What is a black hole the result of?
Gravity density. Whenever a sufficient mass is squeezed into a small enough volume ... then a black hole occures. "Normally" this only ocures when a massive star runs out of (hydrogen) fuel and collapses in on itself.
If gravity waves travel at the speed of light and black holes' escape velocity is much greater than the speed of light then how can gravity waves escape a black hole?
Gravity is not a 'wave', it is a field of curvature of space-time caused by objects with mass. A black hole contains the mass of a star, compressed to the space of a single atom (a singularity), the compression of so much mass into such a small space, is why the black hole has such a powerful gravitational pull.
Does regular planets have weak gravity?
Generally speaking, the bigger or more massive a planet it, the more gravity it has, since gravity and mass are related. the small planets such as Mars and Mercury have a weaker gravity, while the larger planets have a strong gravitational field.
Can you explain the concept of a black hole in a way so that kids can understand?
The basic idea is that masses attract one another through a force called "gravity", and that such a force depends on the amount of mass, and the distance. It is possible to have such a large mass in such a small space that even a ray of light can't escape from such a region, due to the gravitational attraction.
What does gravity have to do with black holes?
Black holes are only theories. They halve not been proven, although it is likely they exist. The theory goes, a large (super massive) mass has so much mass it implodes creating a rift in space time contium. This implosion is due to the extreeme mas of the object, it would be unimajanalbly massive. So the force of gravity created by its own mass makes the mass smaller, too small, until it implodes. Have a look into Special relitivity.
What is so small and massive that it's gravity does not let light escape?
A black hole because it can be small and massive and not even light can escape it.
What is so small and massive that it's gravity does not even let light escape?
A black hole because it can be small and massive and not even light can escape it.
What is so small and massive that the gravity does not even let light escape?
Black holes - and not all are small.
The remains of a massive star pulled into a small volume by gravity?
A black hole is formed when the remains of a massive star collapse under their own gravity, creating a region of spacetime where gravity is so strong that not even light can escape. The mass is concentrated into a small volume called the singularity at the center of the black hole, surrounded by an event horizon beyond which nothing can escape.
Why are black holes black and what causes them to have such a strong gravitational pull that not even light can escape?
Black holes are black because their gravitational pull is so strong that not even light can escape from them. This strong gravitational pull is caused by the massive amount of matter packed into a small space, creating a dense and compact object with intense gravity.
What is the remains of a massive star pulled into a small volume by gravity?
A black hole
What are black holes made of and how do they form in the universe?
Black holes are made of extremely dense matter that has been squeezed into a small space. They form when a massive star collapses under its own gravity at the end of its life cycle. This collapse creates a gravitational pull so strong that not even light can escape, creating a region of spacetime from which nothing can escape, known as a black hole.

Why doesnt the gas on a gas gaiant escape into space as it has on mercury?
it's small size and low gravity
What kind of gas is most affected by thermal escape?
Hydrogen is the gas most affected by thermal escape in planetary atmospheres. Its low molecular weight makes it more likely to escape a planet's gravitational pull and be lost to space over time. This process is most pronounced for small, low-gravity planets.
Do large planets such as Jupiter and Saturn have gravity?
Anything with mass has gravity. Anything massive enough to be considered a planet has noticeable gravity, whether it is a giant planet like Jupiter or a small planet like Mercury.
