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.
Spaghettification is a term that describes the extreme tidal forces experienced by objects falling into a black hole. These forces can stretch and elongate objects, like spaghetti noodles, as they get closer to the black hole due to the intense gravitational pull. This phenomenon occurs because the gravitational field of the black hole is so strong that it creates a large difference in gravitational force on different parts of an object.
A black hole forms only when the star is large enough that the gravitational pressure exceeds the quantum degeneracy pressure.
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.
The most massive stars will die as black holes.
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.
Black holes are the result of the gravitational collapse of a large star.

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.

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.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
the objects with the greatest mass and the ones that are closest to other objects

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.
Black holes. They can be so large that they can suck up universes at a time
Most black holes were once the cores of very large stars that collapsed.
Astronomical bodies like planets, stars, galaxies, and black holes contain a lot of mass and are considered large in size in the field of science. These objects have a significant gravitational pull due to their mass and play crucial roles in shaping the universe.
