Big Bang is the theory that the universe is smaller and hotter than it is now, it expands and cools over time. By understanding some important evidence, one can understand the foundation of the theory. The strongest evidence of the Big Bang is the movement of distant galaxies, the expansion of time and space, and hydrogen and photons in space. Measureing distant galaxies, distant galaxies are moving away from us. Distant galaxies are moving far away at a faster rate.
The big bang is the reason we are here today, I think that the existence of the universe is harder to believe than God. It is almost impossible due to the large explosion that caused the universe to eventually exist. If the Big Bang explosion diminishes by a fraction of a million gravity, it will surpass it, and it will collapse to itself before something can happen. If it is too large, planets and stars will not be created.
The Big Bang has strong evidence. But one big problem I encountered was that the children in the world have been taught by the Big Bang to create the universe and still being taught. There is strong evidence in the Big Bang, but there is no evidence that the Big Bang now created the universe and everything that exists. This theory is based on pure assumptions and is based on very weak / lazy inference in my opinion. In fact, the big bang may happen without creating the universe. The universe already exists
Before we know the universe where it exists, there is neither space nor time. The Big Bang and related theory attempts to describe or describe the moment of change of the universe from time to time to spaceless. Many physicists named this incident as an explosion or flash, hence Big Bang. Big Bang is the process of expansion in our universe and still still active today. The universe blinks from the accumulation of very dense and hot materials (according to Big Bang theory). In addition to containing hydrogen and a small amount of helium, it is a dense, hot, spherical gas and begins to expand outward rapidly. There are no stars or planets. The first star could have been formed in space about 200 million years ago. Our sun was formed 4.5 billion years ago, but through the telescope you can see that the star is composed of compressed hydrogen balloons in the universe.
