Re: Is the universe infinite?
I didn't mean to get into a discussion on the physics of space travel, just presenting a simplified example to illustrate the definitions of infinite and finite. If analyzed the major flaw with the example as that as the speed increases so does the mass and if you could actually obtain light speed your mass would be infinite and would require all the energy in the known universe just to keep moving.
And no I don't think the universe is a sphere, current theory says it is either flat or saddle shaped. Both of which would make it finite. Unimaginably LARGE but still finite and expanding.
As there are galaxies moving away from us in all directions It is unlikely that we are at the edge of the universe. At the edge if space/time is being created then there would likely be fluctuations and deformations of both, can't say that I have noticed either.
So again, is there any theory for what is beyond the universe's boundaries?
