If the universe was born 13 billion years ago, what was the world like before that?

Life on Earth was born 4.6 billion years ago, and humans were born 30 million years ago. The universe was born even earlier, according to scientists, about 13 billion years ago. The age of the universe today is calculated based on the theory of the great universe, which holds that our universe was born from a great world.

The theory of cosmic grandism holds that the universe is a point with infinite mass, infinitely small volume, and infinite density before it was born, referred to as singularity.

This singularity occurred 13.7 billion years ago, and then the universe was born, at the beginning of the big **, matter can only exist in the basic forms of neutrons, protons, electrons, photons and neutrinos, the temperature of the universe continues to drop, with the decrease in temperature, the gradual formation of atomic nuclei, atoms, molecules, and composite to form the usual gas, gas and gradually condense to form nebula, nebula further forms a variety of stars and galaxies, and finally forms the universe we see.

In 1929, the American astronomer Hubble discovered an astonishing fact when observing the galaxies near the Milky Way: that is, he found that almost all galaxies are diverging from each other, and the faster they are leaving each other, this discovery gave birth to the theory of cosmic expansion, which is also the basis of the theory of the universe.

Maybe our universe is just a part of a living being that is growing.

According to Hubble's observations, later generations further explored the theory of cosmic expansion, and now the expansion rate of cosmic expansion has been measured, and based on this not too accurate number, scientists have come up with the theory that the cosmic expansion rate exceeds the speed of light. This theory suggests that galaxies will leave the Earth faster than the speed of light at a distance of about 13.7 billion light-years away from the Earth, and it is precisely because of this that scientists have come to the conclusion that the age of the universe is 13.7 billion years old, although this number is not very accurate, some say 14.4 billion light-years, but this does not matter, just know how it came about.

The farthest place that can theoretically be seen on Earth is a galaxy 13.7 billion light-years away from Earth, and even if there is anything beyond this distance, we can't see it. So what would a universe look like 13.7 billion years ago, just before the universe was born?

Scientists are reluctant to discuss this issue and think that there is no meaning, but some philosophers are happy to discuss it, because they believe in the theory that the Creator created all things, and in their opinion, before the birth of the universe, there must have been a Creator who prompted the creation of the universe, and then there was the universe that we can see now.

With the concept of Taoism, the Tao is Taoist, and it is very Tao. Stunner, the beginning of heaven and earth. Nothing, the mother of all things.

Before the birth of the universe, there was no time, no space, everything did not exist and there was no meaning, and the universe would not know what the world was like before it was born. Perhaps this is our limitation in the universe.

According to the current theory of the universe, before the universe was created in space, the universe was a singularity, and this point was not the point we know, but a state, a critical singularity state.

I guess there was nothing to be discovered in the world before the universe was born, but I think that before the universe appeared, the world should have been chaotic, like a huge gray sphere.

Before the birth of the universe, was there any kind of slow scum? There is no definitive answer to this question. At the moment, scientists can only come up with a few hypotheses.

When the universe shrinks to the extreme, it becomes one"Singularity", after that"Large**"It will happen again, and the universe will expand again until the next contraction. And so on and on, and on.

Brian Universe Hypothesis. "membranes"The theoretical basis of the model of the universe comes from:"m "theory, the model assumes that one is called"Universe"high-dimensional space, and there are many in this high-dimensional space"membranes"Universe, Liang shouted because of all"membranes"The universe is gravitational, so they can collide with each other, the so-called"Large**", which is a collision between membranous universes.

The bubble universe hypothesis. All of them"Bubble Universe"are all there"Metaverse", while"Metaverse"is an eternal being. In infinity"Metaverse"Medium,"Bubble Universe"It is constantly generated, then expanded, and when it expands to its limit, it bursts, and then it returns"Metaverse"。

<> the chaos hypothesis. This hypothesis can be simply described as follows: Before the birth of the universe, there was no matter, time, and space, so there was no causal relationship, only chaotic energy.

The Black Hole Universe Hypothesis. Theoretically, anything with mass can become a black hole, provided that the natural radius of the object is less than the Schwarzschild radius, for example, the Schwarzschild radius of the Earth is about centimeters, that is, if the radius of the Earth is compressed to less than a centimeter (with no change in mass), then the Earth will become a black hole.

The high-dimensional cosmic projection hypothesis. Our universe may be a high-dimensional space projected through three-dimensional space, so-called"Singularity", in fact, when the high-dimensional space has just come into contact with the three-dimensional space"Dot", since the current projection process is gradually"Get bigger", at this stage so we can observe"The universe expands"phenomenon.
