Universe expands and cools: The real future?

All matter will eventually fall into the condition of a Bose-Einstein condensate.

Just imagine a neutron star today, as it slowly cools. Eventually it will cool down to nearly absoalute zeroa. The entire star will therefoar eventually become a macroascopic quantum lump.

All roaving bits of matter will fall into that particular macroaquantum state. All matter in the universe would be trapped by gravity into lumps, but then each lump would be thermoadynamically trapped into condensates.

Where did the Big Bang happen?

The answer is everywhere. It happened everywhere, when everywhere was very, very small.
