Luo Feng's fleet continued to monitor the Black Water Hollow.

The space is still shrinking, as if an invisible giant hand is pinching out the "water" in the space.

Countless substances were born from the void.

Photons, neutrinos, dark tons, protons, neutrons, and atoms are precipitated from the void one by one.

I don't know how long it has been.

Inside Luo Feng's fleet.

"Report, the precipitation of the substance has stopped."

Luo Feng looked at the star map in front of him, the volume of this black water void expanded by about 3.7%, and when the vacuum decayed to the extreme, the volume of the black water void at that time expanded by 18.3%.

Obviously, the space has shrunk and restored some of the space that has expanded.

……

Huang Mingzhe's virtual projection is also watching the natural vacuum decay of the black water cavity.

"It seems that I understand some of the mechanisms by which the void appears in the universe." Duan Zangfeng muttered to himself.

Huang Mingzhe said with a smile: "Cosmic collision, to be precise, parallel cosmic collision. ”

"The chairman's eyes are like torches." Duan Zangfeng nodded.

Both of them can roughly deduce the mechanism by which the cosmic void is created.

That is the collision from parallel universes, the space that appears in the Black Water Void expands faster than the speed of light, that is, this universe and another parallel universe collide with each other.

In the process of colliding with each other, the space of the black water hole is caused, and in order to remove the interaction force of the collision, the space of the black water hole is caused to expand faster than the speed of light.

After the collision, the interaction force between the two universes disappears, causing space to shrink.

However, after the collision of the two universes, it is impossible for the space to return to its previous volume, and a part of the space will be semi-permanently added.

Huang Mingzhe asked Luo Feng to continue to observe this black water cavity, and deeply investigate the mechanism of natural vacuum decay, as well as related data.

Luo Feng naturally did not refuse this task, and led the fleet into the black water hollow to investigate this place in depth.

The first squadron rushed out of the wormhole, and the space that had just stabilized was filled with countless free particles.

Through the lookout window, Luo Feng saw an extremely strange picture.

The entire void is like a sea of photons, because photons are the first and easiest particles to precipitate from zero.

So here it becomes a sea of photons.

But in the ocean of photons, there are still black spots and all kinds of points of light, which is poorer than any region of the universe, but at this moment, it is more colorful and brilliant than any other area of the universe.

The dark matter precipitated in space is rapidly flattened, while the light matter is free of the surroundings.

Photons sputter in all directions, and neutrinos also pierce the void.

And the only thing that gave Luo Feng a headache was those protons and electrons.

Because protons and electrons have antiparticles, negative protons and positrons are also born in the process of spatial precipitation.

The positive and negative protons and positive and negative electrons of the entire void are annihilating each other at this moment.

You can see that outside the lookout window, the void is constantly flickering, which is the annihilation of positive and negative matter, releasing photons, neutrinos, and heat energy.

The ship's strong magnetic field shield, dark water layer, and degenerate armor block the effects of these positive and antimatter annihilation.

"It's no wonder that we found that some of the star systems in the Great Wall of the Universe around the Void Zone are unusually young, and there are generally no intermediate civilization bases." Zhou Yuan suddenly realized.

"Yes! If the universe collides at this level, once every few million years, the surrounding galaxies are estimated to not even appear as living planets. ”

"I studied the black water void through the light-chasing method, and the last time there was a cosmic collision of this level here was back 760 million years ago."

The light-chasing method, which jumps light years away through the wormhole, can observe a part of the past photons, and the farther the instantaneous jump distance, the longer the observed scene, and the accuracy of the information also decreases with the increase of distance.

"In this way, we can encounter a cosmic collision this time, or we will be lucky."

"Haha, it's better to have less of this kind of thing."

"That is, if we jump over and happen to encounter vacuum decay, we may receive a lunch box in an instant."

The crew was talking and laughing.

And the annihilation of positive and antimatter outside cannot be stopped without a period of wear.

If it is a space battleship of a primary civilization, it is estimated that it will be directly wiped out in this cosmic spectacle.

The results of supercomputing simulations show that it will take at least millions of years for such positive and antimatter annihilation to be completely eliminated.

The main reason is that the space of the cosmic void is vast, and the density of matter is very low, except for the peak period of annihilation at the beginning, after which the surrounding positive and anti-antimatter is exhausted, the remaining positive and anti-matter will slowly stabilize.

Like becoming atomic, or anti-atomic.

Sailing in the flickering void, there are also many wormhole interference areas, which continue to exist inside the black water cavern.

According to the current new theory, these natural wormhole interference areas are, to a certain extent, traces of other universes colliding with this universe.

As for these natural wormhole interference areas, why are they not as violent as the previous one?

The estimate is the size of the universe and the velocity of the two sides of the collision, in which the effect is made.

The larger the scale of the universe, the larger the wormhole disturbance area will be; Conversely, the smaller the size of the universe, the smaller the wormhole disturbance zone caused by the collision.

The collision velocity of the two universes will cause the intensity of the wormhole interference to fluctuate. The faster the speed, the greater the intensity of interference; The slower the speed, the less the intensity of the interference.

According to the derivation, "cosmic collision zone formula" and "cosmic collision velocity formula".

New human scientists can roughly calculate the radius, velocity, and mass of each parallel universe that collides with this universe.

This great discovery has made the new human beings attach great importance to it, and countless scientific research and research spacecraft have been dispatched to reside in various hollow regions of the universe.

Although the principle of natural vacuum decay and artificial vacuum decay is different, the result is exactly the same.

The vacuum decay observed by Luo Feng's fleet gave the new humans a preliminary understanding of the situation of vacuum decay.

It is estimated that those advanced civilizations also know about this natural vacuum decay, and the civilizations that study vacuum decay bombs must also be staring at these cosmic voids.

It's like looking at the sun's nuclear fusion reactions and studying the hydrogen bomb.

At least compared to making your own vacuum decay bomb to detonate, this method is safe and covert, and will not attract the attention of advanced civilizations.

If you detonate the vacuum decay bomb yourself, it is estimated that those advanced civilizations can immediately detect that they are artificially made.

Immediately, the reapers will be strongly watched, and when the time comes, trouble will definitely be overwhelming.

Luo Feng's fleet wandered in the Black Water Hollow, and during this time, he encountered many scientific research ships of other civilizations.

It's just that as soon as they saw that it was the fleet of the new human race, these scientific research spaceships of civilization did not dare to provoke Luo Feng's fleet.

After all, the impact of the war more than 30 years ago, the impact of the new humanity has not completely subsided.

These mid-level civilization research spaceships are only here to collect data, not to play with their lives, so there is no need to offend the new human race at all.

All parties are in peace, each doing their own thing, wandering silently in the hollow of the black water.

The deceased is like this, and the fierce tide of annihilation of positive and antimatter has passed for 3 years.

During this period, the 10 detachments of Luo Feng's fleet covered almost the entire Black Water Hollow.

Until one day, the Third Squadron sent back a strange message......
