What is the big bang theory?
The Big Bang Theory is known as a scientific model that describes the origin of the universe and how it developed after that. It is considered the prevailing cosmic explanation that sets a possible vision for how the universe began and developed over time, until it reached its current known form, according to According to this theory, the vast universe began from a very hot, dense, and compressed state approximately 13.8 billion years ago, then it began to expand and expand very rapidly, and continued to expand and expand until the present time. The Big Bang theory believes that the vast, massive universe originally began from A very small, very dense point known as a singularity point. At this point, space, time, matter, and energy were all compressed into a very small, and also very hot, area.
The Big Bang theory holds that about 13.8 billion years ago, a small, dense, hot single blob underwent extremely rapid expansion, or expansion, which can be likened to an extremely big bang; It led to the creation of vast space and time as we know them now.
The Big Bang theory holds that not only the universe is expanding, but space itself is also expanding. This means that galaxies and other cosmic structures are moving away from each other as the space between them expands. The rate of this expansion in astronomy is described using the Hubble constant.
The Big Bang theory holds that over thousands of billions of years, matter in the universe began to clump together under the influence of gravity, eventually creating clumps of material, including galaxies, stars, and other cosmic structures.
