TIME NEAR A BLACK HOLE MOVES DIFFERENTLY According to Einstein’s theory of relativity, time slows down in extremely strong gravitational fields. Near a black hole, especially one like those observed by NASA, time dilation becomes extreme. An hour close to the event horizon could correspond to years — or even thousands of years — for distant observers. Important Details: • Gravitational time dilation effect • Predicted by General Relativity • Stronger gravity = slower time • Extreme near event ho
