Watching prof Cox The other night. The universe reaches entropy in a trillion trillion trillion trillion blah blah blah number of years. So big is this number that if you counted every atom in the universe you would run out of atoms before you reach this number. The last lights of black dwarf stars go out and a sea of photons remains for infinity.
The truly interesting but is that the stars required to support life go out after a billionth of a billionth of a billionth blah blah blah of one percent of this time. We are only at the beginning of that very small percentage. All the big white stars will be done within this small time.
We live in the best time that the universe has to offer.
