Don Firth uh, Vega is Lyrae alpha, Aldebaran is Hyades alpha. Yes we are moving toward Vega which will become our "pole" star in another 13,000 years or so but our mean distance from the central black hole apparently stays pretty much the same due to orbital influences.

As relativity implies, the view is always subjective. Whatever the viewer's norm is, that is, his stiz em leben, his planet, etc. seem motionless. It's everything else that moves.

A lightwave IS weightless and a photon has mass, what? of one electron? Sadly, when you get to the subject of light itself all those neat little perks of Special Relativity go right out the window. If you stand on the right with your light saber and I on the left (wait! I think I have that backwards!) and we simultaneously flip the switches, your light is traveling toward me at 186,272 and some odd miles per second and my light is taveling toward you at the same rate, the first few photons which encounter each other do so at, a-hem, 186,272 and some odd miles per second. That's all it ever will be (max) although, as pointed out above we have been able to slow the non-stuff down to an almost zero progression.

But that's not so amazing when you stop to think of the relativistic games light is playing on all of us all the time. It speical relativity holds true, when that one photon meets another photon ( a comin' through the rye?) they see each other as stopped dead in their tracks, possessing all mass, infinite gravity (which is to say infinite energy) and the universe seems to still be in the infinite infintessimal stage as it was before the Big Bang! And so it may be, in another dimension as nothing say that light has to be solely in our observable universe. This might go a long way into explaining de'ja vu'. Here, have an extra apostrophe'!
