Would this allow you to communicate over light years instantly?

No such thing. It's all made of particles held together primarily by electromagnetic forces.
Guess how these particles communicate to each other. Photons.
So no, it would communicate at about the speed of light...probably a little less.
This is the crux right here....information (meaning anything...any sortof of particle) CAN NOT in any known way travel faster than the speed of light. It just can not happen. If something is massless it can...at best...move at the speed of light.

Well...in 100 years theres never been an experiment to contradict it...so...you're setting yourself up for dissapointment =)

those are the key words... i truly believe that travel faster then the speed of light will be achieved eventually. then again, im also certifiably off my rocker.

Doesn't quantum entanglement suggest that information could travel faster than light? Even Einstein and other relativists say that data could be sent through a wormhole, given enough energy to produce a stable one.
Raymond Chiao says you can (kind of)
But as far as I know, you can't do it in a vacuum, but this may make computers transfer info within themselves faster.

Correct me if I'm wrong, but you aren't really moving faster than light in a wormhole. You are just bringing your destination closer to you.

It's not breaking the rules, if that's what you mean.
But for people that are seperated by a galaxy or more, for all intents and purposes, that info traveled much faster than if carried by energy over the distance.
Still doesn't quite explain how entanglement works though.

Nah, I was just getting at you don't need to travel faster than light to get around. All we have to do is master that whole "gravity" thing but that shouldn't take too long.
The physical standing of "information" is a funny thing. It's been known for some time that the collapse of the wavefunction is instantaneous, but no one asserts that it breaks any laws since no "thing" goes from point A to point B faster than light.The Shadow said:
Consider this simple experiment. Take a candle, place it some distance from a wall, but not so far away that you can't make out a shadow clearly. Now, pass your finger in front of the candle -- you should notice that the speed of the shadow along the wall is much faster than the speed of your finger because of the distance. Now, let's say you have a very powerful source of light -- say, a star -- and at some arbitrarily long distance away, you have a viewing screen. It's possible to set up some combination of distance from star to screen and speed of an object passing front of the star to make the shadow move arbitrarily fast...faster than the speed of light, in fact. But what kind of "thing" is a shadow? There isn't anything there -- it's simply an absence of light, which is non-physical. The photons which illuminate the screen have all obeyed the laws of physics perfectly.
