No. The mass, and therefore the gravitation, of black holes, are only a tiny fraction of matter in the galaxies. The greatest part of the matter in a galaxy is dark matter - matter of unknown composition at the time of this writing.

What is the super-massive structure that exists in the middle of nearly all galaxies?

A super massive black hole.


Do galaxies have black holes in the center?

Yes, many galaxies have supermassive black holes at their centers.


Do all galaxies have black holes?

Not all galaxies have black holes. While many galaxies, including our own Milky Way, have supermassive black holes at their centers, there are also galaxies that do not have black holes. The presence of a black hole in a galaxy depends on various factors such as the size and age of the galaxy.


Do all galaxies have a black hole at their center?

Not all galaxies have a black hole at their center. Some galaxies, like our own Milky Way, do have a supermassive black hole at their center, while others do not.


Do all galaxies have black holes in the center?

Not all galaxies have black holes in their centers, but many large galaxies, including our own Milky Way, are believed to have supermassive black holes at their centers.


Do the central black holes in galaxies combine when galaxies combine?

Yes they do.


Are there galaxies with no supermassive black holes?

It is currently believed that most, if not all, galaxies contain supermassive black holes at their centers. These black holes can vary in size, with some being relatively small and inactive. However, the presence of supermassive black holes in galaxies is a common feature in the universe.


Are black holes found IN the center of every galaxy?

Not all galaxies, but it is believed that the majority of galaxies have central black holes.


Did a black hole spit out a star, and if so, what are the implications of such an event on our understanding of the universe?

Yes, a black hole can eject a star in a process called a tidal disruption event. This event can provide valuable insights into the behavior of black holes and the dynamics of galaxies. It can help scientists better understand how black holes interact with their surroundings and how they influence the evolution of galaxies.


Does every galaxy contain a black hole?

No, not every galaxy contains a black hole. While many galaxies do have a supermassive black hole at their center, there are also galaxies that do not have a black hole.


Does every galaxy have a black hole at its center?

Not every galaxy has a black hole at its center. While many galaxies do have supermassive black holes at their centers, there are also galaxies that do not have black holes.


Supermassive black holes found at the centers of galaxies are related to the properties of those galaxies in the following way?

Supermassive black holes found at the centers of galaxies are related to the stellar velocity dispersion in the bulge of the galaxy. To a lesser degree, there is also a correlation with the mass of the galaxy.
