black holes are stars which collapsed under their own gravity.
actually black holes are the masters of gravity has the most gravity ever
black holes have such great gravity that nothing, not even light can escape them. That is why they were named "black holes".
No, black holes are not living organisms, but dead stars with collapsed cores and infinite gravity.
No, this is not something material like a table or a chair. Black holes are simply an area in space where gravity is infinite.
A black hole is what is left of an object that has completely collapsed under the force of gravity.
Given that tides are caused by gravity, and that black holes are a major SOURCE of gravity, it isn't clear that black holes would be affected at all by other gravitational sources. Of course, we can know nothing at all about whatever is inside the event horizon of a black hole.
Use the gravity of the black holes
it is said that there are black holes in space which we have discovered is true and how gravity realates to a black hole is well, a black hole is said to suck away other universes we have not discovered yet gravity pulls things to the ground and a black hole uses that same pull force to suck in universes
Black holes were stars that were so massive that they collapsed on itself. The gravity in black holes is infinite and more you get closer to it, more time gets slower. Black holes suck all matter that is too close. Even light can't escape Black holes.
Gravity - Lots and LOTS of gravity. Inside the "event horizon" of the black hole, we don't have a clue. We can't see in, and no information can get out.
A black hole may have an electrical charge. This is assumed to be usually insignificant, compared to its gravity.
There is a force that unites the tides, planets and black holes. Tides are generally thought of as the rise and fall of the level of the oceans due to the gravitational effects of the moon and the sun. Planets have gravity proportional to their masses, and black holes are points of massive gravity. Gravity or its effects unite the three things listed.
