    Hi, I'm a little new to actively studying sciences, but I've run across a snare I hope some one can help me with. In Einstein's theory the spacetime continuum seems to function as a single 2 dimensional plane. How can that be possible?

    Maybe you have seen an analogy in two dimensions? These are often used because we are not able to think in 4 dimensions. You have to find some way of visualizing the other two dimensions. (Good luck!)

    but would that mean that objects with great mass, or any objects really, create their own space forcing natural space to bend or stretch around them?

    Well, they don't "create" space but all mass (or energy) causes spacetime to curve (which then changes the way things move, which we perceive as gravity).

    So would a Black Hole be an end point of time, relatively?

    but how does it cause a curve, isnt it occupying that same space?

    How? It just does, I guess. It's the way the universe is: mass-energy warps spacetime.

    Or maybe I don't understand what you are asking ...
