The 'center of gravity' of any object or volume of space is a point in space ... a place,
with a very clear definition. It's the place where the sums of the first moments of every
speck of mass in every direction are all equal. If the object or the volume of space has
any mass in it, then the center of gravity can be located very precisely and very easily
by applying the definition.
actually black holes are the masters of gravity has the most gravity ever
black holes are stars which collapsed under their own gravity.
The strength of a black hole's gravity depends on the black hole's mass and how far your reference point is from the center of mass.
Black holes are the cause of gravity... Black holes are created when a supernova condenses, creating a black hole. It condenses because gravity has won the battle between the star's core. So basically, gravity fuels a Black hole.
Gravity. However, it isn't yet entirely clear how galactic black holes could grow to their current size in a relatively short time.
black holes have such great gravity that nothing, not even light can escape them. That is why they were named "black holes".
Black holes are created when in a Supernova-explosion or after a collision between two neutronstars (which are mini black holes). The star collapses and the gravity becomes stronger and stronger, dragging everything towards the center. In the end, the gravity becomes so strong that not even light can escape.
Yes, many galaxies have supermassive black holes at their centers.
Earth is a planet. Center's of galaxies sometimes contain black holes. Planets can't be black holes.
No, black holes are not living organisms, but dead stars with collapsed cores and infinite gravity.
Black holes are round due to the intense gravitational forces pulling matter towards the center. This gravity acts equally in all directions, resulting in a spherical shape. Any irregularities in shape would be quickly smoothed out by the immense gravitational forces at play.
Black holes are not present in the center of every galaxy, but many galaxies, including our own Milky Way, have a supermassive black hole at their center. These black holes have a gravitational pull so strong that not even light can escape from them.
