apparently most galaxies have a black hole at the centre of them, stars wont get sucked into them unless they stray too close to the horizon point (which is where everything gets sucked in)
only stars at the very centre of the galaxy have a chance of this. most stars will just keep orbiting the black hole in the much the same way planets orbit our sun.

The existence of blackhole is just a theory.
It was theorized that a giant blackhole is in the centre of a galaxy, due its enormous gravitational force. Since they need to to figure it out on how a galaxy didn't fall apart and stay together.

There is no black hole at the center of any galaxy.
It is strictly a theory.
Some astronomers have used the movement of stars to verify it.
A star is a very sturdy entity in it's environment,but it is very fragile beast if you try to move it around.
The claim says that the stars are in highly elliptical orbits,they would be destroyed when they passed near the black hole then started to pull away.
Consider the comet that crashed into Jupiter,it made one pass and was fractured,hitting Jupiter as many pieces on the next orbit.
A black hole is a very logical,theoretical entity but it can't stand up to a very objective analysis.
They don't exist!

Spiral galaxies (including ours) do look to have a black hollow at or very close to the centre, as evidenced through stellar orbits and gentle curves. considering elliptical galaxies are considered formed through a collision of spirals (our galaxy and Andromeda are due for basically the type of collision in some billion years), there would must be one there to boot. honestly, elliptical galaxies look to have some distance more beneficial mass than they ought to (again judging through stellar orbits), so probably the black holes in the spirals merge into one at the same time as the elliptical galaxy is formed.

Yes - astronomers believe that there are black holes at the centre of every single galaxy, including our very own Milky Way.

Yes there is. That's what makes our galaxy and others look like a galaxy. Due to the Supermassive Black Holes gravity. If you moved the Supermassive Black Hole to the outer edge of our galaxy all the other stars would center themselves around it again. Just so you know it's not a black hole in the middle it's a Supermassive Black Hole.

There's good evidence to say that there's a black hole in the centre of our galaxy. Stars are seen to be orbiting something massive but very compact and there are X-ray emissions that match what would be expected if there's one there.

yes, there is a supermassive blackhole in the center of the milky way

yes, in the center of our galaxy there is a big blackhole
and as time goes, million years later or thousand years later the earth and our entire planetary system around us will end up in there... but don't worry it's still a long time before we got sucked up....

yes the big hole is in the centre of our galassy.... Sagittarius
