mishamouse, i tooted out yesterday an off-hand comment about how i was enjoying #TheExpanse because they actually have to deal with things like g-forces (quite realistic compared to my usual #StarWars-style #SciFi), and it spawned a two-day long multi-branch conversation between at least a dozen people including (but not limited to) Bussard ramjets, fusion reactors, socio-economic analyses of science fiction politics, the list goes on.
the #fediverse is pretty great.
