If a tree falls in a forest, does it really make a sound?

If beans are spilled in a suburban loungeroom, is a conspiracy really revealed to the world?

"Fake Moon Landing" and "Fake Climate Change" are implausible because they are so high-profile, public and trans-national, and "Chemtrails" because burning jet fuel in air is so violently destructive of chemistry.

None of those are implausible purely on the scale required. 

- Katyn Forest was real. 
- Treblinka was real. 
- Nuclear Winter was not real. 
- Eating carrots does not help you see at night (but it was a good cover for the deployment of radar).
