You want me to explain to you why nothing can go faster than the speed of light thru free space( Im talking about the vacuum of FREE SPACE (not a tube with gas in it, or a chilled magnet, or any sort of other labrotory manipulated experiment where the speed of light has been demonstated to be different) Maybe you never took phsyics in highschool. But it all has to do with Einsteins theory of relativity. E=mc^2, ever heard of that. This says as your speed increases, your mass increases, and the energy to make you go even faster increases as well. So, E=mc^2 says that as you approach the speed of light, your mass becomes infinite, which is impossible, and the speed that would be required to push you beyond the speed of light is greater than the energy that exists in the universe. Also, to an observer, if you could travel faster than the speed of light, you would appear to arrive before you even left, which is impossible.
The reason aliens would use the Electromagnetic spectrum (waves) to commuicate with is because they travel at the speed of light, and nothing is faster than the speed of light (see above). You cannot create some sort of faster wave, or manipulate it while it travels thru free space. I would be willing to say MAYBE in an extremely ADVANCED civilization, some other means of communication might be achieved, i cant imagine one, but i am willing to imagine....BUT....they would have to, at some point in their evolution recognise the advantage of the electromagnetic spectum for communication, and many other uses, before they invented their amazingly new way of communication that we cant possibily imagine.
