I looked at this page. As one of my physics teachers would have said, "No, this isn't right. This isn't even wrong."

This guy knows just enough about black holes to sound like he knows what he's saying. But so much of the content is so utterly and absolutely wrong it boggles the mind.

And his claim that "These behemoths are believed to exist at the center of all solar systems..." is almost right but entirely incorrect. Instead of solar systems, he should have said galaxies. The sun is at the center of our solar system.

I just wish he'd left an e-mail address so this old astronomer could grade his essay. He gets a D and two weeks of detention during which he'll write repeatedly on the board, "I shall not post to the internet if I don't know what I'm talking about."
