can anyone go into any detailed theories about what exactly it is?

Erm, a theory on a super-sized galaxy (if that's what you want to call it?) that is sucking the Milky Way, etc. in it's direction???

All I know/have understood, is that the Great Attractor is bigger than any galaxy that is known today. There is something to do with it's level of gravity(?) that is pulling the Milky Way and other nearby galaxies in it's direction. There was no understanding of it's existence as it goes way beyond our galaxy plane.

I personally couldn't give a theory, so I'd also love to read anyone elses.

Thats all I've ever heard either, it's very, very large, and very, very dense.

Hello from what I have read the great attractor is far larger than a Galaxy in fact it is larger than a galaxy cluster. Because it is blocked from view by the Galctic plane we have never seen it however there are xray images of it. It is a massive super cluster within Abell 3627 and it is indeed pulling the Milky Way and Androemeda toward it. I found an image taken by the ROSAT sattelite.
