Sounds legit. Did he also confirm that the sky is blue?
Nope he actually didn't. He said thesky is actually colorless. The color you see is actually sunlight being diffracted by the gases in our atmosphere. On a clear (non-hazy, non-polluted) day, the sky appears blue. This is due to the high concentration of Nitrogen. However, in a smog clogged city, the sky can appear white to dirty brown. This is due to the high concentration of hydrocarbons. You can even get a red-orange sky if you're near a large fire or if a large volcano has just erupted.
