A lot of theoretical physicists' research is based on utopia, so there are all kinds of strange things, and even some ridiculous ideas are proposed.

So after being in contact with Lorenz for a long time, Lin Xiao also has a deeper understanding of these people.

For what Lorenz said, Lin Xiao would at most find it interesting, but he would not really think that these theories could be true and credible.

At least in his opinion, the end of the universe is a very distant thing, at least for ordinary people, it is not visible, and for the entire human civilization, it is also invisible, and I don't know how many billion years later.

According to the Great Tear theory, dark energy will distort the structure of the universe, causing galaxies to tear apart first, followed by smaller black holes, planets, and stars.

The drag of the cosmic expansion continues to increase, and once it reaches a point that exceeds the gravitational pull that holds galaxies together, a big tear occurs.

The universe will eventually expand at the speed of light, and at this moment, the forces that bring matter together will be torn apart.

Eventually, the universe will come to naught, with only a single particle and no connection to any other matter in the universe.

A few years ago, researchers said the universe was expanding at a rate relative to a roller coaster.

Prior to this conclusion, they first mapped galaxies that formed 11 billion years ago, and found that the growth of the universe in its youth was slowed by gravity, but in the past 5 billion years, the universe has begun to expand rapidly due to the influence of a mysterious dark energy.

Another possible way for the universe to end is called the Great Contraction, which occurs when the matter in the universe decreases over time, causing gravity to become the dominant force.

Gravitational pull causes the universe to contract, and as a result, stars, galaxies, and planets collide with each other, and the universe collapses.

Theoretical physicists say that some regions of the universe have begun to collapse, and this collapse will eventually engulf other regions of the universe.

Undoubtedly, this is a frightening theory, and they even proved it with mathematical equations, a violent process called a "phase change", similar to water turning into steam or a magnet losing its magnetic force when heated.

According to the Higgs theory, this phase transition occurred in tens of billions of a second after the Big Bang, resulting in a change in the structure of space-time.

In this process, the vacuum region is filled with an invisible substance, called the Higgs field, with which some elementary particles interact with each other, and this intrinsic energy is called the mass of the particle.

With the help of mathematical equations, the researchers found that the Higgs field can exist in two states, just as matter exists in a solid or liquid state.

In the second state, the density of the Higgs field is billions of times greater than scientists have observed.

If such a super-dense Higgs field exists, in this state, a defined region of the universe will suddenly appear at any moment with a "bubble", like water boiling, and this bubble will then expand at the speed of light, entering all regions of space, changing the Higgs field from this state to its current state.

The last hypothesis of the Great Freeze, which is most consistent with current knowledge of physics, is also the most likely to occur.

According to this hypothesis, humans either see the Great Freeze or see a heat death.

Matter slowly decays into radiation as the universe expands, and after trillions of years of change, even the atoms that make up the rest of the matter begin to decay and disintegrate, stars will eventually dissolve, black holes will evaporate, and even light particles will eventually disappear.

"The question of whether the universe has a lifespan is not something we can understand." Lin Xiao looked at Lorenz and said to him, "Or, judging from our current wisdom, it is not realistic to figure out this situation. ”

Although Lin Xiao's words sound a bit demeaning to the ingenuity of the entire human race, from a practical point of view, it is not a fallacy, after all, people have not even gone out of the solar system now, and their understanding of the more distant interstellar space only relies on astronomical observations and conjectures.

Such an understanding is likely to be full of errors or even completely opposite cognitions, and the conclusions drawn under such a premise are naturally absurd and ridiculous.

How to put it, it's as ridiculous as the toad sitting in the well and watching the sky.

"I knew that, too, so I went and asked Miss Niya." Lawrenz said with a sad face, "Miss Nia said that this possibility still exists, and it is indeed as we said, in some areas of the universe, this situation is happening, they call those places the Death Star Field, even the most powerful spaceship, dare not get closer, and after a certain period of time, the scope of the Death Star Field will expand a lot, and eventually it will definitely swallow the entire universe." ”

"So, that means it's happened and continues to happen?" When Lin Xiao heard this, he asked, "In that case, don't Niya and the Klox people have any ideas?" After all, they are a very high-level alien civilization. ”

If the Clovians are helpless against this change, then the earthlings have little way to solve it, which is almost obvious.

After all, the possibility of earthlings defeating aliens in Hollywood movies is almost impossible to exist, in terms of individual ability, there is such a possibility, but from the perspective of civilization, this thing is absolutely impossible.

