What is the super cell of galaxies and what is the super wall I heard of recently?
Where does the universe end? or does it end? If it ends what is the rest of the universe? Also if we think our Universe is endless and it is not wouldn't the known universe be smaller than we could possiblly imagine.
Just trying to pick some peoples brains for data and philosphy on science, god and the universe.

Cosmic background radiation is what is believe to be the residual energy from the big bang. The theory is that at the moment of the big bang huge amount of energy is release and for the most part they are evenly spread out. And after 15 billion years the expansion of the universe cause the radiation to lose energy and right now it is about 3K.
On a small scale the radiation is not even, but instead slightly clustered. Which it is believe oh what cause matter and galaxies to from. The cluster of energy, therefore mass (since mass can be formed from energy) will expert more gravitational force then more spread out area of energy. This allows for the eventual formation of galaxies, nebula, and stars.
Its been found that galaxies form clusters and walls, with voids in between the clusters.

Some people say that the CBR is like an evidence of the big bang..if it was an explosion then we should be able to find the evidence of it, and the CBR would be like the afterglow of the big bang ..it's not uniform along the universe though, so I don't know about it...the ¨great wall¨or super wall is a bunch of galaxies that two astrophysicists found in 1990 , I don't know exactly the dimentions of it ..like 200 million of light years long or wide or something , but anyway is huge; and after that they had found groups of galaxies even biggers :/
..that says that the BCR shouldn't be so uniform after all and, well you can always fixed those problems, sometimes you can always do some corrections to your theory and that's it, so
that shouldn't be much problem if is not for the fact that these galaxies move slowly, realtive to one another, that somehow indicates that in their formation they may have taken lots of years BEFORE the big bang ..funny huh?
I don't know, who ¨really¨ can say that they know this stuff? :/

Universe doesn't end.
