Just a question that I wonder if anyone has a logical answer to lol
They say that it takes millions of light years for a stars light to reach earth for us to be able to see it, so how do we know its actually still there??? at this current moment in time, ummm does that make sense lol
Thats the thing about time - its all relative to your position in the universe. If a star is only say- four light years away, then any change would be noticable in that shorter period- the thing is because of how we percieve things, the light that we see coming from a star may as well be coming from ten minutes ago rather than ten centuries ago - to us it makes no difference.
Time is simply something mankind thought up to lessen the enormity of the universe and to pinpoint our place in it a little more accurately- even the light from Sol - our closest star - takes nine minutes to reach us, but because its pretty constant we never get to experience any delay or loss of light. Even during an eclipse, but how would we know if it did get interrupted at the source- unless one was actually there?
Every now and then stars explode- but it still takes the same time for the light to reach us.
Remember- "The Universe is big..Really big.."
:grin:
lol thats a bummer really cuz if you found life 10 light years away and both parties agree contact, we take off get there an there is nothing there. Turn around and come back and earth is no longer there. That can make for some pissed off explorers lol. The ultimate stand up rofl
If you're into good science fiction Carl Sagans book Contact has a lot to say about this kind of thing..
......and there is always the question, "Is time linear?" That in itself makes a complex question even more so.... ???
I always remember biology told me to have life you need these things and I pissed my biology teacher off cuz I kept asking "how do we know thats true".
he kept saying because of this and that and I said "if things adapt why can they not adapt to other things' he said it did not work that way.
Only to prove years latter that I was right and he was wrong lol
I check it in the shower.
