star dust

this discussion could be be happening all over the universe by loads of humanoid type creatures... weird.

at the moment there isn't enough matter acounted for in the universe to create the strong forces of gravity needed for the "big Crunch" to occur, and so consequently it may not even happen and the universe continue to expand (steady state theory) however i dont believe this. Dark matter must exsist in our universe somewhere...matter sucked into a black hole for instance, whole galaxies could have imploded in on themselves way back when the universe was "born". thats just my thoughts...

i think it must end somewhere otherwise how could it be expanding?? What would it be expanding into?

they are so pretty and amazing, its hard to comprehend that they are actually out there in our universe somewhere!

isn't a planet made because it didn't have enough energy to carry out Nuclear Fusion, like a star does?

that actually answered a lot of questions that i had been pondering on. Thanks!

wouldn't we in some way or another feel that effects of the black hole that is parallel to our Sun, if your theory was correct?

has this actually been scientifically proven??? or is it just a theory?

hello. i'm new to this site and i have a very passionate interest in cosmology. however there is one thing that i cannot get my head around. The universe is defined as all time, space and matter. everything. If the universe is expanding, then what is it expanding in to, because technically it would be the universe anyway...
