Chapter 10: Crazy Black

"Don't interrupt!" Wu Jinling said, "Let me ask you, the light we see 100 million light years away is actually the light from 100 million years ago, right?" ”

"Yes, that's right!" Su Yu nodded.

"Good! So here's the problem. Let's say you're flying at 3 million kilometers per second in a Sky Battleship that's 10 times the speed of light.

So, when you reach this light, are you coming to the light of 100 million years ago? Wu Jinling asked, but before Su Yu could answer, she replied, "No, you came to the bright light at that time, and you won't go back to the past at all." You're still in the present! ”

Su Yu nodded and said, "I understand, I see." But if you fly faster than the speed of light, really nothing strange will happen? ”

"Yes!" Wu Jinling said: "But it takes a long distance to do it!" ”

"How?" Su Yu's interest was aroused again.

"Let's use this light as a metaphor!" Wu Jinling said, "We are now 100 million light years away, and what we see is the light of 100 million years ago. If we stand still, we will have to wait 100 million years to see the light we have now!

However, if we were to travel at the speed of light, it would only take 50 million years to see the light we have now. If we were traveling faster than the speed of light, then it would take less time.

In other words, if it used to take a year to see, under the condition of superluminal speed, it may only take one day to see! If there is a tree on the light (hypothetically), it will bloom from ūn day, bear fruit in summer, fall leaves, and wither in winter! It would have taken a year, but in your eyes, the process is 365 times faster. In other words, the speed of time in your eyes has accelerated, and you can see the entire season in one day! In a minute, you can see the process of a flower from blooming to wilting!

Of course, it's not that the flow of time has really become faster, but that what you see in your eyes has accelerated! It's like using stunts to show the process of blooming on a computer screen in less than a minute! I see? ”

"Ah, I see!" Su Yu said with emotion.

"Of course, the stranger is yet to come!" Wu Jinling said with a smile.

"What else is so strange?" Su Yu had already vaguely guessed what Wu Jinling was going to say next, but he still cooperated.

"As you get closer to the light, you see it in real time. Then, you exceed the light and continue to fly forward.

At this time, when you look back, what will you see? ”

Su Yu pondered for a moment and said, "When I look back, what I see is the bright present, but as I fly forward, I will gradually see the bright past!"

In other words, I will watch everything I saw before. Only this time the order is reversed, from the present to the past. Well, I'll see that one flower wither, and then gradually come back to life, and then see her bloom, and finally see the branch gradually shrink into a seedling, until it becomes a seed, and then before there is no seed!

It's like stepping back in time! I understand" Su Yu jumped up suddenly, and then slammed into the top of the multi-day battleship. (In weightlessness, a little force can make people fly)

Wu Jinling walked over, gently touched the top of Su Yu's head, and chuckled: "Little fool, it hurts." Now you can see, it's not that time is really turned back, it's just that you see some images. If you measure it by time, time is still moving forward, and the light will also change, but your speed is too fast, and you can't see his future anymore. When you look back, all you can see is the distant past. The longer you fly, the longer you can see the past until you can't see it anymore. ”

Su Yu smiled and said, "If my speed is only slightly beyond the speed of light, then the process will take longer than it actually happens, like slowly going backwards when playing a movie."

If I go much faster than the speed of light, the process will accelerate. It's like a quick rewind when a movie is playing, I get it. ”

"Got it, okay. Now that the faster-than-light problem is solved, let's see what's ahead! ”

But suddenly, Wu Jinling's face changed greatly, and he said, "Pressure, why has it become so heavy?" ”

At the same time as Wu Jinling spoke, Su Yu also sensed the sudden appearance of gravity. ,

If on the surface of a star, the absence of gravity is unusual, but in the alien sky, the presence of gravity is unusual.

"Could it be that we passed through a huge celestial body and were therefore affected by its gravitational pull?" Su Yu asked.

"But there's nothing on the instruments of the Sky Destroyer?" Wu Jinling said.

"Is this celestial body invisible?" Su Yu said.

"What celestial bodies are invisible?" Wu Jinling frowned and said, "It's not good, black."

The two of them were talking, and the pressure became heavier.

