Take something like Flat Earth Theory. Okay, if that's real, how can you do something different and gain benefit from it? Can you create an airline service with quicker flights to certain destinations?

I was just reading a conspiracy theory about how the The Great Pyramid was actually a device to change the magnetic poles. Okay, can we recreate it to change the poles again?

What are some conspiracy theories that if true can actually lead to us doing something different? How can we benefit from knowing the "truth"?
