i was reading an article today about the newest spiral galaxy photographed by the hubble telescope. it's called the pinwheel galaxy and it's gi-normous in that it's way larger than our milky way

pick up the new issue of scientific american. the whole magazine this month is dedicated to time. i was perusing through it last night at a friend's house. totally blew my mind.
well, i guess it depends on your definition of death. just because we can watch videos of elvis, that doesn't mean he is still alive does it? i mean, he is, but, not because of the videos. ;-)
hmm, good point. but if we were millions of years closer and the pinwheel galaxy had been blown up or something. knowing what we know of it. is it still in existence. intriguing minds...
galaxies don't exactly blow up to my knowledge. they do occasionally collide with other galaxies. what happens is they eventually stop making new stars and then once all the stars burn out, i guess that would be called a dead galaxy. but then again supernovas assure that the rebirthing process continues indefinitely. i'm not sure that astronomers have actually observed a 'dead' galaxy, but there are some that are so old that no new activity appears to be taking place. it's just a collection of matter right? these become kind of philosophical questions the further you go...
I believe the time continuum actually deals more with how time changes when you're traveling at (or close to) the speed of light...so, in theory, if you had a space ship leaving Earth and traveling at the speed of light, 75 years might pass here before it reaches it's destination...but the people on the ship will have experienced less years...I don't remember how many, exactly...you use the theory of relativity to figure that out...it's been years since I took an Optics course, so my memory could be wrong on all of this....
