If this speed cannot be achieved, the object will fall back down toward the solar surface.Īt the event horizon of a black hole, even something traveling at the speed of light, almost 186,411 miles (300,000 kilometers) per second would not be fast enough to escape and the only option would be to continue inward.
For an object like the sun, with a modest gravitational pull, an object only needs to travel at a speed of 384 miles (618 kilometers) per second) to escape. The speed required to escape the gravitational pull of an object, whether it's a planet or a black hole, is known as the escape velocity. In reality, black holes behave almost exactly like any other massive object in the universe. However, the black holes of science fact and science fiction are not entirely alike. They are often portrayed as vast cosmic vacuum cleaners, capable of clearing huge areas of space. They drain the life out of stars, ripping away layers of gas and shredding the component atoms. The first picture of a black hole was made using observations of the center of galaxy M87 taken by the Event Horizon Telescope (Image credit: Event Horizon Telescope Collaboration) (opens in new tab)īlack holes have a gravitational pull so intense that not even light can escape their clutches.
