Is it possible?
People have talked about UFOs for as long as I can remember. I would love to believe in them, looking up into the night sky and trying to get my head around the distances involved is also something I've done for as long as I can remember.
Scientists have always said that traveling faster than the speed of light is a basic impossibility. Has this changed? Is there any hypothetical, scientifically plausible way that could move a space ship at faster than light speed, or is the speed of light still an absolute barrier?
