I'm assuming that the observer witnesses all other particles enter a horizon, be it an event horizon or the particle horizon. Thus the observer's observable universe would contain himself only. Is this understanding correct and can it happen in finite time? Also does such a universe have time (maximum entropy is achieved).

Forces hold stuff together, Edward. Depending on relative magnitudes, a galaxy like our Milky Way might remain intact.

EDIT: Assuming that proton decay is real. However if Proton decay is not real, can heat death be achieved in our Milky Galaxy, even as time elapsed goes to infinity? Or after a finite amount of time the Milky Way would be very cold but due to the Third Law of Thermodynamics, never reaches absolute zero (and thus there is always observable motion). Thus the Second Law predicts heath death, but the third law makes it asymptotic.

What idea do you have in mind with respect to cosmological curvature? This looks like slapping the 'truth' out of a tuna to me.
