It shows him grow a beard so he was obvious traveling in space for a long time. Does he breath in space, or is he just holding his breath, or we just going to pretend not to notice and just shut up and watch the show? I just started it and that’s asking the question b4 the show really started so if it’s answered then ignore my question. Thanks nerds.
A bigger issue I had was a) his cape looks like it’s flapping in a breeze whilst he’s in space, and b) he spends time observing a black hole up close. Time dilation that close to a super-massive black hole would mean that for him to have been gone for months on earth (as established in S2 ep 1) he’d have to have been in space for mere minutes in his perspective.