Wu Jinling hurriedly put on the helmet and beckoned Su Yu to put on the helmet as well, and the two of them fixed their bodies on the seats, and at the same time turned on the observation function of the Sky Conquering Battleship.

At the very front of the battleship, the brightest light still flickered.

However, the pressure from the Sky Raiders is growing. Wu Jinling and Su Yu's consciousness collided, and they reached a consensus in an instant, and at the same time issued an order.

The Sky Raider instantly turned around one hundred and eighty degrees and turned around and flew back.

Although I don't know if there is any danger, the two of them are now seriously injured and have not recovered, so it is better to be cautious.

It wasn't until the two of them could no longer feel that kind of pressure that the two of them stopped the Sky Capture Battleship and stopped in the starry sky.

"The attraction just now is very strange, we have to be careful," Wu Jinling said, "It is very likely to be an invisible black."

Su Yu nodded, turned on all the detection equipment of the Sky Conquering Battleship, and began to monitor the battleship in all directions of 360 degrees.

Suddenly, Su Yu exclaimed in surprise and pointed to a space in front of the battleship. There was a shiny ring the size of a turntable spinning rapidly.

In the center of the ring, it was pitch black, and there was nothing.

"What's that? Is it black? Su Yu asked.

Wu Jinling also saw the ring, and she said softly: "It's hard to say, shouldn't black be invisible to anything, why is there a shining ring rotating outside?" ”

As the two spoke, the shape of a star next to the ring suddenly changed.

Next to the ring, there is an equally shining blue-star.

Su Yu understood that this blue star was actually a star that was brighter and more dazzling than the sun.

A star is like a block of iron, it turns red when heated, and if it is heated again, when the temperature rises, it turns orange

As the temperature gradually rises, the color of the iron will gradually change to yellow, white, blue, and white until blue

Theoretically, all stars are a mass of gas, but there will be a violent nuclear fusion reaction inside the gas, causing the star to glow and heat.

Although the Sun is also a star, it is only a yellow-star...... It is more than a grade different from the blue-star in front of him, both in terms of temperature and volume.

This blue-star is much brighter than the Sun and much larger than the Sun.

However, just now, there was no such blue star here, nor did it have that shining halo.

It's as if they suddenly appear somewhere, and come out in the blink of an eye.

Su Yu and Wu Jinling also deliberately called up the previous observation video, in fact, at the previous moment, there was indeed nothing anywhere.

"Strange?" Su Yu said in a low voice and looked at the blue star again. At this time, Su Yu found that the shape of the blue-star had changed again. It resembles the sun and looks like a disc-shaped star.

But now, the blue-star began to protrude shallowly against a part of the ring, as if a tumor had grown on its surface.

Gradually, the shape of the entire blue star changed, and instead of being a circle, it became a pear.

It's just that the pear-shaped tip is facing the shiny ring!

"It's Hei Wu Jinling said: "Black is devouring this moment blue-star?" ”

As soon as Wu Jinling's words fell, Blue-Star slammed a thin line at the tip of the shining ring.

Then, with a bang, a large mass of matter was stripped from the blue star and sucked into the ring at an incredible speed.

Then the whole blue-form began to be torn apart en masse, like a tornado, and quickly threw itself into the ring.

Leaning on a section of the ring, it quickly disintegrates into a thin mist-like substance, which is like smoke into the ring. At one end of the circle in the courtyard, Blue-Star was also constantly separating, and large clouds of smoke burst out of Blue-Star's body and were absorbed.

Soon, the blue-star transformed into a thin line, all of which entered the inner part of the ring. ,

But the ring was still spinning brightly, and the circle formed by the outermost part of the ring did not grow a single point in size or shrink a point. But the inside of the ring thinned out obviously.

If measured by time on Earth, then the total time taken by black to swallow blue stars is 56 seconds!

Not even a minute!

It was now established that in the center of the ring was a large black ring, though the ring appeared to be the size of a millstone. But don't forget that a blue-star, much larger than the Sun, is only the size of a plate, and I don't know how much smaller than a ring.

"It's incredible!" Su Yu sighed.

"Yes, the power of black is beyond imagination!" Wu Jinling also sighed.

