very large neutron star or a very small black hole.
1. The acquisition of the two neutron stars and the organization of such a collision is left as an exercise for the interested student of stellar engineering. Don’t try this at home, or indeed within a light year of home.
2. Likewise the capture of the many Earth masses of gold, platinum, iridium, and other valuable metals produced in the collision.
We do not yet know for sure whether a star of perhaps 50–130 solar masses would be able to collapse and create a black hole, or whether it would shed enough mass to end up as a neutron star, but research on the question continues. We think that smaller stars make neutron stars in core-collapse supernovas, and larger stars explode completely, leaving no remnant, in pair-instability supernovas.

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.[6] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[7][8] The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, according to general relativity it has no locally detectable features.[9] In many ways, a black hole acts like an ideal black body, as it reflects no light.[10][11] Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.
https://en.wikipedia.org/wiki/Black_hole
In short, black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities.. When a star dies, it collapses inward rapidly. As it collapses, the star explodes into a supernova—a catastrophic expulsion of its outer material. The dying star continues to collapse until it becomes a singularity—something consisting of zero volume and infinite density. It is this seemingly impossible contradiction that causes a black hole to form.
The extreme density of the new singularity pulls everything toward it, including space-time. Space-time, in a very basic sense, is the union of space and time as one four-dimensional continuum. So, what happens if you bend it? Well, if you were to experience a black hole up close, time would definitely move much differently from the way it does here on Earth. If you imagine space-time as a suspended flat plane of Silly Putty, then creating a singularity would be like putting a marble in the center. The marble would bend the plane downward dramatically, which would elongate any interaction with the plane toward the marble. The same thing happens with black holes, though the distortion you would experience would be a bit more severe than anything Silly Putty could generate.
At the edge of a black hole, or the event horizon, time begins to slow astronomically. The farther into a black hole you venture, the more distorted time becomes. Some theories even propose that if you could survive the initial entry into a black hole, the inside would produce images of the future and the past all at once—an idea consistent with the multiverse theory of the universe. While this is an interesting concept—and no doubt the origin of many sci-fi favorites—because of the inaccessibility of black holes, there is no known way to test it. What is commonly accepted, however, is that, because of a black hole’s distortion of the space-time continuum, time at the base of its event horizon passes far slower than time on Earth.
Black holes are hard to find, but if you not only did find one but also went inside it, you would discover that it is fatal. The intense gravitational force from the singularity pulls at different rates, depending on location relative to the center, which can produce a “spaghettification” effect on any object unfortunate enough to be caught inside. Just as the word suggests, spaghettification elongates the object in question so that it resembles spaghetti.
We may never be able to prove exactly what happens inside black holes, although many scientists are making the connection between singularities and the big bang theory, which proposes that our universe exploded into existence from what could have been a singularity.
https://www.britannica.com/story/how-do-black-holes-really-work
Gravitational waves emitted by black holes that have ended up on the other side of a wormhole (and possibly in another part of the universe) could prove that wormholes exist — if they actually exist. It’s not too far out, since gravitational waves have previously given away black hole collisions and neutron stars smashing into each other. The way the gravitational wave emission of a black hole changes as the black hole traverses a theoretical wormhole could end up being proof of a phenomenon that, at least for now, only happens in science fiction.

Black holes vs. wormholes
Gravitational-wave observatories have detected more than 20 giant collisions between extraordinarily dense and massive objects such as black holes and neutron stars. However, more exotic objects may theoretically exist, such as wormholes, the collisions of which should also produce gravitational signals that scientists could detect.
Wormholes are tunnels in spacetime that, in theory, can allow travel anywhere in space and time, or even into another universe. Einstein’s theory of general relativity allows for the possibility of wormholes, although whether they really exist is another matter.
In principle, all wormholes are unstable, closing the instant they open. The only way to keep them open and traversable is with an exotic form of matter with so-called “negative mass.” Such exotic matter has bizarre properties, including flying away from a standard gravitational field instead of falling toward it like normal matter. No one knows if such exotic matter actually exists.
https://www.msn.com/en-us/news/technology/what-would-happen-if-a-black-hole-fell-into-a-wormhole/ar-BB17RKMW
Astronomers think they might be able to detect black holes falling into wormholes using ripples in spacetime known as gravitational waves, but only if wormholes actually exist and such a scenario ever happened, a new study finds.
According to Einstein, who first predicted the existence of gravitational waves in 1916, gravity results from the way in which mass warps space and time. When two or more objects move within a gravitational field, they produce gravitational waves that travel at the speed of light, stretching and squeezing space-time along the way.

