Let's talk about the Big Bang Theory. The Big Bang Theory is the leading explanation of how the Universe started. It happened 13.7 billion years ago. In 1927 there was the theory of how we began by Belgian Catholic, Priest Georges Lemaître
One type of evidence that has been used to support the Big Bang Theory is star light spectrum. So if the light emitted by most stars and galaxies in the universe is shifted to the red end of the spectrum. Then they are moving close to us
The Big Bang Theory started from a Supernova. A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. They are 10 times brighter than our sun. The Universe will never stop expanding. It's actually expanding at rapid rate
Primordial Radiation is one of the strongest pieces of evidence in support of the Standard Hot Big Bang Model is the 2.7 degree Kelvin radiation seen in all directions A cosmic microwave background is the leftover residue of the Big Bang
Nuclear fusion is an atomic reaction in which multiple atoms combine to create a single, more massive atom. The Big Bang Combined lot's of atoms. Questions have appeared about will there ever be another big bang. No because the universe will never stop growing.
The law of conservation of Energy is a system that isolated from its surroundings, the total energy of the system is conserved. When the Big Bang happend energy was conserved.
