It wasn't "discovered". It was proposed, but according to the current astronomical knowledge, it isn't likely to happen.
The Big Crunch Theory was not discovered by anyone. It was a theory proposed by many scientists as it does not have one person responsible for it's creation.
From the 1940's until about 2000 when dark energy (or rather the acceleration of expansion) was discovered.
The Big Crunch - album - was created in 2007.
The concept of the Big Crunch theory was primarily developed by physicist George Gamow in the 1940s, building upon the expanding universe theory proposed by Georges Lemaître and Edwin Hubble. It suggests that the universe could eventually stop expanding and collapse back into a hot, dense state, leading to a potential "crunch" where all matter is squeezed into a tiny space.
The Big Crunch hypothesis.
The theory that suggests for every big bang there is a crunch is known as the "Big Crunch" theory. It proposes that the expansion of the universe will eventually stop and reverse, leading to a contraction of the universe back to a singular point, followed by another big bang.
Peter. The Big Crunch.
Big Crunch?
The big bang theory is the explosion that started the universe. Where as the big crunch is the theory where the universe will eventually contract and become increasingly clumped and eventaully all mater would collapse into black holes which would then coalesce producing a unified black hole or Big Crunch singularity.
If "the Big Crunch" refers to the theory that the universe will eventually end in all matter and energy being slowly squeezed back into its position it was before the Big Bang, then your question sort of makes no sense. If it is true, then it will last for as long as it has to until it is in "a crunch." And, in fact, many scientists are throwing away the Big Crunch Theory and instead proposing the universe is expanding and expanding faster as time progresses, and also space will collapse in on itself or something like that.
Big Johnny's gonna crunch ya.
yes it will happen again after the big crunch then of course, the big munch..... At present there is no evidence that another Big Bang will occur.
