@nottoogood: You are right, you can't see them directly. But you can definitely see their black outline against lighter background and the lensing effects of light bending space curvature around them. And materials being sucked into them form discs so the above image is a very good representation of what a black hole might look like.
ill look past the fact you cant see black holes . because this is awesome as fuck :) nice work
indeed thats why its awesome was just talking about the middle .. but i has to be represented in some form so it was done well :)
