Because it's expanding

Lou Gutman, P.I.- It's like I'm not even trying anymore!

One billion b-balls dribbling simultaneously throughout the galaxy. One trillion b-balls being slam dunked through a hoop throughout the galaxy. I can feel every single b-ball that has ever existed at my fingertips. I can feel their collective knowledge channeling through my viens. Every jumpshot, every rebound and three-pointer, every layup, dunk, and free throw. I am there.

Why is the colour of infinity blue?

It has made me the man I am today. A man who craves furry hentai.

So let us go and embrace the rustling smells of unseen worlds

Olber's Paradox (named after Heinrich Wilhelm Olbers)


Finite age of the universe


This explanation of the paradox points to the finite speed at which light travels through space. As we look further out in space we see further back in history; eventually we would pass beyond the finite age of the universe. A similar explanation was first offered, ironically, by poet and writer Edgar Allan Poe in his prose poem Eureka




While the finite age of the universe deals with the contribution of stars to the brightness of the night sky, it leads to the question of why the Big Bang itself does not visibly contribute instead. The reason is that the radiation from the Big Bang has been redshifted to microwave wavelengths as a result of the cosmic expansion, and forms the cosmic microwave background radiation. The expansion of the universe also limits the size of the observable universe, which means that light beyond this does not reach us, which creates the optical effect of living in a finite universe (see finite age argument).

What don't you understand, Bok?


If the universe is infinite, then there should be stars in every direction (distance is irrelevant, except to work out time, but we'll get to that later).


If there are stars in every direction, then there should be light in every direction. Right?


The only reason that there isn't light in every direction is that the universe isn't old enough: in an infinite amount of time, the sky will be white with light because there WILL be stars in every direction. :)

Unless it suffers a cold death (expands too fast for gravity to pull it all back into another crunch).


And we still don't know if Dark Matter and Dark Energy really DO make up 75% of the mass of the universe. :)


I'm no scientist, but nearly everything observeable is cyclical in nature. I can't imagine why the universe itself would be different.

"Of course the people don't want war. But after all, it's the leaders of the country who determine the policy, and it's always a simple matter to drag the people along whether it's a democracy, a fascist dictatorship, or a parliament, or a communist dictatorship. Voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism, and exposing the country to greater danger."

I though the universe had reached it's full expansion and was starting to slowly shrink again.




Nope. Too much redshift on the farthest galaxies.



We can look forward to the Andromeda galaxy colliding with ours though! :sorcerer:
