A galaxy doesn't just suddenly collapse. Over a long, long time - much longer than the current age of the Universe - it is expected that galaxies will gradually "evaporate", in the sense that momentum is transferred to some stars, enough to let them escape from their galaxy. The momentum of other stars decreases, and they get closer to the central black hole - many of them will be absorbed by this black hole eventually.
The theory of a black hole and galaxies is that a black hole created a galaxy or was formed by a galaxy, if that makes sense.Eventually, our solar system will get sucked in. But this will happen in about over a billion years!add. For such a size of black hole, the timescale would be in the billions of years. But before which our Sun would have overwhelmed our Earth in its Red Giant phase.
no it does not depend on the black hole in the middle of the galaxy
no the galaxy is way to big for a black hole to do much in fact we now know that there is a supermassive black hole in the center of our galaxy right now.
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.
The Milky Way (our galaxy) is believed to have one in the center. Every or almost every galaxy has a black hole in the middle of it.
No. No black hole is big enough to do that.
No, the sun does not orbit a black hole in the center of our galaxy. The sun orbits around the center of the Milky Way galaxy, where there is a supermassive black hole called Sagittarius A.
It seems that just about EVERY galaxy has a huge ("supermassive") black hole in its center.
every galaxy got a black hole in the center even our galaxy, the milky way.
A blazar is an elliptical galaxy with a supermassive black hole at the center.
Yes, the M65 galaxy is thought to have a supermassive black hole at its center, like many other large galaxies. This black hole likely plays a crucial role in shaping the galaxy's properties and evolution.
It is believed that all galaxies have a black hole at their centers.
