Q&A: Black Holes

Q:
Should it be concluded that black holes reach unimaginable limits of expansion?

A:

Illustration of the Growth of the Biggest Black Holes
Black holes in the Universe do not grow without limit. The vastness of space and the relative weakness of gravity mean that even very massive black holes, like the one in the center of our Milky Way galaxy, cannot pull in many of the objects surrounding them.

The Chandra web pages contain a lot of information on black holes - we suggest the black hole photo album:
