       At galactic (or inter-galactic) distances, if faster-than-light travel is not instantaneous, then it's pointless. Travel will still not be feasible.#ScienceFiction

       @kaasbaas i suppose that depends on how faster than FTL it is.you could also have some kind of hypothetical exponential speedup that takes non-instantaneous time to get to, and requires non-instantaneous slowdown, but effectively collapses the time inbetween to instantaneousi'd be interested to know if there is a scifi universe wherein short distances are impossible because if a craft reaches FTL speeds it becomes unable to slow down quickly enough to not overshoot the planet. so if i wanna go earth to andromeda, that's fine, but if i wanna go earth to pluto it's a real goddamn problem.

       @trenchworms I don't know, if you start looking at how GD BIG it is out there, and start doing some math... Interstellar I can take. Intergalactic.. doubt.As for the slow-to-fast travel... well.Dune universe is kinda like that?

       @kaasbaas @trenchworms FTL travel is essentially time travel, that is, we are travelling either back in time or forwards, depending on your perspective. The Expeditionary Force series hit some problems around this, where it took advantage of time of light travel with light shells, but failed to account for the problems the time travel thing. FTL always hits this problem, and it kinda has to be managed somehow, usually it's ignored

       @roomey @kaasbaas Is space folding necessarily time travel? That is, at no point are you actually moving faster than light, there's just the impression that you are doing so. In the same way that me waving my hand through a super-powerful beam of light against a hypothetical wall millions of lightyears away could cast a shadow that appears to be moving FTL.

       @trenchworms @kaasbaas I'm not sure. I'm gonna have to think about it. lets say you are on plant A and look at planet B 1LY away. you see King Dennis die. You travel there by folding space. Is King Dennis alive or dead when you get there? What do you see when you look back at your home, are you still walking around there (as it is light from 1 year ago). Fold time and return, are there now two of you on planet a?

       @roomey @trenchworms don't confuse information traveling (at the speed of light) with the actual matter traveling (faster than light).eg - if you look at stars, we are viewing them as they were at some point in the past.IF you could travel there(ftl style), you will find the star in the state it is "now".So if you then jump back, at some point in the future you will be able to see yourself over there (assuming good enough telescope).But there is still only one of you hopping around
