Hello,
I understand that String Theory requires 10-11 dimensions, depending on the specific author of the theory. M-theory requires 11. My question is, why do we need the extra dimensions? All I've read is that they are needed to make the equations work, but no one goes into what they mean by that.
I think it is because we need extra "space" for the strings to travel through when they are not affecting our dimensions. So they could be in these spherical or curled up dimensions that co-exist within or outside our 4-dimensional space.
Can anyone elaborate on this at all? I'm confused but highly interested by string theory.
Thanks,
