## Is a Gravity Well a black hole?

What is a black hole? A black hole is a “gravity well” that is so strong that NOTHING escapes from it, not even light.

What is a gravitational well?

A gravity well is the pull of gravity that a large body in space exerts. The larger the body (the more mass) the more of a gravity well it has. The Sun has a large (or deep) gravity well. Asteroids and small moons have much shallower gravity wells.

Can gravitational waves escape a black hole?

Waves on such trajectories cannot escape from the black hole, so the basic answer is no, gravitational waves cannot “pass through a black hole”.

### Are there gravity wells on Earth?

The more massive the object, the deeper the well. For example, the Earth is much more massive than the Moon and so has a deeper gravity well or a stronger gravitational field. The deeper the gravity well, the more energy is required to escape from it.

What is beyond a black hole?

At the center of a black hole the gravity is so strong that, according to general relativity, space-time becomes so extremely curved that ultimately the curvature becomes infinite. This results in space-time having a jagged edge, beyond which physics no longer exists — the singularity.

How far is the gravitational pull of a black hole?

(That means it has a lot of mass, which means it has a really strong gravitational pull – much stronger than even our Sun’s gravitational pull.) If Earth gets within about 800,000 kilometres (3.7 light seconds) of this black hole it will get pulled apart.

#### What shape is a gravity well?

For the benefit of those readers not familiar with the subject, the gravity-well is a surface of revolution formed by rotating a suitably shaped curve around a central vertical axis, sweeping out an axisymmetric surface resembling the bell mouth of a horn.

What can escape a black hole?

Black holes are the blackest things in the universe. Because of their enormous, space-bending gravity, everything that falls into them is instantly ripped apart and lost. Scientists have never seen a black hole, because nothing, not even light, can escape them.

How far is earths gravity well?

The cut out also shows objects like the International Space Station, the space shuttle, GPS satellites and geo-stationary satellites at their respective positions within Earth’s gravity well. The depth of Earth’s gravity well is listed correctly at 6 379 km (note the difference from the non-cutout number).

## How far does Earth’s gravity well extend?

The Earth’s gravitational field extends well into space it does not stop. However, it does weaken as one gets further from the center of the Earth. The Shuttle orbits about 125 mi above the surface, roughly the distance between Jackson and Nashville!
