Time Slows Near Black Holes Explained #Space Near a black hole, gravity becomes so extreme that it warps spacetime itself, causing time to pass far more slowly than it does on Earth. This phenomenon, known as gravitational time dilation, is a real prediction of Albert Einstein’s theory of general relativity. As an object approaches a black hole’s event horizon, the time-slowing effect intensifies dramatically. In theory, someone hovering close to a black hole could experience just one hour, whil
