Where did BIGBANG happen?

Where did the big bang happen? In which constellation? Will we observe more young galaxies in which direction and more old galaxies in the opposite direction?

The most common misconception about the Big Bang is that it happened somewhere in space, just like an exploding Grenade, and the galaxy is the shrapnel produced by the explosion. In fact, the Big Bang brought not only matter, but also space itself. Then the expansion of space makes the matter in space thin. In other words, the big bang happened where you are now and anywhere else.

The short term that can be clearly stated in the elevator is: the big bang happened everywhere at the same time; Everywhere is from small to large. Think about this sentence carefully and you will understand.

Big Bang, also known as the Big Bang, is a cosmological model that describes the origin and evolution of the universe. This model is widely and accurately supported by scientific research and observation today. 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 years ago? 0.2 1 100 million years, and achieved today's state through continuous expansion.

The earliest and most direct observational evidence of the Big Bang theory includes Hubble expansion observed from the redshift of galaxies, the fine measurement of cosmic microwave background radiation and the abundance of light elements in the universe (see initial nuclear synthesis). Nowadays, large-scale structure and galaxy evolution have also become new supporting evidence. These four kinds of observational evidence are sometimes called. Four pillars of the Big Bang Theory?
