<p>No UFO’s, but I think I work with some ET’s. I did see a very impressive meteor. I thought I would hear a big noise from the impact, but nothing. There was nothing on the news either, but since this occurred in southern Utah, I guess that was not surprising.</p>
<p>Scientists have always assumed that, based on what we know about the speed of light and the proportions of the universe (heck, of just the Milky Way Gallaxy) that there is no way extra terrestrials can have visited earth. But I’ve always wondered if it might just be a matter of us not YET knowing enough to make such an absolute determination. If it IS true that NOTHING can travel faster than the speed of light, and that alien travelers MUST use linear time/space methodologies in order to span the tremendous inter-galactic distances, then it makes sense to assume that we’ve not been visited by extraterrestrials. However, if technology exists which would enable an alien civilization to overcome these constraints (technology which we have yet to discover), than perhaps, some of the UFO stories are true. </p>
<p>As much as some people denigrate string theory (actually, M Theory) and it’s eleven dimensions as “psuedo-science”, there is a tremendous amount of legitimate research being funded on that front. If they are actually on to something, then maybe—just maybe—it might be available to travel inter-dimensionally, by-passing the conventional time/space constraints. The possibility of Parallel Universes is again being discussed as something other than junk science. I am, of course, posting this as a non-scientist, just someone who finds the “Alice-In-Wonderland” aspects of physics fascinating, and I was wondering what some of our resident “x-purts” 
think. </p>
<p>I’ve never seen anything remotely close to a UFO, but one day, I was making a rather derisive joke about them to my brother (who is a very serious and level-headed sort—musician, not into sci-fi, Star Trek, Star Wars, nothing of that sort—and he didn’t laugh. He looked at me quite seriously, and swore is saw a bonafide UFO a number of years ago. He told me the details of the account, and strangely enough, we’ve never discussed it again. I’ll have to call him and ask him about it again, because I’ve forgotten a lot of the details.</p>
