# What happens at the end of entropy?

If all the matter in the universe is eventually headed towards dis-integration into it's most basic form. Not sure what that is but for this thought experiment, let's say its single protons.

What would happen if all those protons formed a single mass? Would that be a singularity exhibiting no entropy? Does entropy lead to an eventual re-integration of all matter into one common form?

The most widely accepted idea is that the Universe will continue to expand until every particle is too far away from other particles for any interactions to occur.

That is the maximum entropy state, thermodynamic equilibrium.
If you somehow could push the bits back together so that interactions can occur again, the act of doing so would reduce the entropy of the Universe.
It no longer is at maximum.
That can't be done of course because it would require something external to the Universe to accomplish the feat.

Ok so the big bang is the point at which entropy begins within the most highly organized state matter has ever or could ever exist? and that was what, a super massive super dense orb? or was it so organized and compact that it was tiny? and existed in a single point the size of a Planck?

The big bang theory does not attempt to describe an initial state of the Universe.
Whatever it was though, it was 'singular', there is only one possible state that it could exist in.
It gets worse, there could be NO possible states.
When math produces conclusions like that, it means our theories need working on.
