about 3 x 10^6 Solar masses contained within 20 million Km or thats how it stood when i wrote a paper on it for the second year at uni LOL.
From everything i read the most logical thing i thought of was that if you have so much matter knocking around and these galaxies formed out of fluctuations in matter densities. then why couldnt these black holes form during the early stages of the universe, the matter inturn clumps around these holes and form galaxies?
