90% of Americans believe at least one conspiracy theory

Probably the biggest conspiracy theory, bigger than ufos and aliens, is the mystery surrounding inventors and physicists that have produced energy efficient motors, zero point energy, anti-gravity, solar energy, etc. All of them filing patents that get slapped with the secrecy label in the name of national security then either disappear or die under suspicious circumstances. I like watching this guy because he shows the conspiracy, then either debunks it or shows that it's still a mystery.
