I recently read that:
What our current level of thermodynamics does tell us though is that if there is such a thing as a Big Crunch, the universe will look a lot different as it heads towards collapse than it did when expanding – the universe started in a state of low entropy and high order and will end in a state of high entropy and low order.
But shouldn't the order be in a high state and hence entropy becomes a low state in the Big Crunch (assuming a closed universe)?
The reason I write this is because the gravitational forces in a closed universe are so strong they will cause gravitational collapse so the universe will shrink and go backwards, eventually through all the stages of the big bang and become a singularity once more.
It was my understanding that a singularity has a state of high order and low entropy. Have I got this the wrong way round?
If so; Can someone please explain why?
