Chapter 337 A Long Journey

The universe is huge and boundless, hiding countless secrets.

During this voyage, Yu Yifeng stood in the captain's room, thinking absentmindedly...

Strangely, the curvature engine is only L2-level technology, which seems to be the greatest gift of the universe...

Curvature navigation that exceeds the speed of light is not restricted by relativity, and it saves more energy than conventional navigation. It is also curvature navigation that makes it easier to roam between stars...

And strange matter is a special substance needed for the curvature engine. As a kind of dark matter, it is hidden in space and can be said to be almost everywhere.

Strange matter can not only distort space, but also cause space-time vortex when its quantity is large enough.

Just like the whirlpool in the sea, which can make the local water surface and the bottom of the water closer, this space-time vortex can make two relatively far local spaces close to each other in an instant...

That is... the "wormhole" in science fiction!

According to this theory, some people assume 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.

In the dark matter theory, using wormholes for long-distance shuttles has become possible from fantasy.

But unfortunately, the strange matter required to open a wormhole is too much, far beyond the current human tolerance.

At the energy level of humans, only wormholes slightly larger than the Planck length can be opened, and this length cannot accommodate a quark.

Moreover, in the experiment, people found that the duration of this ultra-small wormhole is also very, very short, and it quickly explodes into a cluster of particles in a short time of 10 to the negative 27 seconds.

This phenomenon... is very similar to a micro black hole, which directly triggered scientists' deep thinking!

People are thinking: What is the relationship between "black holes" and "wormholes"?

Yu Yifeng is very interested in these cutting-edge sciences. He has been studying during his free time. For any interstellar civilization, of course, the faster the better... Wormhole technology is of course much more advanced than the curvature engine.

Some scientists believe that wormholes may connect parallel universes and baby universes, providing the possibility of time travel. Some people think that time travel is impossible, but it is possible to instantly cross a long distance through a wormhole...

Some people think that wormholes may be space-time tunnels connecting black holes and white holes, so they are also called "gray paths"...

From this... another black hole science has been derived: a certain black hole with angular momentum is actually a wormhole!

This kind of black hole is called a "Kerr black hole". People speculate that the Kerr black hole is likely to connect the two worlds!

Anyway, no matter what, the idea of ​​"traveling through wormholes" is far from being realized, and it can only be a possibility. No one really dares to jump into a "Kerr black hole" to verify it...

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

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

"It shouldn't be due to our technology, nor is it due to our lack of plagiarism... The curvature bubble structure of the Green Light Man is only 3 times faster than the speed of light." A space scientist explained.

"We are trying to improve this technology to achieve a higher speed."

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

In aerospace engineering, a slight error can lead to a great error. It must be absolutely precise. Human technology cannot reach the target in one go...

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

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

This is the most empty space in the universe, one light year away from the nearest star. There is not even a trace of meteorite in this place, and 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 pile of meteorites, nor a planet with a harsh environment, but such an ordinary interstellar space.

The matter here is so thin that it is unimaginable, with almost one atom per cubic centimeter. Such a density is equivalent to spreading a drop of water evenly in a space of 5 million cubic kilometers.

Interstellar space is too empty. If you are really trapped here, you can't get any material replenishment at all, and you can only wait for death slowly.

Without matter, there is no energy, and without energy, you can't move.

Facing the vast universe, Yu Yifeng still has an inexplicable palpitation... Although the Noah is full of supplies...

He inexplicably remembered the days of wandering in anxiety after being blown out of the solar system with insufficient resources...

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

Born in worry and died in comfort, even if he has become an interstellar civilization, his heart is not at ease.

Of course, for other people, all life is no different. Everyone still lives in Noah and is still reunited. Under normal circumstances, more than one billion tons of helium-3 can be used for millions of years, and there is nothing to worry about.

It's just that astronomers are very busy.

During this period of maintenance, they were observing with great interest a nebula 6 light years away, which was the one that humans had just escaped from.

This nebula was like a bright cloud, hidden behind the "187J3X1 binary star". The large amount of matter thrown out by the binary star formed part of the nebula.

The density of matter in the nebula is very low. If measured by the standards on Earth, some places are almost vacuum, with about 10-100 atoms per cubic centimeter, which is better than the real universe.

Under certain conditions, nebulae and stars can transform into each other. If the mass of the nebula is large enough, it may gradually shrink under the action of gravity. When the density of the central part of the gas group becomes higher and higher, the temperature becomes higher and higher, which triggers a nuclear fusion reaction, and the original star is born.

"Unfortunately, the mass of this nebula is not enough, and it is probably difficult to form stars. I think most of the matter in this nebula has formed binary stars, and the remaining is not enough."

"It is almost impossible... The Milky Way has been a zombie galaxy for a long time, and it is impossible to generate stars!"

"The entropy of the Milky Way has increased to the limit and is about to die..."

The two astronomers are arguing excitedly. They discuss stars, the Milky Way, and the "entropy increase theory".

For some reason, the Milky Way has not produced new stars for 1 billion years.

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

Of course, the Milky Way is still operating normally. It seems that it can still operate for tens or tens of billions of years, and humans will not worry about when it will really die and disappear.

But the "death" of the Milky Way is another proof of the "entropy increase theory". Nothing is eternal.

"Is there any peerless power coming out to save the Milky Way?"

"We humans are far from it... I don't know if the legendary S-level civilization is feasible." The two astronomers teased each other.

Of course, when talking about the death of the Milky Way, they also felt inexplicably uncomfortable.

Why can't the Milky Way produce new stars? Humans haven't even figured this out yet, and there are still too many unsolved mysteries in the universe.

At this time, an astronomer suddenly shouted: "The observation results are out, there is water! There is a lot of water in the atmosphere of Dig 114!"

"There is probably liquid water!"

This news immediately attracted everyone's attention...