"But what is that glittering circle?"

"Plasma bar!" Wu Jinling said, "There is a science fiction book, and that's how it is told.

When black devours stars, the substances it absorbs are so hot that they all turn into plasma. (A mixture of completely ionized atoms and free electrons.) ）

As this plasma moves towards the black spiral, the velocity gradually increases, forming a disk.

At the center of the disk, the isomorphic particles are continuously sucked inward, and are quickly accelerated to near or even beyond the speed of light (depending on the volume and engulfing force of the black).

At the same time, there are some lines that emit from the black edges. At a distance of tens of thousands of miles or so from Hei, the pressure of these lines is enough to counteract Hei's extremely strong gravitational pull.

Therefore, at the edge of the black, the plasma will not be sucked in due to the linear pressure. They form a shiny ring and rotate at a very high speed.

However, the plasma will not be like this forever, as it will be sucked into the center of the ring and then sucked into the black at an even more frantic rate. ”

"How did this black come about?" Su Yu asked.

Wu Jinling shook his head and said, "The darkness is formed by the collapse of stars. When a star collapses to a certain extent, its interior is very dense, even denser than that of a neutron star.

You know, neutron stars are so dense that the matter on them can weigh up to 100 million tons per cubic centimeter! ”

100 million tons per cubic centimeter?

When Su Yu heard this number, the first thought that slipped through his mind was: If there is a copper ore with that density? So doesn't it mean that if I devour a few centimeters of copper ore, I can evolve a copper body?

100 million tonnes is exactly the amount of metal that the gold eater's brain needs to swallow to evolve.

However, Su Yu understands that it is impossible for copper ore to reach such a high density. A neutron star, as the name suggests, is a star that is composed purely of neutrons. On a neutron star, there are no electrons, no protons, and no atoms, so it is impossible to form any metal, at most it can only be regarded as a dense substance.

"However, the density of black is much greater than that of neutron stars. If a star the size of the sun shrunk into a sphere with a diameter of two or three thousand meters, the density would reach tens of billions of tons per cubic centimeter, which is hundreds of times that of a neutron star.

At this time, the gravitational pull on the surface of the star will be so great that even the light cannot escape, and the human eye will not be able to see it, so it will be called black.

Since the gravitational pull of black is very strong, all material near it will be sucked away.

Generally speaking, the larger the star, the more likely it is to form a star as black as the sun, and it is basically difficult to become black! ”

"Ah, it turns out that Hei is just a condensed star, not really a Su Yudao.

"Of course not, and the volume of black is generally not large. The area of the ring you see is proportional to the volume of black.

However, it is strange that the current black area is even larger than that of a star! ”

"It's bigger than a star, so how big must it be before it becomes a star?" Su Yu exclaimed.

"However, the larger the star, the lower the density when it turns black. I just don't know what the density of this black is, if the density is super large, the volume is super large, then the gravitational force is bound to be unimaginably huge! ”

"Isn't it true that if you get sucked in, you can't escape anymore?" Su Yu asked.

"That's pretty much it. In general, the only things that can resist gravity are speed and distance. Even on the black surface, the light can't escape. But if the speed exceeds the speed of light, it is possible to escape. Or, far enough away from the dark, you don't necessarily feel the attraction of the black.

So, if you want to get rid of the black, you have to combine these two points and speed up the escape at a distance of enough from the black. ,

The farther away from the dark, the easier it is to escape. If you are sucked into a black surface, the speed required is insane.

Moreover, I suspect that the gravitational pull on the surface of such a huge black has already exceeded that of ordinary black! It takes less than a minute to devour a blue star, which is an astonishing speed.

Of course, what's even weirder is the way this black appears! It appeared without warning, as if it had been shuttled through space! Fortunately, the place where it just appeared was far away from the Sky Capture Battleship.

Otherwise, if it happens to appear near the Sky Raider! We're just going to be sucked in. Wu Jinling said with palpitations.

Su Yu suddenly let out a surprised sound, it turned out that on the monitoring screen of the central control room, the shining ring had disappeared.

"Be careful," Wu Jinling said, "It's hard to observe the black, but we have other ways to detect it."