Speed of Light
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
https://www.space.com/15830-light-speed.html
The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s[Note 3]). It is exact because, by international agreement, a metre is defined as the length of the path travelled by light in vacuum during a time interval of 1⁄299792458 second.[Note 4][3] According to special relativity, c is the upper limit for the speed at which conventional matter and information can travel. Though this speed is most commonly associated with light, it is also the speed at which all massless particles and field perturbations travel in vacuum, including electromagnetic radiation (of which light is a small range in the frequency spectrum) and gravitational waves. Such particles and waves travel at c regardless of the motion of the source or the inertial reference frame of the observer. Particles with nonzero rest mass can approach c, but can never actually reach it, regardless of the frame of reference in which their speed is measured. In the special and general theories of relativity, c interrelates space and time, and also appears in the famous equation of mass–energy equivalence E = mc2.[4]

Astronomer Pu Sishuo sighed: “Goodness, talking to people with an IQ problem is really tiring……Do you know what a singularity is?”
The two scientists shook their heads in unison: “Moreover, even if he did survive, it was pure luck. There’s no way it’d happen a second time! It’s just not scientific, and we’re the scientists!”
But Mozun’s mouth curled up in a slight smile, his eyes were shining, and he stated categorically: “No! I’m quite sure that person was him! I’m even more sure he’ll come back! He’ll know everything and stand beside me! Forever! It may not be scientific, but……I’m not a scientist!”
From then on, Mozun’s life once again had a goal. He was no longer the hollow, lonely, forever solitary Night Demon. Instead, he firmly believed that one day his thousand-years-old lover would again travel space and time, to be by Mozun’s side as before. They would fight side by side, live together, and there wouldn’t be any more suspicion, deception, or betrayal. The person they’d trusted the most had always been each other.
Mozun stood at the top of Yuanxing’s highest building, gazing down on the whole city. Honeysuckle never sleeps, and the neon lights glimmered in the night.
“When you come back again, I hope, I won’t disappoint you anymore.” Mozun softly murmured. “So, you must come back!”
Thus, two years after his supposed death, the Night Shard miraculously appeared on the front lines of the battlefield. With his return, all the previously lost Alliance territories were promptly recaptured.
The Federation fell into another crisis, everyone believing in the legend of the immortal Devil. While Mozun took the opportunity to accuse the Federation of not keeping its word, and breaking the peace treaty. That led to Wen Nuo being court-martialed, for disregarding the treaty and causing a restart of war. In the end, Wen Nuo became the Federation’s number one war criminal.
On the first day of Wen Nuo’s trial, Shi Fei came to see him.
Both men squatted in the cell, smoking cigarettes together.
Shi Fei said: “I can’t imagine how the Night Shard didn’t die! He’s doing just dandy, and you’re the criminal! This herd of……” Shi Fei closed his mouth before going any further. Over the past few years, he’d finally learned how to curb his temper a bit. Some things shouldn’t be said, so he had to try not to utter them.
Wen Nuo leaned against the window, his gray eyes calm. He took a deep inhale, then unhurriedly puffed out smoke, not answering.
“You go to court tomorrow, you should change your tune!” Shi Fei continued. “The old saying is good, while there’s life, there’s hope. What if you’re exiled, or that bunch of bastards throw you to the Night Shard? It’s too bad!”
Spewing out another smoke ring, Wen Nuo stretched out a slender finger to tap ash off, his tone tranquil: “I’m not going to change my tune. My father, grandfather, great-grandfather, all soldiers, died on the battlefield. I was born to defeat the Night Shard, to eliminate the Demon Army! For this, I can give up everything. I can sacrifice everything.”
