A Fediverse community for open-ended, thought provoking questions
Please don't post about US Politics. If you need to do this, try !politicaldiscussion@lemmy.world
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
Reminder: The terms of service apply here too.

A lot of depictions of teleportation seem to imply that you instantaneously move between two distinct points in space without having moved through the intervening matter - if that's the case you have to deal with a whole lot of complexity to ensure that you are moving at an appropriate speed at your destination - it depends a lot on your reference point, but imagine teleporting from the equator to the north pole without accounting for the difference in velocity of the ground due to the earth being a sphere. If you were standing still on the equator but preserved your momentum through the jump, you'd be moving at 1600km/h when you arrived. Air friction and the sonic boom alone would mess you up, let alone if you collided with something.
You are right, you could solve it by having the teleportation move you through some sort of hyperspace and making the jump almost instantaneous so you have time to accelerate and decelerate, but even then you'd need to hand wave away where the energy goes. Imagine the same set up, you've accelerated through hyperspace towards the pole, then decelerated back down to end up going 1600km/h slower than you started. For an average person this is about 8 MJ of excess kinetic energy that has to go somewhere
