The Center of a Black Hole: Infinitely Massive Singularity or Portal into another Universe?

Black holes are one of the most naggingly peculiar objects in the universe. Beyond the event horizon of a black hole, our equations are turned upside down; they also get turned inside out when we attempt to fathom the singularity at its center when using the equations given to us by Einstein. To make life simpler, what if we removed the singularity all together? There is some math for that.

Coming full circle, it suggests that black holes do not hold singularities in their interior, but portals to another universe.
