I've heard theories of gravity traveling along a 5th dimension. What is this 5th dimension? Could this hidden dimension be the size scale moving infinitely up and down making it inaccessible due to the electromagnetic force being so much stronger than gravity? Could a black hole be something which allows matter to travel along this dimension freely, due to it's gravitational forces being stronger than the electromagnetic force?

I haven't heard of it traveling along a 5th dimesion per se, but I have heard of gravity originating in a multi-dimensional multiverse containing (among many others) our 3 dimensional Universe as an explanation of why gravity seems so much weaker than the other forces.

This is well explained in Brian Greene's book "The Fabric of the Cosmos: Space. Time. And the Texture of Reality"

Gravity is many orders of magnitude weaker than EM!

It's gravity is just normal gravity. It doesn't become proportionately "stronger than the electromagnetic force", there's just more of it (or more accurately, the same amount of gravity in a smaller space). If there were the same amount of EM, it would blow the Black Hole apart against its own gravity.

I said forces indicating a cumulative effort on gravity's part.

What exactly does that mean? Gravity has the same properties whether it's high or low.

I think he means there is enough of it that it's "stronger" than EM, not that gravity itself is actually stronger than EM itself.

Well, that's true of every body that produces heat. Earth, for example. We hold our own mass against our internal EM emissions quite well.
