Final answer:
Black holes can be modeled using computer simulations on supercomputers and through theoretical models and mathematical equations. Observations made using advanced telescopes have also provided evidence for the existence of black holes.
Step-by-step explanation:
Black holes are extremely complex objects to model, and computer simulations are currently the most widely used method to study them. These simulations require supercomputers capable of performing numerous calculations per second to accurately describe the behavior of black holes.
Another method of modeling black holes is through theoretical models and mathematical equations developed by physicists. For example, Roger Penrose has developed mathematical models related to black holes. Additionally, observations made with advanced telescopes, such as the Hubble Space Telescope, have provided evidence for the existence of black holes.
