When the vacuum zero field evolves into Minkowski vacuum (the induced reason is unknown), the vacuum energy is materialized, resulting in solid energy, from which matter is generated according to E = MC 2. The energy of the Big Bang scattered matter everywhere, which is the expansion of the universe. In the process of material expansion, nebulae, galaxies, stars, planets and other celestial bodies are produced through self-organization and structure.
The appearance of human beings is the inevitable result of the evolution of life on earth, but now more and more people think that the appearance of human beings on earth is purely an accidental phenomenon of the evolution of life on earth. If life evolves again, human beings may not appear again.
BIGBANG is a cosmological model that describes the initial conditions for the birth of the universe and its subsequent evolution. This model is supported by the most extensive and accurate scientific research and observation. Cosmologists usually refer to the view of the Big Bang: the universe evolved from an initial state of extremely high density and extremely high temperature a finite time ago, and reached its present state through continuous expansion.
Extended data:
Cosmic theory holds that the universe may be a negative curved shape like a saddle. This theory originated from the big bang theory. The whole universe looks like a balloon and we live on the "surface" of the universe.
At the same time, scientists also believe that the universe is flat. According to NASA, the universe may be flat. 20 13 survey found that if the universe is flat, the error is only 0.4%.
Stephen Hawking said that the shape of our universe may be an incredible geometric figure, which is closer to surrealist art, just like the figure created by Dutch artist Moritz cornelius escher.
If the energy density of the universe is equal to or less than the critical density, the expansion will gradually slow down, but it will never stop. Star formation will eventually stop because the interstellar gas in each galaxy is gradually consumed; The evolution of stars eventually leaves only white dwarfs, neutron stars and black holes. Quite slowly, the collision of these dense stars will lead to mass accumulation and gradually produce larger black holes.
