a black hole is your answer and it is because when a main sequenced star collects to much energy the gravity stops and forms a black hole
a black hole.
Gravity
No. A black hole is a highly compressed massive object with gravity so strong that nothing can escape once it passes a certain point.
You are referring to a black hole.
A black hole
No. All planets have gravity. Any object massive enough to be considered a planet would have strong enough gravity that you could simply escape by jumping. It is, however, possible for an object to escape the gravity of any planet if it is launched in the right way and with enough speed.
Black Holes.
The gravity is related to the mass of the object.
Black Hole
You are describing a black hole, or singularity.
A black hole.
A black hole is an object that has completely collapsed under the force of gravity, crushing atoms and subatomic particles, and having gravity so strong that not even light can escape it.
