Web1 day ago · Bob Knodel is one of those proponents of the flat-earth theory. He runs a YouTube channel solely devoted to the idea and is a member of the group using a $20,000 (or Rs 16 lakh) laser gyroscope to demonstrate the earth doesn't rotate. "What we found is, when we turned on that gyroscope, we found that we were picking up a drift," says Knodel. WebThe Ring Laser Gyroscope (RLG) is a consumer device version of the Michelson-Gale-Pearson Experiment (MGP)[1]. The principle of operation of these devices is based on the Sagnac Effect, which was famed for showing that light changes velocity on a rotating platform. In the RLG and MGP experiment the Earth is used as the 'rotating platform'. …

WebMar 14, 2024 · In fact it's considered a kind of benchmark of gyroscope performance. A decent fiber optic laser gyro should do it. Or a ring laser gyro. Earth's rotation about its axis is about 0.004°/s. An MPU-6050 has initial tolerance of +/-20°/s and sensitivities to power supply voltage, temperature etc. that are the order of 0.1°/s for small changes. WebYup, the strength of gravity changes from about 9.78 m/s^2 at the equator to about 9.83 m/s^2 at the poles, mostly because of the spin of the earth and the resulting centrifugal force. Gravity also changes depending on how high up you are: the further you get from the center of mass the lower the gravity. images of wirral waters

WebFlat-Earthers’ laser tests are misleading. They pointed the laser from near the surface toward a distant observer. If the observer sees the beam, they conclude Earth is flat. It was a misunderstanding about laser & how atmospheric refraction affects it. A laser beam diverges and will not stay focused forever.