For things outside the solar system, the Clovians of the alien civilization obviously know much more than the earthlings.

"I did ......ask about this," replied Lorentz, "but Miss Nia said that it was something that could not be solved at all, so the Clovians would not spend time and energy thinking about those meaningless things, and even if they wanted to, they would not find a solution, and it would be better to enjoy life as much as possible." ”

"yes, Niya is not wrong at all." Lin Xiao shrugged his shoulders, "This kind of thing is not something we can consider at all, why force yourself into a dead end?" There's no need for that. ”

"However, we did find a collapsing area in the interstellar depths not far from the solar system by observation......" Lorentz said of the incident with a somewhat mournful expression, "and, according to the speed of change of that thing, it may not take a few decades to swallow up the solar system, and then we will not be able to escape at all." ”

"What?" After Lin Xiao heard this, he couldn't help but be taken aback, and finally couldn't sit still.

If it's just a theoretical guess, it doesn't matter, after all, it's too far away, and God knows how many years will be gone by the time the collapsed area is passed over.

But now, according to Lorentz, that thing has appeared in the interstellar depths not far from the solar system, and is devouring everything nearby, this thing is a bit shocking to Lin Xiao.

After all, this kind of thing is like a tumor inside the human body, which may develop slowly at the beginning, maintaining a small scale for more than ten years or even decades, but suddenly it begins to explode sharply, and the entire human body can be destroyed within a few days.

If, as Lorenz says, that thing is likely to swallow up the solar system in a few decades, what is the way for humanity to survive?

At the very least, there are no resources on Earth that can provide humans with large-scale interstellar migration, and with the current situation of humanity, it will take a very large investment to get out of the solar system, and it will take a long time.

In other words, before humanity can prepare all the conditions for the Great Escape, the collapsed area should have swallowed the entire solar system and even the wider starry sky.

Such a thing is really unavoidable, no wonder Lorentz is so depressed.

"This is an unsolvable proposition!" After Lin Xiao figured this out, he couldn't help but rub his temples with a little headache.

If the situation is really as Lawrenz said, this matter is indeed unsolvable, even if Lin Xiao can cooperate with aliens, what problem can he solve?

In response to the problem of the collapse of the universe, it is estimated that the entire interstellar civilization has no way to solve it, and the only way to avoid it is to avoid it from afar, but there are actually few interstellar races that have the ability to dodge.

What's more, now that the entire earth is trapped by the Twelve Heavens Chaos Array, even if it has the ability to travel interstellarly, it will not be able to escape the solar system at all.

"Is there any solid evidence to prove this?" Lin Xiao had a headache for a while, but finally calmed down a little, and then asked this question.

After all, the collapse of the universe is a very terrifying thing, and through extraterrestrial observation, some relatively strong evidence should be seen, otherwise, it is very likely that this matter is just a misunderstanding, but this misunderstanding is indeed a bit scary.

"Yes, we did observe some things with the help of state-of-the-art radio telescopes." Lorenz immediately pulled out a stack of information pictures from his briefcase.

These pictures are printed with the most advanced technology and look very clear.

It's just that no matter how clear the picture is, it is also magnified by the interstellar observation results after I don't know how many times, so it still looks a little hazy, like a black fog, the only difference is that some of it is a virtual existence that is darker than the black fog.

"Oh, is that all that?" Lin Xiao picked up those pictures and then looked at them carefully.

Lin Xiao found that these darkest spaces seemed to have nothing anymore, and this thing was faint, as if there was a little bit of a regular shape, which made people have some very bad associations after looking at it.

"It's these things, these are the latest information we have obtained, but compared to the information obtained in the previous month, this thing has been significantly expanded, and it is visible to the naked eye." Lorenz pointed to some of the outlines on the picture and explained to Lin Xiao.

"It seems that the situation is not optimistic...... Lin Xiao looked at the results observed before and after under the guidance of Lorentz, and couldn't help frowning.

Obviously, the range of the thing on the map is indeed expanding, and according to this speed, its infection speed should be very amazing, and it can even completely swallow the light, which is much more powerful than the legendary black hole.

After all, a black hole is nothing more than a powerful gravitational space formed by a collapsed star, and this cosmic collapse is more like something that completely changes the properties of space, and people can't think of any way to fight it.

"Hey, why does this thing look familiar?" Lin Xiao looked at it for a while, and suddenly had a very strange feeling, he always felt that the darkness seemed familiar.
