If light cannot escape a black hole, why does its gravity still reach us?
Black holes are defined by an event horizon from which nothing, not even light, can escape. Yet, these objects exert a powerful gravitational pull on the surrounding universe. This video investigates the mechanism behind this apparent contradiction, explaining how gravity communicates from within the singularity.
The core of a black hole is a singularity, a point where all its mass is concentrated. Surrounding this singularity is the event horizon, a boundary that light cannot cross to return to the outside world. Because gravity travels at the speed of light, it seems paradoxical that the gravitational influence of a black hole is felt beyond this threshold.
The video explores the physics of how a black hole maintains its gravitational connection to the rest of the universe despite the light-speed limit imposed on information and matter.
