Everything we understand about the universe is currently built on two pillars; Albert Einstein’s theory of general relativity and quantum mechanics. Einstein’s theory of general relativity deals with the large, macro-level of the universe, and quantum mechanics deals with the micro-level. Currently, these two pillars work very well on their own but don’t often work very well together, and their unification is generally accepted as one of science and physics’ great contemporary issues. The accomplishment of which in the form of some unifying equation would be deemed, potentially, The Theory of Everything. Both of these pillars, however, appear to find themselves in a rather strange situation inside black holes, where neither seems to work. Based on Albert Einstein's theory of general relativity, black holes create a singularity, and that’s how we are able to form the conclusion of it being there. However, according to physics, that’s impossible. You can’t have an infinite density or infinite gravitational force or infinite anything in physics. Infinity, to our knowledge, cannot be real in a physical, measurable sense, and when it appears in equations, it’s essentially a sign of an error or impossibility. And thus, Einstein’s theory breaks down. At the minute scale of the singularity, typically quantum field theory would step in. But quantum field theory can’t work here either because it can’t yet explain gravity, and the functions of black holes and the singularity are primarily based on gravity. And so, it seems that somewhere between the edge and core of black holes is either the separate collapse of both theories, destroying much of our understanding of everything, or the unification of both theories, creating a supposed ultimate theory of everything. In this sense, the primary answer needed for the complete understanding of the universe happens to potentially be contained and hidden in a place that nothing can seem to ever enter and come out of. A potential final frontier of human knowledge guarded by a mammoth-sized galactic beast. Perhaps this beast is undefeatable. Or perhaps we simply lack the mathematical weaponry to properly fight it. In the past, for many of the greatest and most confusing paradoxes in history, even greater minds and greater efforts have come along, confronted, and beat them, dissolving such paradoxes away into the falsidical realm forever. And perhaps here, inside black holes, we will do the same again. Either that or perhaps we will be dissolved by the paradox first.