“They don’t understand. Peace with the Night Shard is just asking a tiger for its hide. Some things can be abandoned, but some things must be adhered to. I’ll stand my ground during the trial. No renegotiation of peace! We clearly had the upper hand, however we were defeated by the enemy’s psychological tactics. It’s not just ridiculous, it’s a disgrace!”
“Even if I’m exiled, or they chop my head off and give it to the Night Shard, I’m sticking to my point of view.” Wen Nuo’s voice remained indifferent. “If I’m banished to the edge of the galaxy on the spot tomorrow, you don’t have to send me. I think, I……Two years ago, I’d already come to this point.”
“Two years ago?” Shi Fei was a little taken aback, having almost forgotten what had happened two years past. Now he recalled Wen Nuo’s order to detonate a nuclear bomb at Wu Xingyun’s coordinates.
“Yes, that was when I spoke to him for the last time……And I said to you that sacrifice is inevitable in war.” Wen Nuo’s voice still didn’t falter. He quietly gazed out his cell, into the dark corridor and the cell opposite, housing another political prisoner.
“Even though I’ve always felt guilty about it, I’ve never regretted making that decision. If I could go back, I’d still make the same choice,” Wen Nuo said.
Shi Fei, feeling melancholy, didn’t speak.
Wen Nuo stayed silent also, turning to look outside. In his mind, the image of that small soldier appeared, Wu Xingyun’s slightly disappointed, but decisive words echoing in Wen Nuo’s ears: “It doesn’t matter, I don’t blame you.”
“After I leave, please help me take care of Wu Xingyun’s family.” Those were Wen Nuo’s last words to Shi Fei. They would not see each other for a long time to come.
At the same moment, Mozun stood in a distant sea of stars, watching the black hole that had taken Wu Xingyun away.
The black hold had become much larger, constantly devouring the matter around it.
The consumed matter would be pressed to oblivion.
Eternally taking, always growing, until finally, in the distant future, the galaxy, the universe would be swallowed by this black hole. Nothing will exist.
Yet where was Wu Xingyun now? Would he come back? Mozun didn’t know. He couldn’t dare think how small the probability of Wu Xingyun’s return was.
Mozun would only stubbornly believe that his lover would come back. Until the heavens were old, until the universe ceased to be, Mozun would wait and resolutely trust.

White Holes
White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes. More recently, however, some theorists have been asking whether these twin vortices of spacetime may be two sides of the same coin.
To a spaceship crew watching from afar, a white hole looks exactly like a black hole. It has mass. It might spin. A ring of dust and gas could gather around the event horizon — the bubble boundary separating the object from the rest of the universe. But if they kept watching, the crew might witness an event impossible for a black hole — a belch. “It’s only in the moment when things come out that you can say, ‘ah, this is a white hole,'” said Carlo Rovelli, a theoretical physicist at the Centre de Physique Théorique in France.
Physicists describe a white hole as a black hole’s “time reversal,” a video of a black hole played backwards, much as a bouncing ball is the time reversal of a falling ball. While a black hole’s event horizon is a sphere of no return, a white hole’s event horizon is a boundary of no admission — space-time’s most exclusive club. No spacecraft will ever reach the region’s edge.
Objects inside a white hole can leave and interact with the outside world, but since nothing can get in, the interior is cut off cut off from the universe’s past: No outside event will ever affect the inside. “Somehow it’s more disturbing to have a singularity in the past that can affect everything in the outside world,” said James Bardeen, a black-hole pioneer and professor emeritus at the University of Washington.

