There HAS to be other life in the galaxy/universe besides on Earth.
What makes up an electron, proton, or neutron? I think quarks make up protons. Then what makes up quarks? Then what makes up those particles?

Well if the universe was shaped like a map and it was spread out as a 2D piece of paper then yea you would end up never reaching the end but going in a constant loop. If the universe is a globe type figure then would you ever reach the "end"? Is there an edge of space? Does space go on forever?
Is the big bang what we think it is? Was out universe spawned from another?
Can you explain why you feel string theory is not real?

Our previous knowledge of physics states that traveling faster than the speed of light or even the speed of light, is impossible. So, saying you found a way to travel faster than the speed of light, you would reach the end of everything and basically only travel at the speed of expansion.
Now, though, they say it's not you who moves in space but it's space that moves around you as you travel. Making "warp speed" possible without increasing your mass to infinity. Which is the real reason light speed was impossible to reach. There just isn't enough energy in the universe to move your infinite mass at light speed.
What intrigues me is the universe expanding. Not only expanding but speeding up. But our current laws of physics state gravity as a pulling force. So, with all this mass and gravity in our universe to pull in and presumably nothing outside the edge, something has to be pulling on the universe to make it expand. That force too, has to be more massive than our own universe to over ride our gravity. Only, we can't see it, or measure it.

I have heard that at this point space is expanding faster then the speed of light. Also what was the size of the universe assuming the big bang is the cause of expansion? Was the entire universe only the size of the object in question, or was this dense object in space suspended in empty space? How much space surrounded it? If you zoom by the light emitted by the big bang will you see this "extra" space that existed during the time of the big bang?
There are things called anti-gravity that work opposite to gravity.
Posts like this always make me giggle a bit. Especially when people go past simple philosophy and start talking about string theory, advanced concepts in quantum mechanics, and other hugely advanced physics concepts when they barely have more then a background in high school physics.
People take concepts that require a doctorate in physics to have any REAL meaningful understanding of, and discuss dumb down highlights they read off of wikipedia like they are having an intellectual conversation...
People who struggle with discussions of a plane on a treadmill or a bee in a bus REALLY have no place discussing some of the most advanced and cutting edge theories in such a scientific field (myself included.)
