Question

if most galaxies have a black holes a the centre of them, will a galaxy end by getting wiped out into it's own black hole?

Answer 1

All the previous answers are true, But they all miss one important thing in some rare cases even maybe to our own Galaxy and the Andromeda Galaxy, these two Galaxy's may one-day collide and if this happens one of two things could happen.

1. The gravitational pull of the two Galaxy's could make then grow into one massive elliptical galaxy drawing in all the other matter and stars around it.

2. Or the two galaxy's could become slightly gravitationally linked and the two black-holes at the centre of the two galaxy's could start circling each other and start throwing jets of gamma-rays out into space creating whats called a lens flare, a good example of this is the hourglass nebula which is a result of a similar fate.

I hope that this answers your question

Answer 2

No.
While a black hole is a very *strong* gravity source, it's just a gravity source like any other. Only objects that are close to the event horizon, and get their linear motion slowed by other means, will be pulled in. Otherwise, no matter how close or far away they are, they will continue to orbit the black hole, never "falling" in. Our planet orbits the sun, keeping the same orbit year after year after year, never "falling" into the sun -- the same is true of an object orbiting a black hole. When an object is close enough to the black hole, tidal forces can slow the object's linear motion enough to drag it in (slowly) -- but otherwise the orbit will just continue forever.

Remember, any orbit is a combination of linear motion (the object moving tangent to the path of its orbit, always keeping its momentum according to Newton's second law of motion), and motion towards the gravity source being orbited due to the pull of gravity. As the object moves linearly, gravity pulls it in, resulting in a curve (an ellipse). Any orbit is a balancing act between those two forces. Absent any force to change the linear motion, the two forces will balance in their elliptical shape forever, without the orbiting object ever "falling" into the gravity source. Just because a black hole is a BIG gravity source doesn't change the equation any. It's still a stable system absent other forces.

Answer 3

The stars are in more or less stable orbits about the central black hole. There are a number of hypervelocity stars which have passed too close to the central BH and are now being flung out of the galaxy.
Simulations of galxies show that stars oscilate within bands in their orbit but unless some other factor is at work they don't normally get sucked in.

Answer 4

sure, there's a black hollow on the midsection of our galaxy. Our galaxy isn't increasing. it relatively is shifting removed from different Galaxies. many people get at a loss for words via the incontrovertible fact that the Universe is increasing and then assume that the galaxy does too. there's a factor on the sting of a black hollow referred to as "the form horizon", a factor of no return for stars. Many stars orbit the black hollow, yet don't get close sufficient to be drawn into it. all of them do no longer stay in a concise orbit, in spite of the incontrovertible fact that. in the event that they veer too a lot in direction of the black hollow they attain that factor of no return. Our galaxy has nebulae which create stars. So, stars are lost and others are born.

Answer 5

According to the latest findings from Hubble space telescope ,every galaxy contains a super massive black hole at the center of it..this means that the birth of the galaxies is infact the resultant of these super massive black holes. the stars in the galaxy are formed because of these super massive black holes..

Answer 6

I'm not one of the four digit I.Q. guys who dream up theories. I'm just a guy who thinks about a lot of things. For years I have considered what you are discussing and I like the theory.

It seems to me that eventually all the stars will be drawn over the event horizon and into the black hole. Then I see the black holes colliding and combining into one singularity. That one singularity may again explode in yet another "Big Bang" in this series' of oscillating universes.

I.E. it makes sense to me...

Answer 7

The universe is not that stupid.
If a black hole could exist it would,eventually accrete all the matter in the universe and sit doing nothing,for eternity.

Answer 8

not if the pull is too great.
