Investigating the Plausibility and Implications of Micro Black Hole Creation in High-Energy Particle Collision Experiments

Theoretical predictions suggest that micro black holes could potentially be created in high-energy particle collisions, raising public concern for decades. Our researched aims to investigate this possibility. To start, we derived an approximation for Hawking radiation, indicating that a micro black hole would evaporate almost instantaneously, even when considering special relativistic effects. In the event that the black hole does not evaporate, we found that the black hole would move around inside of the Earth without significant absorption of matter. Our derived equation for particle absorption over time shows that on average it would take much longer than the current age of the universe to absorb a single particle. We then modelled the motion this black hole would take based on initial conditions, such as the location it was created and the initial velocity. Assuming constant density of the Earth and requiring that the black hole does not leave the surface, we found an analytical solution for this motion indicating that it is an elliptical orbit with a constant period. Further numerical simulations allowed for the inclusion of realistic density distributions of the Earth along with the possibility for the orbit to exit the surface. In both cases, this causes a precession of the orbit to occur over time. Our findings suggest that the creation of micro black holes is highly unlikely and poses no significant threat to the Earth. The goal of this presentation is to discuss the processes and results of our calculations.
