A region of space from which nothing, not even light, can escape.

A black hole is a region of space from which nothing, not even light, can escape. The name “black hole” was coined by John Wheeler in 1967 to describe these objects because it is believed that once anything passes the event horizon of a black hole, no light can be seen coming from inside its boundary.

The theory behind how and why black holes form has been under debate for decades now—but there are two main ideas: gravitational collapse and Hawking radiation. A significant aspect of both theories holds that mass causes gravity to increase with the square of distance between masses like objects or particles (see Newton’s law of universal gravitation).

The point where the gravitational field is so powerful that nothing can escape its pull.

A black hole is a region in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space.

Black holes are the remains of massive stars that have exploded as supernovas.

A black hole is a region of space-time where gravity is so strong that not even light can escape. The gravity is so strong because matter has been squeezed into a tiny space.

Black holes form when massive stars run out of nuclear fuel and collapse in on themselves. When this happens, their outer layers explode in what’s called a supernova — an explosion so powerful it can briefly outshine the rest of the star’s galaxy.

But some of these stars are too small to explode completely, and instead collapse into themselves with such force that nothing can resist gravity’s pull: not even light!

Throughout the centuries scientists have always been trying to understand our Universe and how it works.

Throughout the centuries, scientists have always been trying to understand our Universe and how it works. For a long time, they could only make assumptions about what was out there. However, over time more evidence has been gathered which has allowed us to come up with a better picture of what we can see in space.

NASA’s new telescope will help us understand more about black holes by giving us a close up look.

The James Webb Space Telescope is an infrared telescope that will be able to take pictures of black holes, other galaxies and planets.

Black holes are really dense and have super strong gravity.

You might be wondering how black holes are so dense. After all, you can’t really compress something infinitely without it being destroyed. We know that there’s a limit to how much matter and energy can be packed into one space. This limit is known as the Planck density and it’s about 10^94 grams per cubic meter – that’s a lot! So how does matter get to be this dense?

Black holes are made out of mass, just like stars, planets and everything else in the universe. But unlike other objects which have finite sizes (even if they’re big), black holes have no ‘edges’. They’re called event horizons because they represent an event horizon: if you pass through one of these boundaries then you’ll never come back out again – there will always be stuff closer than this boundary pulling on you faster than light speed.*

The reason why we don’t see our own galaxy’s black hole is because its event horizon isn’t big enough yet; but once it reaches critical mass then we might start seeing weird things happening around us too! If a star gets close enough
