The source of its gravity is its mass. Black holes also have the property of being very dense. Black holes by definition are objects where the escape velocity is equal to or greater than the speed of light.
No. While the gravity of Jupiter is much stronger than Earth's it is nowhere near as strong as that of a black hole.
Black hole is a location in space that possesses so much gravity, nothing can escape from its pull. Yes, Super massive black hole is the largest black hole.
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 relates to physics, because it "bends" the laws of physics. Noone really knows what a black hole does. It bends the law of gravitation (a black hole has way too much gravity).
A giant supermassive black hole is just remains of a once great star, and it collapsed into on itself, pressurizing so much gravity that it makes a hole in time and space in this universe, sucking in anything, so basically it is just a hole of gravity.
None, unless it was to draw some in via gravity.
This is a common cause of confusion. In a way, if no mass got lost in the creation of a black hole, then it will have exactly the same gravity than before. For example, if our Sun converted to a black hole (not that it is planning to do so...), our Earth would continue orbiting this black hole, in the same orbit as before. What makes a black hole different is that the mass is very concentrated; so, it is possible to get much closer to the black hole - and remember that gravity gets stronger at shorter distances.
Stars want to expand when they are active, but their high gravity keeps them the right size. When stars are too old they stop expanding, and its gravity makes it very small. If an object has too much mass for its size, it is a black hole.
A black hole is an object in space with such intense gravity that not even light can escape from it. When an object crosses the event horizon, the point of no return around a black hole, it gets pulled in by the strong gravitational forces, making it impossible for anything, including light, to escape.
A black hole has so much mass that light can't escape from it once it passes the event horizon. It can still escape if it hasn't passed the evnt horizon.
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.
The value of g is infinity in the case of intense gravity means where there will be more mass there will be more gravity and the black hole is the place where there is too much mass and too much gravity so the answer of your question is that in the singularities or in the black holes the value of g becomes infinity.
