I<\/span>t\u2019s been obvious for a while now that our best theories of cosmology have a problem. Though we can build computer simulations<\/a> that do a good job of reproducing the cosmos we see around us, they rely on the presence of dark matter<\/a>.<\/p>\n

This mysterious dark matter, which outweighs normal, visible matter by a factor of 6 to 1, is needed to provide the gravitational heft to form the structure of galaxies<\/a> and galaxy clusters <\/a>but must not interact with light.<\/p>\n

We need something that is massive, and which is dark.<\/p>\n

It\u2019s only natural to think that black holes might be part of the answer.<\/p>\n
