Does time slow down as you approach a black hole?

As you get closer to a black hole, the flow of time slows down, compared to flow of time far from the hole. (According to Einstein’s theory, any massive body, including the Earth, produces this effect. Near a black hole, the slowing of time is extreme.

Why does time move slower around a black hole?

To a distant observer, clocks near a black hole would appear to tick more slowly than those further away from the black hole. Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it.

What happens to time at the event horizon of a black hole?

Time stops at the speed at the event horizon, because the only speed you can cross the event horizon at is the speed of light. No faster, no slower.

Why does time slow down as you approach the speed of light?

As light is spread out by the observer moving away from the source of the light time is decreased. The faster the observer moves the more light is spread out and time slows down. Time slows down as you travel faster because momentum bends the fabric of spacetime causing time to pass slower.

How much slower is time around a black hole?

Time slows down near any massive body; black holes are merely the most extreme example. GPS satellites orbiting the Earth have to correct for the fact that time passes very very slightly more slowly on the Earth’s surface than it does in geosynchronous orbit — by about one second per every 60 years.

What happens when a clock falls into a black hole?

If the person asking is standing outside the black hole looking at a clock falling towards the event horizon, then the clock appears to move slower as it approaches the black hole… and actually, it would never fall inside the black hole because time gets infinitely slow at the event horizon.

Does time exist in black holes?

Kerr spacetime is independent of time. This means that events within Kerr spacetime do not change as time progresses. In other words, time does not exist in black holes. This means black holes are basically standing still in the context of time.

How long would it take to shine a light into a black hole?

In other words, if you were to shine a light into a black hole and gauge the time that passes before that light is subsequently reflected back in your direction, it would take forever. This light would gradually slow as it moves toward the black hole until it completely stops at the hole’s event horizon.

Why is the density of a black hole infinite?

General relativity also says that the density of the black hole is infinite because its volume is formally zero – it is a singularity. For a static black hole, the singularity is a point, while for a rotating black hole, it is a ring, but still with zero volume.
