BigBang

Thanks for the informative replies! I never thought of using the concept of limits, but that actually makes the whole concept of a singularity easier to understand for me.

I am having trouble understanding why, according to the Big Bang Theory, density at the point of singularity is infinite. Here is my train of thought. Volume at point of singularity = 0 Density = Mass / Volume Density at point of singularity = Mass / 0 Density is undefined. I don't understand why density is infinite at the point of singularity if the simple calculation above yields an answer that is undefined. Are my calculations incorrect?