Black has a huge gravitational pull that causes the surrounding light to bend and even space to bend. In addition, it will be very hot near the black, and it will also emit high-strength threads. We just need to be careful, and it won't be difficult to detect it.

The only problem is that this black seems to be a black that can move at high speeds and even travel through space, which is a bit of a problem! ”

However, Su Yu didn't seem to hear Wu Jinling's words, his eyes widened, and he stared blankly at the front without moving.

Wu Jinling was taken aback by Su Yu's expression, and hurriedly followed his line of sight. I saw that in front of the Sky Capture Battleship, near that large cloud of light, the dense shining stars around it were rapidly disappearing.

Before they disappear, a shiny disc will appear around them, and then the entire star will burst, surging into black like smoke, but it is not a light smoke, but a hot stream of matter.

As one star disappears, the ring disappears, and when it reappears, it is already in front of another star. No one knew how the black could have such a fast speed, and the distance of hundreds of thousands of light years would teleport over in an instant.

As the stars continued to disappear, the shiny ring quickly grew larger, and it could be seen on the monitoring screen that it was spinning at a frantic rate.

At this time, not far in front of Su Yu and Wu Jinling, a starry sky battleship suddenly appeared!

This is a starry sky battleship that I don't know where it came from, and it looks like it should have been shuttled from some space.

So, did they shuttle here unintentionally, or did they shuttle here purposefully.

Two different choices lead to completely different consequences. If it's unintentional, that's fine. If it came with a purpose, then is there any inevitable connection between this starry sky battleship and this crazy black?

"Not good" Wu Jinling said in a lost voice, "That black can accurately appear on the edge of a star every time, and it seems to have its own way of detecting stars, and this star battleship may have something to do with it." Even if there is no connection, the spatial fluctuations caused by its appearance are very easy to attract this black!

Let's run! ”

As soon as Wu Jinling's running word was issued, the sky-seizing battleship rushed out at a speed of 250,000 kilometers per second.

At the moment when he flew away from the place, Su Yu seemed to feel that his body was also heavy, and at the same time, the temperature in the central control room also rose rapidly, almost as hot as a steamer.

However, as the Sky Conquering Battleship was speeding at its speed, the pressure on Su Yu's body became lighter and lighter, and the temperature in the central control room gradually returned to normal.

Su Yu and Wu Jinling saw a terrifying scene in their helmets at the same time, the starry sky battleship behind Su Yu swirled in the air like leaves, and then fell straight into the center of the black ring, and then exploded, turned into nothingness, and disappeared!

However, Su Yu suddenly felt that something was wrong, and just in front of the Sky Conquering Battleship, a huge blue-star suddenly appeared.

In front of this blue-star, everything was overshadowed except for the dazzling light it emitted, it was steaming and bright, but it didn't know where it came from.

Then, right in front of Su Yu's eyes, another starry sky battleship appeared. The speed of this Star Battleship is not fast, it is only about half the speed of the Sky Conquering Battleship.

The moment the Star Battleship appeared, a shining ring appeared in front of Blue-Star. The ring emitted a dazzling light, carrying a huge gravitational pull, and at the same time sucked the starry battleship into it.

The sky-seizing battleship swung its tail one hundred and ten degrees in the air, and directly turned around and flew towards the road it came. ,

Behind the two of them, the star warship that unfortunately fell did not fall immediately like the first one. At the moment it was spinning wildly around something unseen.

After the first lap, it fell a few minutes and was almost on the verge of converging with the shiny plasma.

If it falls into the circle of plasma, this starship will have little chance to fly. At this point, it will soon fall into the invisible blackness.

However, the speed at which it spun suddenly increased considerably. It seems that the airship is starting to use its own power and start to accelerate.

After the second lap, the Starship circled at an even more frantic speed, moving a little further away from the shiny ring.

The speed of the starship increased to almost the speed of light, but the time it took to circle the circle did not complete it in a second.

But the bigger it spins, the faster it spins. It was getting farther and farther away from the black, and at last it suddenly broke away from the black and headed in the direction of the Sky Raider.

"Oh no, I don't know if it will lure the black over and speed away!" Su Yu said. A
