# Thread: Scientists find most massive star ever discovered

1. Cosmologists often describe the expanding universe with the metaphor of a balloon - imagine the various galaxies as spots drawn on the surface of said balloon, and then gradually inflate it. Each of the 'galaxies' will move away from the others as the surface of the balloon expands; in this scenario, the balloon's surface is said to actually represent the 'fabric' of space/time.

Continuing the analogy, the universe, as represented by the surface of the balloon, would actually not have an end (if we consider the balloon's two dimensional surface to represent four-dimensional space/time); one could travel in any direction, never actually be any closer to any arbitrary 'center', and never reach an edge - although, arguably, if one could travel at impossible speeds, one might come around to the same place again, as if one were on a globe.

Now, as to how well that actually represents reality - well, analogies are always slippery, so who knows. As to your question - so scientists speculate on these things? You bet. What's the actual answer? Once again - who knows?

Fascinating stuff, though.

BTW, Todd - if I didn't say it before - good to see you back; you were missed.

That is amazing, indeed. You could travel as much as you want in the universe, but always arrive back to your starting point. Simply fascinating!

Thanks, bud!

It all depends on what you want to believe. Some believe the universe is infinite and flat because they did a test by creating a triangle in space and measuring it, if it was 180 then that meant it was flat and infinite which also means there are an infinite # of parallel universes to ours but they are simply so far away we will never see them.

Others say the universe is round like a bubble and its so massive and slightly curved that it looks flat to us like the bug on the balloon theory. With the round bubble theory they say that there are just a ton of bubbles out there all floating in something called hyper space which something containing all of these bubbles and each bubble has a universe in it. The bubbles can smash into each other creating new universes and spawning other ones.

Its really interesting about the parallel universes though, some say the parellel universes are so far away we will never see them. Others say they are right here, right now but we can't see them because they are in a different dimension. They are doing a test by smashing atoms together and seeing if the amount of energy put into the explosion will be less afterwards. If it is then that means something went into another dimension which would mean there are an infinite number of parallel universes going on right now in our world. If it does occur then we just need a way to get to that other dimension with a worm hole.

If the universe or "multiverse" as they call it is infinite that means there are an infinite number of copies of ourselves. If there is an infinite number of us that also means all possible outcomes happen will happen to our other copies. So that means there is another copy of us not SCI'ed (we were the unlucky copy)! But that also means there is a copy of us that is a serial killer, a copy of us that already died, a copy of us that was president, etc. Kinda cool to think about but really far out there but at the atom level its not that crazy. We are made up of particles and when we look deeper and deeper you can see electrons can be in more than 1 place at the same time so why can't we?

I like to think about these things because it makes me realize how little we all are in this massive place. It makes me feel less stressed about the day as well. One of my co-workers keeps a picture of the universe in his cube to remind himself this if he is getting stressed over a programming problem. What we do in this world is very insignificant if you look at the big picture.

All interesting theories. Some a bit frightening if you've ever seen Event Horizon.
