Would a wormhole be considered a rip in space-time since in essence it travels things through time since nothing can move faster than light, and it would be getting something somewhere faster than light? And isn't that suppose to be impossible? So doesold theory have to be rethought or am I completely off? Seriously, I'm not that educated on the subject.

a worm hole is a short cut through space

take for instance this example you are you and you are on foot, i am me and am in my brand new 2005 porshe carrera gt

we are going to have a race from 1st street to 4th street, because i am in a car i can only travel on the streets, but because you are on foot you can cut through yards, when that light turns green for us to begin, all you have to do is run through 4 back yards and you've beat me, i still have to travel the 4 blocks, time is the same, only the distance has changed

the same thing for wormholes, lets say you are you and you are in a space shuttle and lets say i am me but i am now a photon of light, we are headed from alpha centari(nearest star to earth besides the sun) back to earth, when its time for us to go and begin the race i have for light years a head of me before i reach earth, but if you fly through a worm hole you may get there in 4 days, maybe 4 minutes, maybe 4 seconds depending on how big the worm hole is, while traveling through the worm hole you are not exeeding light speed but because your distance is so much shorter than mine, you will reach earth before me...no matter how fast i may be traveling


hope that helps you out...any questions, or if you need me to clear anything up please ask

Go faster than light, and you could return before you've left. Pretty amazing ain't it and if I am not mistaken blazing Speed is faster than speed of light.

Wormholes are just theoretical constructs at this point. Being able to move faster than light through a wormhole or any other means would violate causality. Faster than light travel is basically the same thing as time travel, and impossible according to relativity. Plus, in theory wormholes would require negative mass - a lot of it, and it's not even known if negative mass is possible.

yes, but what about what seeking just said about it being simply a shortcut, not travelling faster than light?

faster than light travel is not the only way to time travel, faster than light travel would allow you to travel back in time, but you can still travel foward in time by moving near the soeed of light, basically you dont have to travel faster than light to travel in time, time travel is also not impossible, it is possible theoretically, only we dont have the technology to achieve it at this day and age, also wormholes are just an idea at the moment like you've said however womeholes only require exotic matter to keep them open long enough for one to travel through, they can form on there own with out the exotic matter but there would be no telling how long it would stay open

So, they're not a rip in space-time?

A lot of people know that relativity forbids objects from being accelerated faster than light because of the infinite energy requirements involved, but some are not aware that FTL travel also violates causality, which is more fundamental. Wormholes, "warp drives" and other clever ways of getting around the light speed barrier do not address causality.

I'm really no good at explaining this stuff. You have to understand light cones, inertial frames and some other esoteric concepts. Basically, a signal the moved faster than light could end up being recieved before it was sent.

But as Seeking pointed out you can have a sort of time travel to the future by traveling at relativistic speeds - this is the time dilation effect predicted by special relativity, and confirmed experimentally.

For faster than light travel to be possible though, we would have to discover new principles of physics.

Watch the movie Event Horizon
it;s a cool movie about worholes and what culd happen if you got lost inside one

that be crazy to go back in time. o.o