A white hole is a hypothetical feature of the universe. It is considered the opposite of a black hole. As black holes don’t let anything escape from their surface, white holes are eruptions of matter and energy and nothing can get inside them.
White holes are a possible solution to the laws of general relativity. This law implies that if eternal black holes exist in the universe, then a white hole should also exist. It is a time-reversal of a black hole. They are expected to have gravity, so they attract objects, but anything on a collision course with a white hole would never reach it.
Theoretically, if you were to approach a white hole in a spacecraft, you would be inundated by a colossal amount of energy, which would most likely destroy your ship. Even if your spaceship could withstand gamma rays, light itself would start slowing you down like air resistance slowing down a moving vehicle on Earth.
And even if the spaceship is built to be unaffected by the energy emission, space-time would be weirdly warped around a white hole; approaching a white hole would be like going uphill. The acceleration required would get higher and higher while you move less and less. There isn’t enough energy in the universe to get you inside.
Of course, this is fairly counterintuitive. How could energy in a white hole seemingly come from nowhere other than space-time itself? This is one reason why their existence is very unlikely. However, there are some theories in which white holes are possible, but perhaps not quite as described in general relativity.
As they are alleged counterparts of black holes, white holes too would be formed by a gravitational singularity. A singularity is a point-like feature in space-time where the gravitational field becomes infinite. Infinite values in physics are usually an indication of missing pieces in a theory, so it is not surprising that quantum mechanics and relativity struggle to explain the finer details of singularities.

Black Holes
Can we artificially create a black hole?
Sophie Allan from the National Space Centre answers this question for us.
In theory, to make a black hole all we would need to do would be to compress a huge amount of matter and energy into a tiny amount of space. In practical terms, however, this is incredibly difficult.
There is much disagreement about the minimum size a black hole can be, and standard physics offers different answers to more exotic ‘multi-dimensional’ physics.
Einstein said that mass and energy are equivalent – you can turn mass into energy and energy into mass – so very high energy particles smashing together could potentially lead to the creation of a black hole. However, the energy required for this would be the equivalent to taking the mass of a mountain range and converting it into energy. For reference, a nuclear weapon only releases the energy of a few grams worth of matter.
So even the Large Hadron Collider at CERN, with its particles traveling at close to the speed of light will not, under standard physics, be able to create a black hole.

Is it possible to make an artificial black-hole?
Certainly.
All you have to do is bang two large neutron stars together.
We have recently observed such a collision, or rather a merger of two inspiraling neutron stars, although they might not have been quite large enough to form a black hole. LIGO and VIRGO and various observatories across the electromagnetic spectrum from radio to gamma rays made contributions. The result was either a very large neutron star or a very small black hole.
1. The acquisition of the two neutron stars and the organization of such a collision is left as an exercise for the interested student of stellar engineering. Don’t try this at home, or indeed within a light year of home.
2. Likewise the capture of the many Earth masses of gold, platinum, iridium, and other valuable metals produced in the collision.
We do not yet know for sure whether a star of perhaps 50–130 solar masses would be able to collapse and create a black hole, or whether it would shed enough mass to end up as a neutron star, but research on the question continues. We think that smaller stars make neutron stars in core-collapse supernovas, and larger stars explode completely, leaving no remnant, in pair-instability supernovas.

A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it.[6] The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.[7][8] The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, according to general relativity it has no locally detectable features.[9] In many ways, a black hole acts like an ideal black body, as it reflects no light.[10][11] Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

