No the universe isn't heading into a big crunch because there's nothing for our universe to crunch into. Our universe is never ending so there's no room for anything else. But some people believe that one day a dimentional shift may occur and our universe will collide with an alternate on creating disaster but our universe won't be heading into a big crunch but our galaxy is heading strait towards M31 which is another galaxy billions of light years away the two galaxies will collide and we might end up with some more planets and the gravitational pull will change because of the collision.

Peter. The Big Crunch.
No. Universe A expands from a 'Big Bang' stops expanding, and contracts until there is a 'Big Crunch'. Then there is a new big bang and the beginning of Universe B, a middle, and another big crunch, a big bang with Universe C and so on. At the time of any 'big crunch', all matter and energy from that universe ceases to exist. It cannot manifest itself until after the next 'big bang', and then has no relation to anything in its previous manifestation.
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.
There may be at some point near the end of the universe, if the whole universe does the opposite of the Big Bang. Should the universe implode into one big mass in what we call the Big Crunch, another Big Bang could follow. Humans may not experience this because as it stands now, when our Sun dies, Earth dies. Additionally, nothing we know of could survive the Big Crunch.
The Big Crunch is the opposite of the Big Bang. It will occur if there is enough matter in the Universe to slow down and reverse it's present expansion. Rather than constantly expanding, everything already in place will come together. That can't be a good thing...
Closed: Is where there is sufficient gravity to halt the expansion of the universe, after which is slowly starts to contract until "The Big Crunch".
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.
It *MIGHT*. However, all present observational evidence is that our Universe will not fall back into itself, meaning our Universe will not experience a Big Crunch. As observations and theory develop in the future, we MIGHT conclude differently. Or we might not. Predicting scientific discoveries is not (dare I say it?) an exact science.
These are interesting conjectures, but there is no way to determine if any of them have any validity. My own favorite unprovable hypothesis is the Big Bang/Big Crunch of a cyclical universe; everything in the universe eventually falls together in a Big Crunch, reaching infinite density, and a rebound effect causes the collapsed universe to explode into a new Big Bang - to be followed some uncounted billions of years later by another Big Crunch. There's no way to prove - or to disprove - this idea, either. The truth is, for now, we do not have enough information to determine what the origin of the universe is, or what the ultimate fate of the universe will be. We may NEVER know these things.
For starters, the universe was formed from a big bang not crunch.When the big bang happened a bunch of rocks and gases were in space.The rocks and gases then clumped together and then planets were formed.
1. the universe continues to keep expanding 2. the universe slowly stops expanding 3. big crunch (basically the universe will stop expanding and fall back into itself)
yes it states that the universe will stop expanding and start crunching back up to a state before the big bang
