Black Holes in Particle Physics

The Standard Model of Elementary Particles emerged empirically as an extremely efficient way to describe all particles and forces that have been detected experimentally thus far. However, in these experiments, the gravitational force was far too weak to be taken into account. In our attempts to include gravity, we encounter the difficulty that black holes might form. Their very nature causes unforeseen difficulties when we try to formulate a theory consistent with quantum mechanics. Is there information loss? Is quantum mechanics still valid? Will general relativity be an exact symmetry for very energetic particles?