In short, black holes are massive pits of gravity that bend space-time because of their incredibly dense centers, or singularities.. When a star dies, it collapses inward rapidly. As it collapses, the star explodes into a supernova—a catastrophic expulsion of its outer material. The dying star continues to collapse until it becomes a singularity—something consisting of zero volume and infinite density. It is this seemingly impossible contradiction that causes a black hole to form.
The extreme density of the new singularity pulls everything toward it, including space-time. Space-time, in a very basic sense, is the union of space and time as one four-dimensional continuum. So, what happens if you bend it? Well, if you were to experience a black hole up close, time would definitely move much differently from the way it does here on Earth. If you imagine space-time as a suspended flat plane of Silly Putty, then creating a singularity would be like putting a marble in the center. The marble would bend the plane downward dramatically, which would elongate any interaction with the plane toward the marble. The same thing happens with black holes, though the distortion you would experience would be a bit more severe than anything Silly Putty could generate.
At the edge of a black hole, or the event horizon, time begins to slow astronomically. The farther into a black hole you venture, the more distorted time becomes. Some theories even propose that if you could survive the initial entry into a black hole, the inside would produce images of the future and the past all at once—an idea consistent with the multiverse theory of the universe. While this is an interesting concept—and no doubt the origin of many sci-fi favorites—because of the inaccessibility of black holes, there is no known way to test it. What is commonly accepted, however, is that, because of a black hole’s distortion of the space-time continuum, time at the base of its event horizon passes far slower than time on Earth.
Black holes are hard to find, but if you not only did find one but also went inside it, you would discover that it is fatal. The intense gravitational force from the singularity pulls at different rates, depending on location relative to the center, which can produce a “spaghettification” effect on any object unfortunate enough to be caught inside. Just as the word suggests, spaghettification elongates the object in question so that it resembles spaghetti.
We may never be able to prove exactly what happens inside black holes, although many scientists are making the connection between singularities and the big bang theory, which proposes that our universe exploded into existence from what could have been a singularity.

Gravitational waves emitted by black holes that have ended up on the other side of a wormhole (and possibly in another part of the universe) could prove that wormholes exist — if they actually exist. It’s not too far out, since gravitational waves have previously given away black hole collisions and neutron stars smashing into each other. The way the gravitational wave emission of a black hole changes as the black hole traverses a theoretical wormhole could end up being proof of a phenomenon that, at least for now, only happens in science fiction.

Black holes vs. wormholes
Gravitational-wave observatories have detected more than 20 giant collisions between extraordinarily dense and massive objects such as black holes and neutron stars. However, more exotic objects may theoretically exist, such as wormholes, the collisions of which should also produce gravitational signals that scientists could detect.
Wormholes are tunnels in spacetime that, in theory, can allow travel anywhere in space and time, or even into another universe. Einstein’s theory of general relativity allows for the possibility of wormholes, although whether they really exist is another matter.
In principle, all wormholes are unstable, closing the instant they open. The only way to keep them open and traversable is with an exotic form of matter with so-called “negative mass.” Such exotic matter has bizarre properties, including flying away from a standard gravitational field instead of falling toward it like normal matter. No one knows if such exotic matter actually exists.

Astronomers think they might be able to detect black holes falling into wormholes using ripples in spacetime known as gravitational waves, but only if wormholes actually exist and such a scenario ever happened, a new study finds.
According to Einstein, who first predicted the existence of gravitational waves in 1916, gravity results from the way in which mass warps space and time. When two or more objects move within a gravitational field, they produce gravitational waves that travel at the speed of light, stretching and squeezing space-time along the way.

Speed of Light
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
https://www.space.com/15830-light-speed.html
The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s, or 186000 mi/s[Note 3]). It is exact because, by international agreement, a metre is defined as the length of the path travelled by light in vacuum during a time interval of 1⁄299792458 second.[Note 4][3] According to special relativity, c is the upper limit for the speed at which conventional matter and information can travel. Though this speed is most commonly associated with light, it is also the speed at which all massless particles and field perturbations travel in vacuum, including electromagnetic radiation (of which light is a small range in the frequency spectrum) and gravitational waves. Such particles and waves travel at c regardless of the motion of the source or the inertial reference frame of the observer. Particles with nonzero rest mass can approach c, but can never actually reach it, regardless of the frame of reference in which their speed is measured. In the special and general theories of relativity, c interrelates space and time, and also appears in the famous equation of mass–energy equivalence E = mc2.[4]
