I'm invincible at the start

Chen Tian's body is still drifting in the universe, but his consciousness seems to have returned to the place that made him think about Chaomu
His mind began to think of everything from the past, and the fragments of that memory began to appear in great numbers.

Eventually the scattered fragments of memory disappeared, and a picture began to emerge.

It was a more familiar picture, just at a speech he attended, it was that he was obsessed with the science fiction universe, and he bought all related books to read in detail.

And the person in that picture was a very famous foreigner science fiction universe lecture he attended at that time.

Those two people were talking about a story, while Chen Tian sat below and listened obsessively. He vaguely seemed to hear the man talking about the theory of the constant state of the universe.
At that moment, he remembered!

Chen Tian's soul consciousness was awakened, and he remembered those two people and the theory they were talking about. They were called Bondi Gold and Fred Hoyle.
Steady-state cosmology was proposed in 1948 by the young British astrophysicists Bundy, Gold and Fred Hoyle.

Their point of view is: in the theory of relativity, space-time is unified, and since the principle of cosmology holds that all spatial positions are equivalent, all moments should also be equivalent.

That is to say, the large-scale distribution of celestial bodies (matter) is not only uniform and isotropic in space, but also should be constant in time.

That is to say, in any era, the images of the universe seen by observers at any position are the same on a large scale, and this principle is called "the principle of complete cosmology".

Steady-state cosmology holds that the universe is infinite in both time and space.

It asserts that the universe never had a beginning, or rather, that the universe is in a continuous process of creation.

As the universe expands, the overall density decreases, but more matter is created to increase the density.

So as the universe continued to expand, new matter was continually created in the stars to fill the gaps.

The biggest feature of steady-state cosmology is that it requires that matter and energy are not conserved, and that the law of indestructibility of matter is not established.

For this reason, Hoyle proposed to modify Einstein's field equations, and he believed that the newly generated matter was generated by the vacuum phase transition caused by the transition of the newly generated vacuum from a high energy level to a low energy level.

Steady-state cosmology has caused a sensation after it was introduced, but this kind of major change in principle cannot be easily adopted, unless the new theory has made great achievements and is in good agreement with the observational facts, but in fact the steady-state cosmology Cosmology does not fit well with observations.

And the brane cosmology, why the brane universe exploded from a point with infinite density, or the singularity.

But no one knows what triggered the eruption: The known laws of physics can't tell us what happened at that moment.

"All physicists know that dragons probably came out of the singularity," said Nyaesh Afshordi, an astrophysicist at the Perimeter Institute for Theoretical Physics in Little Waterloo, Canada.

At the same time, it is difficult for scientists to explain why the universe left by such a violent Big Bang has an almost completely uniform temperature, because there does not seem to be enough time since the universe was born to reach temperature equilibrium.

For most cosmologists, the most plausible explanation for the consistency is that shortly after the universe formed, some unknown form of energy caused the young universe to expand faster than light.

This results in a roughly uniform temperature universe as we see it.

But Nyaesh Afshordi emphasized: "The Big Bang was so chaotic that it was difficult to know whether there was such an expansion."

In one paper, Nyaesh Afshordi and colleagues turned their attention to a study led by physicist Gera G. A hypothesis proposed by a research team including Cindy in 2000.

In this model, our three-dimensional universe is a membrane floating above a "bulk universe" with four spatial dimensions.

Nyaesh Afshordi's team realized that if the bulk universe contained its own [-]D stars, then some of those stars would collapse and eventually form [-]D black holes—unlike the massive masses in our Universe. Stellar works in a similar way.

These four-dimensional stars explode like supernovae and violently eject their outer layers while their inner layers collapse into a black hole.

In our universe, a black hole is connected by a sphere called the event horizon.

Whereas ordinary three-dimensional space requires a two-dimensional object to create a boundary inside a black hole, in the bulk universe, the event horizon of a four-dimensional black hole should be a three-dimensional object—a shape known as a hypersphere.

When Nyaesh Afshordi's team simulated the death of a [-]D star, they found that the ejected material was able to form a [-]D membrane around the [-]D event horizon that slowly expanded.

The researchers hypothesized that the three-dimensional universe we live in could be such a brane, and the growth of the brane we detected is thought to be the expansion of the universe.

"Astronomers observed this expansion and reasoned back that the universe must have started with a big bang - but it was a mirage," said Nyaesh Afshordi.

This model also naturally explains the consistency of our universe.

Since the [-]D universe may have existed for an infinite amount of time in the past, it has had ample opportunity to bring the [-]D universe into a balance in different regions, and our [-]D universe has likely inherited this.

Brane cosmology is a branch of superstring theory and M-theory in physics, specializing in the study of cosmic branes. The theory believes that the universe is actually embedded in some higher-dimensional branes.This discipline also studies how those higher dimensional branes affect our universe.
When the memory came here, fragments appeared again. Chen Tian was puzzled. At that moment, he seemed to have really returned to the earth.
Does the illusion as real come from the depths of the memory, or is it just the illusion of the soul caused by some reason?
He didn't know, not even where he was.
His memories kept reappearing, and those scattered fragments seemed to contain some important information.

Chen Tian wondered why his memory would stay where he was when he was listening to a foreigner's lecture on earth, but not at other times.

What's the connection?
Could it be that something in the memory is constantly reminding me?
