You thought you were rid of me. Sorry, Charlie's still on vacation for a few more days, so here's something that has nothing to do with current politics. Just to be annoying, I'm going to revisit that ever-giving fount of joy, slower than light (STL) interstellar travel. You may think that, because it's not physically impossible, that it's inevitable that humans will travel this way one day. Sadly, it looks like blasting your way between the stars the hard way requires magical technology too, just as FTL does.
We've talked about this before on the blog, but unfortunately, the really good conversation was about 800 comments in and about 8 (?) years ago, so you can't just google it. Here, I'm going to cover two points: why canned monkeys don't ship well, and what the precursors to STL would look like, so that we'll know if our society ever starts preparing itself to expand into space at less than the speed of light.
