I especially like the idea of infinite dimensions, because it is the only other sensible 'number' of dimensions apart from zero for the initial state of the universe before the Big Bang. I personally feel that the dimensions themselves must have been created by the Big Bang, i.e. they weren't a...

Another way to explain why there are 3 dimensions (+time) is that spacetime was created by the Big Bang. Since the Big Bang started from a singularity, that singularity could have been actually an initial 0-dimensional universe. That might seem far-fetched, but it is the only way to account for...

So, do we assume that an the 3 dimensional space (+ 1 dimension for time) needs to be in-place before the Big Bang for the laws of physics to work - placed there by an Act of God? Or did the Big Bang itself create 3 dimensions + 1 time from (zero dimensional) nothing? I do the physical laws...

Thanks for the replies. Another question: Any idea why is the universe not zero-dimensional? Zero is just a more fundamental number than 3. I'm wondering if there could be a cause that's different than the anthropic principle.

I think because the number 3 is still pretty low it isn't so suspicious to people, but imagine we lived in some universe with, say, 186 dimensions (that miraculously supported intelligent life, so there's someone to ask the question - I know about the anthropic principle). Wouldn't we have asked...

I found a good article on the subject at [PLAIN]"www.physics.umd.edu/grt/taj/776b/chappell.pdf"[/URL]

Lol, just saw in the Similar Threads section someone has asked about "Stuffing a black hole full of electrons?" (link is https://www.physicsforums.com/showthread.php?t=392989) So I'm not the first one to think about it. In his thread they reach the conclusion that when the black hole is charged...

Hey, thanks for the answer. So is a naked singularity going to happen, and if not, what mechanism will prevent the negative charge from accumulating? You seem to imply that something will happen that will prevent us from seeing the naked singularity.

This may be a stupid question but what would happen to a black hole if you point a stream of electrons at it and keep it up indefinitely, until it's made almost entirely of electrons repulsing each other, with no protons to balance the charge? Or is the principle of charge conservation violated...
