Not really, If scientist able to cover Matter/Atom into Light, it can able to do teleportation, think like fiber optic
PC data 1s and 0s, converted into light, travel thru a cable, convert back to 0s and 1s at the destination.
Same basic can do with Teleportation, unlike in anime or cartoon, a teleport machine convert human into light, then travel thru a cable just like internet, and arrived at the destination with another teleport machine and light converted back to human.
It is possible for this way to do it, but down side is that it light = travel in speed of light, if you want to get to 1 galaxy to another, it'll take many years. you may turn into skeleton bone or dust when you arrived, and is less advance then Darkdante's theory. But Darkdante's Theory is really really advanced, may take hundreds or thousand of years before it can really work.
OR you can do what NASA theory is saying, Go to the worm hole/black hole and see where you ended at the end of the tunnel. They believe worm hole is a warping device that bring you to 1 area in the universe to another.
The teleportation scientists are currently working on, is to "teleport" (read: deliver) information at the speed of light. It simply makes the light merge to be in the same quantum-state (not sure if that's the english words for it, though <.<) as the atoms, and then send that light in to another cloud of atoms, and make the light merge with the atoms again, so that they become the same state as the atoms in the other cloud, which can then be read binary. It doesn't actually teleport atoms, it simply transports its information with the help of light.
While its true that you can make energy in to matter and vice versa, no scientist currently know how you can turn energy in to matter, only the other way around. Sure, when they can manage to turn energy in to matter, it could, theoretically, be possible to transport matter to remote locations. However, it would not be possible to teleport them across the universe. Not only because it would take several life times just to get anywhere, but also for it to even be possible, you need to think of a way to send the information out to another place. Radio waves would be way too slow, and they're way too weak to send such complex information. It would also spread out over a too large area, further weakening the signal. Then you have a laser beam, which is just not possible. While yes, it is a focused, strong signal that could go on forever. But if
anything is in the way of it, it'll vanish and be unable to proceed forward.
Also, it wouldn't exactly teleport people. It would be a very advanced cloning technique.
Besides, even if you COULD find a way to teleport a human body by turning them in to light and then send them to a remote location, there's still one very hard obstacle to overcome. You'd need to rebuild one of the most fragile and advanced parts of the human body, with all of the trillions of brain cells and the billions of tiny nerves, exactly the way it was before. Otherwise that person could suffer serious memory loss, mental damage, handicaps, blindness, etc. And in worse case, brain death or death. Naturally, this isn't really anything scientists talk about, but I'm sure its one of the main reasons teleporting living animals is as close to impossible as you can get.
