What is the role of supermassive holes in the center of galaxies?

Question

the role of supermassive holes in that reside in the center of most galaxies as far as star production is concerned?

Answer 1

Don't know for sure. Yet, my thought would be one of (or combination of) the following . . .

~ ~ A sort of clean up vacuum for cosmic activity.

~ ~ A connection / port hole of sorts from one galaxy to another.
Sort of like how many different veins of water ways meet
up and keep trickling through together that eventually all
pour in the ocean or sea.

~ ~ That the black hole is a port hole to the 'other side'.

As far as ' star production ' that you mentioned and the role of a black hole . . . maybe a star that has been 'sucked' in from the other side of that black hole (another galaxy) gets spewed out into the other side of that black hole. . . thus we might see it as a 'new' star, a newly produced star.

Just my thought.

Answer 2

The current theory goes as follows.... Galaxies began as huge gas clouds billions of years ago with no stars, just massive amounts of gas. At the center of these gas clouds, where gravity was strongest, a supermassive black hole forms, up to hundreds of millions of times the mass of our sun. These massive black holes begin feeding immediately on the surrounding gas. This process compresses and heats the gas tremendously which initiates stellar formation via collpase in other parts of the gas cloud. These stars, when they die, in turn initiate other stellar formation in the gas clouds via shock waves. The supermassive black hole soon 'eats' all the gas within a certain radius and then stops feeding. The reason it stops is the rest of the gas is out of it's gravitational reach so to speak. This leaves a dormant, but very much present supermassive black hole at the center of the galaxy, This theory is supported by three fairly recent findings, first, all galaxies observed seem to have a supermassive black hole at the center (including ours). Second, there is a very strong relation between the size of the galaxy and the mass of the supermassive black hole. I believe the supermassive black hole, the black hole is always 1/2 of 1% the total mass of the galaxy and third, there is a strong relationship between the supermassive black hole and the velocity of the stars at the edge of the galaxy which can not be explained by current models since these stars are so far from the black hole that that gravitaional forces they feel from nearby stars is much greater than that from the black hole.

One current hypothesis in astronomy, that may or may not be correct, is that the energy released by matter falling into a supermassive black hole helps regulate star formation in the host galaxy.

I have doubts about this idea. Generally, the energy of the black hole is directed out the poles of the galaxy, in highly directed jets. Hard to see how this would affect star formation in the main body of the galaxy. It's possible that the X-rays and gamma rays help ionize diffuse gas that is still falling into the galaxy, and drive it outward---but that kind of intense nuclear activity is usually short-lived compared to the evolutionary lifetime of the galaxy.

The "black hole affects star formation" hypothesis was mostly invented to explain the correlation between galaxy mass and central black hole mass. There may be other explanations for this---after all, the contributing mass for the Black Hole and the bulk of the mass of the galaxy are actually made of Dark Matter, which has little to do with star formation.

Answer 4

I don't do science, but I always thought that black holes were some kind of planets that are so big that their gravity not only pulls on other planets very hard, but even attracts light (since light has mass). It absorbs in that way everything. And the more it absorbs the stronger it gets. I always hyphotize that eventually everything will be absorbed with the black hole. Maybe even the boundaries of our galaxy.

Answer 5

Hi It is very possible that the black holes formed first and gravitationally pulled the gas need for star formation into orbit around them. Looking at it this way, galaxies may simply be the accretion disks of the massive black holes.

Answer 6

They the portal into the Worm Hole. This will help future space travelers travel almost instantly from one Galaxy to the next. All the galaxies are interconnected through these Time/Space/Dimensional openings.
Below not a great picture, but, maybe you get the picture of what I saying.

Answer 7

Super massive black holes are burdened with the task of convincing scientists that they exist!
