I just was thinking for a while about how ****ing big the universe must be. I mean, where the hell does it end? Never? If it never ends how did the big bang create it, wouldn't that mean it's continuously creating more and more universe? WTF, I don't know. I mean it's gotta end somewhere right? Don't turn this into a religious thread either umkay? Just, damn i dont know where it ends...pissin me off....

scientists think that the universe is still expanding. we learned about it in physical science last year about the stars/galaxies moving away from us have a redish color to them. Stars/galaxies that are coming towards us have a bluish color to them...something like that...and i guess there are more red stars/galaxies than blue

Thats caused by the wavelengths given off by objects moving away are longer, which causes what is called red shift. Objects coming towards us give off shorter wave lengths and cause a blue shift.

Kind of like how a motorcycle sounds different when its going away than when its coming towards you

i read that the big bang created our GALAXY not the UNIVERSE. i don't think the universe ever ends i mean would there be like a wall? or mabye its round and we are acting like the europeans a long time ago and saying its flat.

they don't know if it even ends. Some theorize if u go far enough u curve back around on the other side.

Have u seen the interesting theory that might replace big band? It basically says that on the end of the universe is another one (or was it another demension?) less then 1mm away. And this other area bumped ours creating a random spread of energy etc.

yea thats it...red shift and blue shift...just like the doppler effect

thinking about the universe makes me feel too insignificant and makes us seem so.. pointless and useless. sigh.. I made myself sad.

i personally think the universe is like a 3D mobius strip of some sort. and black holes lead to the outside of nothingness, therefore anything that goes through turn to nothing.

if u dont know waht a mobius strip is then check out a very informational site:

www.google.com

The universe is NOT infinite. Space time is continually expanding, near the speed of light. Scientists have 3 theories of what will happen to the universe. First, the ever expanding universe or 'The Big Chill'. It states that the universe is continually expanding and will eventually reach absolute zero in temperature. Secondly is another big chill theory, where the expansion of the universe is accelerating, getting faster and faster.

Third is the idea of the Big Crunch. This theory believes that there is enough dark matter in the universe to gravitationally pull everything back into one mass, opening up the possibility for an Oscillating Big Bang Theory.

The most believed is the first, because scientists do not believe there is enough dark matter in the universe to have gravity be strong enough to stop expansion of spacetime, and contract it.


Random fact, everything in the universe used to be smaller than one proton.

no 1 theory is better than another until its proven.
my theory is that a giant half chicken half squirrel had sex with a purple bunny rabbit, which created the big bang.

my theory is just as good as the theory of relativity :D YAY
