Professor Dave Explains's video: Pierre-Marie Robitaille Is Clueless Sky Scholar Debunked

Keeping in the theme of debunking all kinds of cranks and con men in the realm of "alternate cosmology", let's add one more nutjob to the mix. Pierre-Marie Robitaille is a former radiologist who likes to pretend that he understands astrophysics better than astrophysicists. He doesn't. When he talks, he makes ridiculous claims and blatant errors that can be spotted by anyone with a basic understanding of physics and astronomy. Nevertheless, many gullible people speak about him like he's a genius, so I thought I'd explain quite thoroughly how he definitely isn't. If you're someone who has fallen for his lies, please watch.
