A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The boundary of no return is called the Event Horizon.
Our simulation uses the Schwarzschild metric, which describes the gravitational field outside a spherical, non-rotating mass. It is the simplest type of black hole solution in Einstein’s theory of General Relativity.
Massive objects curve spacetime. Light follows these curves, meaning “straight lines” (geodesics) in curved spacetime appear bent to a distant observer. This causes:
Matter falling into a black hole forms a disk. Friction heats this matter to millions of degrees, causing it to glow.
