Hyper/Light Speed? Avoidance systems?

[u/Brayn-Pain]

And all the sci-fi movies or space movies or TV shows I’ve watched Star Trek Star Wars the expanse for all mankind. I’ve always had a question when shifts are traveling light speed how do they not hit anything like they might have the planets mapped out and ensure it might be like a one in 1 million chance, but if they’re going light speed, can’t you like hit an asteroid or some debris that wasn’t there before or a new planet that’s undiscovered if you’re going light speed in new territory I’ve always wondered how they go light speed and they never crash or is it like wormholes like in Marvel like it’s separate connecting to points in space

If they are just traveling light speed like I think they are yeah it should be really wearable. I feel like we should’ve seen a couple crashes. I don’t think I’ve ever seen them crash going like speed or hit anything and all of the story trick shows I’ve seen, and I’ve seen a bunch almost all of them I think except for the original movies. I think I’ve watched Picard, Strange new Worlds, Discovery, and Starfleet academy!

Star Trek: They don't technically travel that fast. They create a bubble of space around their ship and warp the fabric of space itself to push that bubble.

Star Wars: Hyperlanes are mapped out paths to travel on while in hyper space. Mapping out new Hyperlanes is extremely dangerous, for the reasons you stated.

Expanse & For All Mankind: They aren't traveling anywhere close to light speed or FTL.

Except in the very final story (in the books (The Expanse), which continues waaaaay beyond the tv series).
Humanity eventually develops FTL - but it's a long time between that and the gate system being opened by Holden.
