The centre of a galaxy is there a black hole like in case of small galaxies?

Question

what is present in the centre of a galaxy of very big size?

Answer 1

Hi. Try this link for a photo of the area near our own black hole. : http://chandra.harvard.edu/photo/2003/0203long/

Answer 2

they say there is one at the center of the Milky Way ( our galaxy ) but we can't see that far ( density is the problem - lots of gas clouds and stars in the way )

all we know from observation is that stars are closer together at all galactic centers ( except perhaps cluster or globular galaxy's ) all else is speculation and theory - it does stand to reason that with more density you would have more stars colliding and merging , eventually the result would be a star that is so massive that it implodes and forms a black hole - but there may be forces that prevent this that we haven't discovered yet after all BLACK HOLES ARE THEORY we haven't observed one ( no matter what Hollywood and Science Fiction implies !!! )

Answer 3

while black holes are "theory", there is very strong evidence for their existence. The real questions are exactly how they behave.

The behaviour of the stars at the centre of the galaxy suggest a black hole.

Generally, a very large Black Hole.

Answer 5

In our galaxy it is believe that there is a superblack hole in the center of it!
