My first thought about it was that it's awesome. The sad thing is that my second thought about it was that if somehow physics became political, this guy would be banned from Youtube for "physical misinformation" - after disagreeing with a renown expert in the field - and maybe we would never found out about it.

But, apparently, there's a way for people to disagree about science - without any of the sides being evil or stupid - and there's a way to find out who's right. Maybe we could learn something bigger from this?
