Chapter 74 The Birth of the Universe
"How many did you say?"

Hearing the number Jin reported, Gu Wei couldn't help but scratch his eyebrows: "Ten to the power of -66 seconds?"

I'm a bean
A civilization that only existed for ten to the negative 66th power seconds, or during the period when the universe was first created?

The innate gods and demons in the prehistoric novels didn't die so quickly.
Looking at Gu Wei, who was full of questions, Jin suddenly thought of herself who was equally ignorant back then. She gently touched the Weaver's Necklace:
"It's confusing, isn't it? Why would a civilization that existed for such a short time be called the most powerful?"

Gu Wei nodded.

He really couldn't figure it out.

Assuming that this civilization does exist, it is certainly mysterious enough, but how can it be called the most powerful?

Also, what does the Twilight Trigger have to do with the other party?
"Let me ask you a question first," but this time Jin did not give a direct answer like before. Instead, he asked Gu Wei: "What does the Earth think about the birth of the universe?"

"The birth of the universe?" Gu Wei blinked. This was a business topic. "There are many discussions on this topic on Earth. Excluding those weird folk scientists, there are basically three views in the industry - the Big Bang theory, the eternal expansion theory, and the return theory."

"Among them, the inflation theory holds that the universe never had a beginning and will never end. It has been expanding and will produce different universes in different places - there are "cosmic membranes" or "cosmic bubbles" between these universes, and the physical laws and constants in each universe are also different."

"The cosmic regression theory holds that the universe undergoes expansion and contraction over a certain period of time. When the universe contracts to a certain extent, it will explode and expand again, entering a new cosmic cycle."

"But the most widely accepted theory before I traveled through time was the Big Bang hypothesis, which holds that the universe originated from a high-density, high-temperature, high-energy matter "singularity". As time went on, this matter exploded and expanded in an instant, eventually forming the universe."

As an astrophysicist, Gu Wei can easily come up with cosmic hypotheses.

Just as he said.

Putting aside some strange theories, there are actually not many cosmological hypotheses that are supported by mathematics and physics.

For example, the theory of eternal expansion of the universe is a combination of general relativity and quantum field theory, with dark energy as its core. Its current supporters include Andre Linde, the BICEP project team and many other top scholars.

The cosmic regression theory has fewer supporters. You even have to search its English name "Cyclic Universe Theory" to find a more reliable framework. Its supporters are mainly concentrated in several universities and institutions in Gaul and Australia.

The Big Bang hypothesis is still the most accepted one among the public and academic circles.

Before Gu Wei traveled through time.

From astronomical observations, people can trace the history of the universe back to the period of primordial nucleosynthesis, which was about 3 minutes after the birth of the universe.

In theory, current theoretical research can trace the history of the universe back to the period of inflation, which is about 10^-30 seconds after the birth of the universe - this is the earliest cosmological event, or the earliest period, that modern cosmological theory can trace back.

At the beginning of the inflationary period, the universe was very small.

At this time, there exists a special material field in the universe, called the inflation field. This field has very large vacuum energy, which can drive the universe to undergo violent exponential expansion.

Through current astronomical observations, it can be basically confirmed that during the inflation period, the size of the universe expanded by at least about 10^25 times.

After inflation ended, almost all the energy of matter in the universe was stored in the inflation field, and the temperature of the universe became very high. When 10^-10 seconds passed, the temperature dropped slightly, and the asymmetry of matter and antimatter and the breaking of electroweak symmetry appeared - just like a bubbling hot pot, when the temperature dropped, peppers and other things began to sink to the bottom, and butter froze on the top.

That is, matter begins to separate into layers.

Then at 0.0001 seconds.

When the temperature drops to the order of 100 MeV, quarks begin to hadronize and neutrinos decouple in the first second.

The third second, primordial nucleosynthesis - Currently, almost all astronomical institutions have calculated the abundance of light elements (such as deuterium and helium-4) formed in primordial nucleosynthesis, that is, their proportion in the universe, and verified the calculated values through astronomical observations.

The vast majority of measurement results are in good agreement with the calculated values of the Big Bang theory, which is also regarded as one of the core evidences of the Big Bang theory.

This is how physics works. Even the derivation of a hypothesis requires complex calculations and verifications, and the orders of magnitude involved are often tens to the power of ten.

So when you have a certain understanding of the relevant information, you will find out how ridiculous it is for those amateur scientists who wrote 500 words and claimed to have overturned the theory of relativity.
His eyes returned to reality.

"10^-30 seconds." Jin Jingjing listened to Gu Wei's introduction and couldn't help but raise her eyebrows: "To be honest, for an astrophysical community at the level of a planetary civilization, it is not easy to be accurate to this level."

"But this accuracy is still far from enough to pursue the truth of the universe."

As he spoke, the image in front of Jin changed again: "Based on the various clues gathered by the Xinghai Civilization, it is now basically certain that the birth of the universe is indeed related to an explosion."

"But this explosion was not the kind of singularity explosion you imagined. It was an unexpected change in the tower space."

Gu Wei was stunned: "An unexpected incident?"

"That's right," Jin drew a flat rectangle in front of Gu Wei. "It's difficult to understand the true structure of the tower with your current knowledge framework, so I will try to use examples that you can understand. Have you seen the floor?"

Gu Wei nodded.

Of course he is not unfamiliar with this thing, and it is impossible for him to be unfamiliar with it.

"The floor has two sides, the upper and lower sides. The ground beneath your feet is actually the ceiling of the lower level," Jin said, pointing to the rectangle.
"In the tower model, the upper and lower sides of the floor have completely opposite properties, but at the same time, it ensures that matter can circulate along the surface, maintaining a special balance as a whole."

"But one day, an accident happened - a group of termites bit through a fatal hole in one of the floors inside the tower."

"However, due to the special nature of the tower, this floor did not collapse completely. Instead, the two forces above and below merged to form a new space through the explosion."

"As for those termites?"

Jin sighed, looked at Gu Wei who was in a trance and said:
"After biting through the floor, it died from the crushing of the tower's rules."
