Total entropy with the universe gradually cooling down but never reaching absolute zero.
And then, when everything, everywhere is exactly the same and time and space have no meaning the whole thing might just explode (and I use that word quite wrongly) again!
The expansion never stops, each particle finds itself more and more alone. Quadrillions of lightyears will separate even the closest pair of particles left, and the expansion continues relentlessly.
So too the temperature. Closer and closer to absolute zero. And it turns out, matter when cooled enough forms a Bose Einstein condensate, and due to quantum effects, the particles location becomes more and more indefinite. Essentially, get matter cold enough, and it erases itself over a larger and larger volume.
