The strength of the gravitational field depends on the mass, and on the distance. Since in black holes, the mass is concentrated in a very small region of space, it is possible to get very close, and still have all the mass on one side.Please note that at a given distance, say 100 million kilometers, a black hole with a certain mass has exactly the same gravitational field as a star of the same mass, at the same distance.

How come all stars don't form into black holes?
A black hole forms only when the star is large enough that the gravitational pressure exceeds the quantum degeneracy pressure.
Does the gravity affect the magnetic force lines by space distortion?
Magnetic lines of force follow space. If space is distorted by the presence of a large gravitational field, the magnetic lines will be distorted as well. Other than near black holes, this effect is negligible.
What are the uses of black holes?
Since most, if not all, galaxies are believed to have a central supermassive black hole, it could be said that black holes provide the gravitational underpinnings for the large scale structures of matter in the universe. Because they power quasars, the brightest and most distant objects known, they also give information to understand the scale and age of the visible universe. They continue to be of great scientific interest for several other reasons, one of which is that they illustrate the incompleteness of our physical models - since we don't have a system which adequately describes conditions and laws at the black hole singularity, where our current laws of physics appear to break down.
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
What thing in this universe can bend the light?
According to Einestein's theory of general relativity, any massive body that causes an appreciable distortion in its surrounding space-time can bend light (e.g. large stars, black holes, etc.). Light that enters the event horizon of black holes are bent so much that it can never leave the black hole.
How are black holes related to stars?
Black holes are the result of the gravitational collapse of a large star.
How come all stars don't form into black holes?
A black hole forms only when the star is large enough that the gravitational pressure exceeds the quantum degeneracy pressure.
Are black holes the corruption of quantum foam?
Black holes are basically large amounts of mass in a small space - when matter is concentrated to such an extent that the gravitational force becomes so strong that a ray of light can't escape this space.
Are black holes similar to vortexes?
No. A vortex is an area of a rotating liquid or gas. A black hole is an extremely powerful gravitational field created by a massive object that has collapsed to a single point. If a large amount of matter falls into a rotating black hole it can form a sort of vortex called an accretion disk.
What were black holes before they turned into black holes?
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
Does the gravity affect the magnetic force lines by space distortion?
Magnetic lines of force follow space. If space is distorted by the presence of a large gravitational field, the magnetic lines will be distorted as well. Other than near black holes, this effect is negligible.
Is Earth's gravitational field the same as its electromagnetic field?
No. Earth's gravitational field is due to the large mass within it; the electromagnetic field is due to the movement of the metals in its core. There are also the standard differences between a gravitational and an EM field.
What waves whose source includes black holes?
GRAVITATIONAL WAVES are the result of large accelerations of masses. The three cases of observations of gravitational waves that have been announced so far, all of them by LIGO, are all the result of collisions of black holes; however, other events would also produce gravitational waves, and might eventually be detected, such as collisions between neutron stars, a star collapsing into a black hole, etc.

What is bigger black holes or asteroids?
Black holes. They can be so large that they can suck up universes at a time
What did black holes used to be?
Most black holes were once the cores of very large stars that collapsed.
What do very large mass star become at the end of their life cycle?
The most massive stars will die as black holes.
