You mentioned that we know that the universe is thousands of times larger than what we can see. We also know that the universe grew from a single point 13.77 billion years ago. Why doesn't that put an upper bound on what lies beyond the visible universe? "Behind" the CMB, so to speak.
It's a misnomer that the Universe started as a singularity. Only the observable Universe was once tiny. The actual Universe could have been infinite, even before inflation.
I've been enjoying "For All Mankind." In one episode the astronaut Molly Cobb descends into the darkness of Shakelton Crater. The show is generally quite good with being scientifically accurate, but wouldn't it be so cold that Molly's suit wouldn't be able to maintain temperature and she'd quickly become seriously hypothermic?
