| Dec 30, 2021 at 21:22 | comment | added | Edouard | As this site caters to all education levels, I should point out that "flat" means lacking a net (overall) spatial curvature. | |
| Dec 30, 2021 at 21:11 | comment | added | Edouard | Spherical models (local universes such as our own "Universe", which includes both its horizon and the region of it that's visible to us) are currently appearing to be a more plausible possibility than flat ones, as seen at nature.com/articles/s41550-019-0906 . | |
| Dec 30, 2021 at 21:09 | comment | added | Edouard | In my comments on Motl's answer to this question, I'd been overlooking the basic problem involved, which is that the sort of vacuum fluctuations that might seem to make Boltzmann Brains (or, perhaps, local universes) possible would all require passage thru that single direction of time whose ongoing passage we sense as present reality, whereas Poincare recurrence would be indistinguishable from a return to previous points in time which we currently sense as past reality: Each of those possibilities necessarily excludes the other. The recurrence possibility's stronger in spherical models. | |
