We believe that the universe is unbounded: this is not the same as infinite: the 2-D surface of a sphere, wrapped around a 3rd dimension, has a finite size, but has no end. If you start off in a given direction on the surface of a sphere, you could return to your start point without having to turn around -- you simply go all the way around. But wouldn't that mean the universe has an escape velocity like the earth?

I don't know very much about physics etc, but would it be possible to build an actual magnetic accelerator? How much power would it take to launch an 8lbs shot put ball a mile or two?
As far as i can figure out you would need some very powerful electro magnets, some kind of way to cool them, some large something-erathers to amp up power to then dump into the magnets and some way to ensure you dont blow urself up.
How would one seriously build one? Any ideas?
It is extremely plausible. The Coilgun is already a primitive example of a future MAC.
