So no matter how long the temporal sweet-spot, it is infinitesimal next to the entire Universe.
Okay, I think I understand that part; the time-window for life is relatively short and comparatively near the start time of the Universe, making it somewhat 'unique' or 'special'... yes?
Yet with the continuing and ever increasing expansion, the encroaching heat-death or cold-death will eventually be reached, and the Universe will remain in that state ad infinitum.
Suppose there were a way to enclose a biological system
and allow it to continue to function perpetually without the input of external energy potential, would this system still be able to exist after the heat-death/cold-death, or does the fact that it was built of particles from the expanding Universe mean that it too will expand and undergo the heat-death/cold-death extinction? I mean, is the expansion happening at even the most minute level, such that even
creating a biological system will be impossible after the heat-death/cold-death simply because the atomic structures required for such systems would no longer exist?
