How does General Relativity relate to black holes?

Black holes are regions of spacetime where gravity’s pull is so strong that nothing, not even light, can escape from being dragged in and “eaten.” Einstein’s theory of general relativity predicted the existence of black holes and that, no matter what such an object “eats,” black holes are characterized only by their …

How does black hole bends the theory of relativity?

The X-rays that reflected on the gas behind the black hole were bent around the black hole, and these smaller flashes arrived at the telescopes with a delay. These observations match Einstein’s predictions of how gravity bends light around black holes, as described in his theory of General Relativity.

Does time slow down near massive objects?

That’s because of time-dilation effects. First, time appears to move slower near massive objects because the object’s gravitational force bends space-time. That’s why time passes slower for objects closer to the center of the Earth where the gravity is stronger.

How does time slow down near a black hole?

An object approaching the event horizon would appear to be slowing down as it approaches the black hole instead of speeding up as we would expect. This is because of time dilation, which slows the passing of time for an object moving close to the speed of light with respect to an outside observer.

How do black holes affect space-time?

According to Einstein’s General Theory of Relativity, any massive object actually distorts the space-time around it, including our Sun, Earth, or even us. A black hole is an extreme case in the sense that at its singularity the curvature of space-time becomes infinite, preventing even light to escape.

How can time slow down in space?

Time dilation goes back to Einstein’s theory of special relativity, which teaches us that motion through space actually creates alterations in the flow of time. The clock in motion will tick more slowly than the clocks we’re watching on Earth.

How do black holes slow down time?

Why does time get slower near a black hole?

The simplified answer is: Due to gravitational time dilation. A black hole provides a way to go faster into the future of a region of higher gravitational potential away from the black hole. But the body near the black hole needs to withstand the high gravity.
