Nurtle on Instagram: "A group of flat earthers led by Bob Knodel set out to prove once and for all that Earth is flat, spending $20,000 on high-end equipment to test their theory. The experiment was filmed for the Netflix documentary Behind the Curve. They used a ring laser gyroscope to measure Earth’s rotation, expecting no movement if the planet was flat. Instead, the device immediately showed a 15-degree per hour drift, exactly what scientists predict for a rotating globe. The group was visib
