The universe is large, boundless, and hides countless secrets.

During this voyage, Yu Yifeng stood in the captain's room and thought...

Oddly enough, the curvature engine turned out to be only L2-level technology, which seems to be the greatest gift of the universe.

Voyage beyond the speed of light does not be subject to the conditioning of relativity, and is more energy-saving than conventional navigation.It is also the curvature that makes it easier to roam between stars and stars.

Strange matter is a special substance that needs to be used in the curvature engine.It acts as a kind of dark matter, hidden in space and almost ubiquitous.

Strange matter can not only distort space, but when its number is sufficient, it can also cause a vortex of space-time.

Just like the vortex in the sea, which can bring the local surface closer to the bottom of the water, this space-time vortex can make two local spaces that are far away from each other very close in an instant.

That is, the “wormhole” in the scientific fantasy!

According to this theory, some people hypothesize that if there is a strange substance called phantom matter, because it has both positive energy and negative mass, it can create a rejection effect to prevent the wormhole from closing.

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

The use of wormholes for long-distance shuttles, in dark matter theory, from fantasy to the possibility.

Unfortunately, opening the wormhole requires too much strange material, far beyond the current capacity of humans.

At the human energy level, you can only open a wormhole slightly larger than the Planck length, which is not a quark.

And in the experiment, it was found that the duration of this ultra-small wormhole was also very, very short, and it quickly exploded into a cluster of particles in a short period of time of minus 27 seconds.

This phenomenon ... is very similar to that of micro-black holes, which directly triggered the deep thought of scientists!

People are thinking: "black hole" and "wormhole" what does this really have to do?

Yi Feng is very interested in these cutting-edge science, and has been learning during this time.For any interstellar civilization, of course, the faster the flight, the better... wormhole technology is certainly much higher than the curvature engine.

Some scientists believe that wormholes may be able to connect parallel universes with infant universes, providing the possibility of time travel.Some people think that time travel is impossible, and it is possible to span a long distance in an instant 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 roads".

As a result, another black hole is derived: some kind of black hole with angular momentum is actually a wormhole!

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

In any case, the idea of “shuttleing with a wormhole” is still far from being realized, and there can only be one possibility.No one really dared to jump into a “Kel black hole” for verification...

With the current technology, the honest use of curvature engines is already the best choice, in fact, most interstellar civilizations are also selected, even the L4 civilization is the same.

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

“It should not be our technical reason, nor is the level of plagiarism enough... The curvature bubble structure of the Green Light Man is only three times faster than the speed of light.”A space scientist explained.

“We are looking for ways to improve this technology to achieve higher speeds.”

In this ultra-long-distance voyage, people often have to slow down to observe the surrounding targets and adjust their navigation direction at any time.

Space engineering, thousands of miles away, must be absolutely accurate, human technology can not go directly to the target at once...

At this moment, after more than two years of sailing, the "Deep Space" ran a distance of 5.8 light years.

In order to ensure safety, you need to stop and do a routine test.

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

At this distance, all the stars become ordinary stars.

The most terrible place in the universe is not a meteorite pile, nor a planet with a bad environment, but such an ordinary interstellar space.

The material here is so thin as unimaginable, almost a cubic centimeter an atom.Such a density is equivalent to spreading a drop of water evenly in five million cubic kilometers of space.

Interstellar space, too empty, if you are really trapped here, you can't get a material supplement at all, and you can only slowly wait for death.

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

Yu Yifeng faces the vast universe, still has an inexplicable paletty feeling... Although Noah is full of materials...

He remembered inexplicably that after the solar system was bombed out, there were insufficient resources and wandering days...

As the supreme commander, his way of thinking is very different from ordinary people, so such worries, has become a habit of his thinking.

Born to die of sorrow and happiness, even if it becomes an interstellar civilization, his heart is not easy.

Of course, for others, all life is no different.We still live in the Noah, or reunite, usually, more than a billion tons of helium-3 can be used for millions of years, there is nothing to worry about.

Astronomers are very busy.

During this period of maintenance, they are excitedly observing a nebula six light-years away, the group that humans have just run out of.

This nebula is like a shiny cloud, hidden behind the "187j3x1 double star", the binary throws a lot of material, and also form part of the nebula.

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

Under certain conditions, nebulae and stars can transform each other, and if the nebula mass is large enough, it may gradually shrink under the influence of gravity.When the density of the central part of the gas group is getting larger and higher and higher, it triggers the nuclear fusion reaction, and the original star is born.

"Unfortunately, the mass of this nebula is not enough, and it is difficult to estimate the formation of stars."I think most of the material in this nebula has formed double stars, and the rest is no longer enough.”

“It’s almost impossible... the Milky Way has been a zombie galaxy for a long time, and it’s impossible to generate stars!”

“The entropy of the galaxy has been increased to its limit, and it is about to die...”

The two astronomers are debating excitedly, discussing stars, discussing galaxies, discussing the "entropy increase theory."

Not knowing why the Milky Way has not had a new star in a billion years.

When the news was just announced, many people were shocked, and the seemingly indistinguishable galaxy had gradually entered the end of time.

Of course, the Milky Way is still working normally, it seems to be running for tens or billions of years, and humans 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 any power out there to save the galaxy?”

“We humans are far from it... I don’t know if the legendary S-class civilization is feasible.”The two astronomers laughed at each other.

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

Why can't the galaxy give birth to a new star?Humans have not even understood this, and there are still too many unsolved mysteries in the universe.

At this time, an astronomer suddenly shouted: "The observation came out, there is water!"Digg 114 has a lot of water in the atmosphere!”

“There’s probably liquid water!”

This news immediately attracted everyone's attention...
