I know a Green Lantern can travel through space, but how exactly do they do this (i.e. wormholes, warp, hyperspace, etc.)? I mean they have to be able to move at faster then light speeds to move farther then a light year right and if they can use their rings to move at FTL speeds then have they ever used this ability in combat?

I believe it has to entering some sort of hyper/warp-space, but I'd love to know (for sure) also.

In order to traverse the galaxy, yes they'd need FTL speeds, and matching reflexes so they don't crash into asteroids.

They pretty much have to be

Reflexes and combat speed would be something the rings probably couldn't influence. They can only think so fast. What does fighting at FTL speeds really mean though?

Actually they have to be a lot FLT since at light speed it'd probably take a few thousand years to get from Earth to Oa

I'd be interested to hear an explanation on how GLs keep their body from getting crushed when they enter FTL speeds considering mass gets more concentrated the faster it moves.

They don't have to.

The DC Universe is small.

Every other planet is some kilometers in distance away from eachother.

I think it's hyperspace

One good thing about the rings, is you can basically just say "it's magic". And I don't mean that it's a cop-out. The energy is supposed to be refined from the magical energy of the star-heart (or w/e...that part of GL history is convoluted in my brain) and comics say magic is just energy science can't explain/understand yet....so there's not a lot of need to explain how the rings (/energy) can accomplish what they can.

Maybe Green Lanterns only pretend to fly fast but they actually cheat and just teleport.

@Pokeysteve: The would require near FLT reflexes to avoid slamming into planets, asteroids and other stuff that tends to move around in space. That awesome power ring doesn't mean anything if you hit rock at a few million miles per second

I've always thought they could travel FTL.

To be frank, no one should be able to move Ftl.

I was under the impression the Green Lanterns got from their sector to Oa and back again via some-kind of portal or hyperspace flight, but can only go those distances.

it can be said that they can move and fight pretty quickly if they can will themselves to do it, as if to augment their physical abilities, but, this isn't seen very often in comparison to the use of constructs.

Surprising no one has found some scan of it being described. I'm pretty sure I remember it being mentioned in pre-52 GL or GLC (but that's a ton of issues to skim through with no idea where to start).

They should be able to.

Wow, those rings are even cooler than I thought if they enable FTL speed.

Those rings are like miracle machines maybe.

I've been reading the Sinestro Corps crossover and from what I've read they fly though something called trans-luminal space. They don't really get into specifics about it.

Also I looked this up on a few threads where fans asked the same question. Here are some of the answers I found...

BTW, any green lantern can travel faster than flash. Flash is limited to the speed of light, wheras a GL can trave across the entire universe within a matter of days or less.
