Well In my science book it says that the universe with all the gasses and stuff in it went and started gathering at a central point about 13billion years ago...And well
what doesn't make sense it that the gasses came together in space with by definiton is a void of nothing...tell me this how can something be created out of nothing?
I think thats why people believe that there is a "god" or supreme being that created everything and has a plan for everything
Me personally I'm kinda liking the Men In Black theory atm
am i a little late to this thread? =)
i just have one thing to add to this question: we dont even know what space is, so i would say we dont have a real definit anwer to what "space" is. space is not "by definition" empty. einstein in his early work with general relativity stumbled upon what is called a cosmlogical constant. this is something that permiates all space. therefor space itself can be used as a reference for motion, more specifically accelerated motion.
the ideas you hold about space are what we trhought a VERY long time ago but were all found to be false. space is not just a big stage within which events happen. space is a very 'real' and 'alive' i guess you could say.
no one can tell you a specific answer, and there has always been something, be it god or the physical material. but a theory that has become pretty established is expansionary cosmology.
the cyclical cosmoligical theories have all pretty much been debunked so you dont have to worry about the universe collapsing, the more realistic alternative would be that everything floats away from everything else until we are very very alone (but humans would be gone way before this happens).
but the more we measure, the more we think that there is just the right amount of mass/energy in the universe that attractive and repulsive gravity will eventualy balance out.
i didnt read through all 60 pages of this so sorry if any of this has been covered.
and i dont remember who said it, but it was in the first or second page. something about how our old pictures could be tricking us into thinking there was a begining. could you explaint that more?
oh and to RacecaR (the guy on the first page that said to read the brian greene book angels and deamons): STFU NEWB!
