:P And the black hole has been observed?

Oh.. my mistake. We don't observe things directly in cosmology anymore. We observe other things that we don't understand and invent things to explain them. Isn't that what the Ancient Greeks did with thunder?

Only partially sarcastic here, though. All these articles and theories of Black Holes, Dark Matter, and Dark Energy are starting to sound a lot like Zeus, Hades, and Poseidon.

The sound of laughter........
