Big bang cosmology is a cosmological model that describes the origin and evolution of the universe. This model is supported by the most extensive and accurate scientific research and observation. Cosmologists usually call the Big Bang view that the universe evolved from an initial state with extremely high density and extremely high temperature a limited time ago. According to the best observation results obtained by Planck satellite in 20 15 years, BIGBANG was 137.99 0.2 1 100 million years ago, and reached its present state through the continuous expansion of space. The framework of the Big Bang model is based on Einstein's general relativity, and the solution of the field equation is also simplified to some extent (for example, the cosmological principle assumes that the space is homogeneous (physically) isotropic). 1922, Soviet physicist Alexander Friedman described the fluid with general relativity, thus giving the field equation of this model.

The+-sign in the figure represents the smallest inseparable unit of positive and negative chord information-string position.

(john wheeler, a famous physicist, once famously said: Everything comes from bit by bit.

After the prosperity of quantum information research, this concept has been sublimated to everything from quantum bits.

Note: One point is one point.
