Nothing escapes the black hole because its gravity is so strong. Gravity is the force that pulls one thing to another. It keeps us on Earth. When you jump up, earth’s gravity pulls you back down. Earth’s gravity also causes the moon to revolve around the earth.

The strength and power of black holes
The more matter (matter) is packed into a star, planet, moon or other object, the stronger its gravity. Gravity causes an object with more matter to attract an object with less matter. The Sun has much more matter than the Earth. The sun’s gravity pulls on the Earth and makes it revolve around the Sun.

Matter is very densely packed in some things and weakly in others. The material that makes up the iron ball is packed much more densely than the material of the feather bag.
The black hole is denser than you might imagine. It can contain a million times more matter than our Sun. The gravity from so many things packed in such a small area is amazing.

Where do black holes come from?
Astronomers and physicists believe that black holes arise from dying stars. The dying star burns out and ceases to shine. All the matter of which the star is composed begins to fall on itself. The star is getting denser and denser. If a star is large enough and has enough matter, it can turn into a black hole.

Study of the phenomenon
Nobody has really seen a black hole. You cannot see black holes because they do not emit any light. Physicists have used mathematics to predict the existence of black holes.
Astronomers are looking for signs of black holes. They study powerful rays emanating from stars in deep space. Stars seem to revolve around black holes. Astronomers believe that black holes suck in gas from stars, and this causes the stars to emit X-rays.

Galaxies are huge groups of stars. Astronomers believe that most galaxies have huge black holes at their centers. The Hubble Space Telescope has captured images of a disk of hot gases at the center of our own galaxy, the Milky Way. Astronomers believe that this disk is orbiting a huge black hole right in the center of our galaxy.
