The universe is vast and boundless, hiding countless secrets. Ｘ

During this voyage, Yu Yifeng stood in the captain's room, thinking about it in a daze......

Strangely, the curvature engine turned out to be only an L2 level technology, which seems to have become the greatest gift of the universe......

Sailing beyond the speed of light in curvature is not constrained by the theory of relativity and is more energy-efficient than conventional sailing. It is also the curvature that makes it easier to roam from star to star......

Exotic matter, on the other hand, is a special substance used in the curvature engine. As a type of dark matter, it is hidden in space and can be said to be almost ubiquitous.

Strange matter can not only warp space, but when there are enough of it, it can also cause space-time vortices.

Just like a whirlpool in the ocean, which can bring the local water surface closer to the bottom of the water, this kind of space-time vortex can make two local spaces that are relatively far apart get closer to each other in an instant......

That is...... "Wormholes" in science fiction!

Based on this theory, it has been hypothesized that if there is a strange substance called Phantom Matter, because it has both positive energy and negative mass, it can create a repulsive effect to prevent the wormhole from closing.

Therefore, such a "wormhole theory" is also an important research content of the "dark matter" theory.

Using wormholes to travel long distances, in the theory of dark matter, from fantasy to possible.

Unfortunately, the amount of strange matter needed to open a wormhole is far beyond the current capacity of humans.

With the energy level of human beings, they can only open wormholes slightly larger than Planck's length, which is not enough to accommodate a quark.

And in the experiment, it was found that the duration of this ultra-small wormhole is very, very short, exploding into a cluster of particles in a short time of minus 27 seconds of 10.

This phenomenon ...... It is very similar to a miniature black hole, which directly triggers deep thinking among scientists!

People are wondering: what exactly does a "black hole" have to do with a "wormhole"?

Yu Yifeng is very interested in these cutting-edge sciences, and he has been studying since he was free during this time. For any interstellar civilization, of course, the faster it flies, the better...... Wormhole technology is, of course, much higher and more advanced than the curvature engine.

Some scientists believe that wormholes may be able to connect parallel universes with baby universes, providing the possibility of time travel. There are also those who believe that time travel is impossible, and that it is possible to instantly cross a long distance through a wormhole......

Some people also think that the wormhole may be a space-time tunnel connecting a black hole and a white hole, so it is also called a "gray road......

Therefrom...... There is also another black hole science: some kind of black hole with angular momentum is actually a wormhole!

This type of black hole is called a "Kerr black hole". It is speculated that the Kerr black hole is likely to connect two worlds!

Anyway, the idea of "shuttling through wormholes" is far from being realized, and there is only one possibility. And no one really dares to jump into some "Kerr black hole" for verification......

With the current technology, honestly using the curvature engine is already the best choice, in fact, most interstellar civilizations have also chosen this way, even L4 civilizations.

The most important thing in curvature navigation is to construct a "curvature bubble".

"It shouldn't be because of our technology, it's not that the level of plagiarism is not enough...... The curvature bubble structure of the Green Light Man itself is only 3 times faster than the speed of light. A space scientist explained.

"We're looking for ways to improve this technology to achieve higher speeds."

During this ultra-long voyage, people had to slow down often to observe the surrounding targets and adjust their direction at any time.

Aerospace engineering, the difference between a thousand miles and a thousand miles, must be absolutely precise, and human technology cannot reach the target at one time......

At this moment, more than two years have passed, and the "Deep Sky" has traveled a distance of 5.8 light years.

In order to ensure safety, it is necessary to stop and do a routine inspection.

This is the emptiest space in the universe, one light-year away from the nearest star, and there is not even a trace of meteorites in this place, only the "Deep Space" exists alone.

At this distance, all the stars have become ordinary stars.

The most terrifying place in the universe is not a meteorite pile, nor a planet with a harsh environment, but such an unremarkable interstellar space.

The matter here is unimaginably thin, almost an atom per cubic centimeter. Such a density is equivalent to spreading a drop of water evenly across a space of five million cubic kilometers.

The interstellar space is too empty, and if you are really trapped here, you will not be able to get material replenishment at all, and you can only wait for death slowly.

Without matter, there is no energy, and without energy there is no movement.

Yu Yifeng still had an inexplicable palpitation in the face of the vast universe...... Although the Noah was full of supplies......

He inexplicably remembered the days when he was short of resources and wandering after being blown up by the solar system......

As the supreme commander, his way of thinking is very different from that of ordinary people, and such and such worries have become a habit of thinking for him......

Born in sorrow and dying in peace, even if he becomes an interstellar civilization, his heart is not easy.

Of course, for everyone else, all life is no different. Everyone still lives in Noah, or is it reunited, and under normal circumstances, more than a billion tons of helium-3 can last for millions of years, and there is nothing to worry about.

It's just that astronomers are very busy.

During this time of maintenance, they were enthusiastically observing a nebula 6 light-years away, which was the one that humans had just escaped.

This nebula is like a glowing cloud, hidden behind the "187J3X1 binary", and a large amount of material thrown by the binary star forms part of the nebula.

The density of matter in the nebula is very low, and if you measure it by the standards of the earth, there are almost vacuums in some places, about 10-100 atoms per cubic centimeter, which is better than the real cosmic space.

Under certain conditions, nebulae and stars can transform into each other, and if the mass of the nebula is large enough, it may gradually shrink under the action of gravity. When the center of the gas mass becomes denser and hotter, it triggers a nuclear fusion reaction and the primordial star is born.

"Unfortunately, the mass of this nebula is not enough, and it is difficult to form stars. I think most of the material in this nebula has already formed a binary, and there is not enough left. ”

"It's almost impossible...... It's been a long, long time since the Milky Way became a zombie galaxy, and it is impossible to generate stars! ”

"The entropy of the galaxy has increased to the limit, and it is about to die......"

The two astronomers are debating excitedly, talking about stars, talking about the Milky Way, and discussing the "entropy increase theory".

For some reason, the Milky Way has not given birth to a new star for 1 billion years.

When the news was first announced, many people were shocked that the Milky Way, which seemed to have no difference, had gradually entered the end of time.

Of course, the Milky Way is still functioning normally, it seems that it can still run for tens or tens of billions of years, and human beings will not worry about when it will really die and die.

But the "death" of the galaxy is another proof of the "entropy increase theory", and nothing is eternal.

"Is there a peerless power that comes out and saves the galaxy?"

"We're still far from humans...... I don't know if the legendary S-class civilization is viable. The two astronomers teased each other.

Of course, when it comes to the death of the galaxy, they also feel inexplicably uncomfortable.

Why can't the Milky Way give birth to new stars? Humanity has not even figured this out, and there are still too many unsolved mysteries in the universe.

At this moment, an astronomer suddenly shouted: "The observations are out, there is water!" Digger 114 has a lot of moisture in the atmosphere! ”

"Probably liquid water!"

The news immediately attracted everyone's attention...... r
