What are your favorite conspiracy theories?

https://en.wikipedia.org/wiki/Bielefeld_conspiracy because it's harmless. I've been to the city, it does exist (or arguably I'm trying to fool you and I'm part of the conspiracy).

1. The building inspectors were bribed, and thus the World Trade center wasn't actually safe to re-occupy after the bombing in the 1990s. (They might have also been bribed during construction)

2. Belgium actually controls the world.

3. The solution to computer security was developed in the 1970s in response to lessons learned in VietNam, but it has been deliberately pushed aside so the three letter agencies can keep on infiltrating our systems.

4. The entire Cold War was kayfabe, as is much of politics.

5. Antigravity was solved in the 1950s, and is kept secret, along with a whole host of technologies that would make energy essentially free, just to keep selling oil.

6. Tesla was right about tapping the energy of the atmosphere, but it turns out to only be a Terawatt, unlimited back then, but a drop in the bucket compared to modern power use.

7. If you actually knew the complete laws of physics, it would be trivial to build weapons of mass destruction, thus science has been deliberately pushed towards dead ends like string theory.

It's a pretty minor one but I don't know if the company Smarking exists: https://news.ycombinator.com/item?id=27294446

Not a conspiracy theory: Covid leaked from a "gain of function" experiment.

I thoroughly enjoy everything having to do with Bigfoot -- not because I believe any of it for a second, but because the theories around why the government is hiding them from us are fascinating. Its some of the craziest stuff you'll ever hear.

A president of the united states, tried to invalidate the elections and coordinated attacks on the US govt. He got away with it.
