the echo chamber 

Public Relations slang for the tactic of repeating some fake factoid so loudly and so often that many people start to believe it. It is even more effective if public figures and celebrities are used in the echo chamber.

This technique was used for years to debunk those who noted the first signs of climate change.

the echo chamber was used for years by the tabacco industry to deny the health effects of smoking.

That is if someone farted and it was loud enough and happened at the right would it make an echo?

One of the unanswered questions of the universe. Sometimes asked by someone who is high on pot etc.

Hey man, does a fart make an echo?
