Hello, I know I'm just full of silly ideas, but afterall this is the physics forums, and I happen to have lots of questions :P. So, basically what I'm interested in, as the topic suggests, light speed internet. Now now, I know many of you would respond with, "its been done --fiber optics!!". However, what about sending information on light waves rather than through fibers? What setbacks has there been? Does it all come down to when observed the wave collapses thus distorting the information?? Or have we simply not figured out how to modulize the information? I looked through here and a few other places before posting, but there were really no informative answers.
