Here’s the good news: scientists think they figured out how they can see inside a black hole.
Bad news: they still haven’t figured out what’s in there, where they go, or how to get out.
The question I present to you, dear writer, is does it matter? If we have two ends of a black hole that suck things in, is there really an out? Wormhole shortcuts through spacetime are what writers and scientists and geeks of all kinds have dreamt about for a long time, but we really have no idea. Have scientists ever seen event horizons that appear to push things out? A quick Google search calls such things a white hole, and these are even more esoteric. If there was an out, wouldn’t we see at least one somewhere? According to the Wikipedia link above, we’ve never seen anything resembling an out. I dunno. I’m just an editor and writer. It seems like a good story bit, though…
