What is the theory of the big crunch? According to this theory, the universe will one day stop expanding.
Then, as gravity pulls on the matter, the universe will begin to contract, falling inward until it has collapsed back into a super-hot, super-dense singularity.Sep 28, 2023.
Scientists theorized that gravity would eventually slow and possibly even completely reverse this expansion.
If the universe had enough matter in it, gravity would overcome the expansion, and the universe would collapse in a fiery “big crunch.”.
While the Big Crunch used to be a widely accepted proposal for the end of the universe, evidence came out in 1998 that made it seem far more unlikely.
By studying the brightest type of supernova explosions, known as type 1a supernovas, it was discovered that the expansion of the universe was actually accelerating..
Our cosmos' final fate is a long and frigid affair that astronomers call the Big Freeze, or Big Chill.
It's a fitting description for the day when all heat and energy is evenly spread over incomprehensibly vast distances.
At this point, the universe's final temperature will hover just above absolute zero..
Oscillating Universe Theory
The Big Crunch occurs when the universe expands and eventually reverses, then collapses causing a singularity or the formation of another Big Bang..
The Big Crunch theory that predicts how the universe will end is yet another scientific thing the Quran details.
The idea based on Einstein's general relativity theory talks about how the universe that began with the big bang will be eventually destroyed as its consequence..
A closed universe (Ω \x26gt; 1), lacking the repulsive effect of dark energy, gravity eventually stops the expansion of the universe, after which it starts to contract until all matter in the universe collapses to a final singularity, "Big Crunch"..
For scientists to predict with certainty the possibility of a Big Crunch, they will have to determine certain properties of the Universe.
One of them is its density.
It is believed that if the density is larger than a certain value, known as the critical density, an eventual collapse is highly possible.
One such theory, concerning the future of the universe, is playfully known as the "big crunch." According to this theory, the universe will one day stop expanding.
Then, as gravity pulls on the matter, the universe will begin to contract, falling inward until it has collapsed back into a super-hot, super-dense singularity.
Just like many others, it is based on Einstein’s Theory of General Relativity.
That is, if the Big Bang describes how the Universe most possibly began, the Big Crunch describes how it will end as a consequence of that beginning.
It tells us that the Universe’s expansion, which is due to the Big Bang, will not continue forever.
