A red car blasting David Bowie as it floats around the Earth has become a real bee in the bonnet for the Flat Earth community.

To fill you in on why these cosmographically confused folks are scrambling, on Tuesday SpaceX—the private aerospace manufacturer and space transport founded and run by Elon Musk—successfully launched and landed Falcon Heavy, which was dubbed the most powerful operational reusable rocket in the world. The Falcon’s payload was a red Tesla roadster playing an infinite loop of Space Oddity with a dummy in it, which then floated around the Earth—its final destination is Mars.

The Tesla’s time in the void was live streamed and people quickly used the opportunity to dunk on Flat Earthers. Twitter even made a moment called “Did Elon Musk just shut down the Flat Earth conspiracy?” (Quick tip: the answer to the question is no, Eratosthenes did that like 2,000 years ago.)

Both the non-stop dunking and the clear view of a round Earth understandably peeved off those who adhere to the wisdom of Kyrie Irving. Some are saying that the stunt was actually made to distract people from the fact that Tesla filed their biggest ever quarterly loss recently; others are saying it’s all part of an evil Illuminati plan. Some say that the entire production was computer generated while others are of the belief that it was filmed in a studio a la the moon landing.

The only thing the Flat Earth community seems to agree on though, is that they think the stunt was fake as hell.
