Okay, I have been wondering this since I first learned of Black Holes. Why is that Stephen Hawking thinks that a Black Hole could lead to another demesion? But he contradicts himself by saying that the density of the Black Hole is so strong. But if the density was so great wouldn't the density crush you under your own weight?

In an ordinary celestial body,as in a black hole the mass and gravity is concentrated at the center.
In an ordinary celestial body when you penetrate the surface some of the mass and gravity is between you and the surface,so orbital velocity would be reduced.
With a black hole,if you penetrate the surface [Where escape velocity is the speed of light] the mass and gravity is still concentrated at the center so orbital velocity would have to be greater than the speed of light.
These black holes really pose some problems when you try to make them exist.

Black holes don't have "sizes" other than the event horizon and ergosphere. The mass and size are proportional, at about 2.95 km radius per solar mass. A black hole will grow as long as the infalling mass/energy is greater than the Hawking radiation. The infalling energy can not be less than the cosmic microwave background, so any BH larger than a tenth of a millimeter will grow. As the universe cools down, larger and larger BH will begin to starve and shrink.

According to most scientists,the gravitational pull of a black hole would rip a person into atoms,so even if another dimension awaits on the other side of a black hole,no one will ever live to tell about it,at least in one piece

Oddly enough you would have a better chance with a super large black hole (think 3 Billion sun masses) than with a small one (10 sun masses). The small one would have the tidal forces rip your body apart as you approached it. Not the large one though.

I've always read that they have infinite density. That doesn't sound right to me though. Seems like using an infinity to answer a question is just a fancy way of saying "we don't know what happens in there".

Yes, it would crush you. But in theory, I have heard that your crushed remains could end up in another dimension. I am not sure I really believe it, but the math is WAY over my head so I am not qualified to deny it.
