Thank you very much, that's exactly what I needed. I really should have Googled it, but I didn't want to spend that much time searching through endless search results with no relevancy to my query.

I just wanted to know because it's something I don't know. I mean that how would you find the density of a point in a sphere with no other influence, using only the mass and radius of the object and depth of the point. Just pretend that it can be compressed infinitely.

Could someone please tell me how to find the density of a point in a sphere using the overall mass and radius of the sphere, due only to gravitational forces? I can't for the life of me find any actual numbers relating density and pressure. *EDIT* Oh yeah, it's all the same material, so don't...

You know, as much as I've wondered, I've never actually looked up the dictionary definition of a dimension? Go figure. Thanks. Boy, do I feel stupid. :)

I just do not understand why it is so essential for time to be a dimension. I'm by no means a specialist in this field, and I don't really know the core workings of relativity, but why is it that time must be, or at least is almost always referred to as a dimension? The only way I seem to be...
