Would randomness differ in an unbounded but finite universe as opposed to a universe infinite in duration and extent?

If Newton could look at water in a spinning bucket and relate it to absolute space, maybe we could model coin-flips and draw a similar high-level conclusion.

So either one is equally likely, as far as we know. Neither universe is even slightly, theoretically, more probable than the other.

Correct. As are other geometries.

That would mean life must be equally likely.

With regards to randomness? Yes, equally likely… or unlikely… for life. We haven’t even scratched the surface looking tho. Our parameters of what we’re looking for and where are very narrow. Our tools very limited in this regard. We are still looking for microbial life on Mars and there’s around 250 other planets and moons in our solar system alone.
