Those are all really interesting factors to consider and I appreciate the response!

I'll come clean, when I wrote it, I was just making a funny, like... A "decaying vacuum" would suck less over time. . .than a black hole. Lol XD

To your point though, less likelihood of finding other life is such a wildcard, for sure. (Less likelihood of meeting cool benevolent spacefarers...but also less likely to be spotted by something like Mass Effect's Reapers, or accidentally bring home Xenomorphs or extragalactic pathogens lol)

And...not being able to ever see the beginning of everything...my curious mind says that'd be such a bummer but also...oddly beautiful? I'll have to ponder that...
