I didn't know we had experiments which could detect rotation or movement of the Earth?
When Flat Earthers Spent $20,000 Trying To Prove Earth Is Flat And Accidentally Proved It's Round
One of those Flat Earthers is Bob Knodel, who hosts a YouTube channel entirely dedicated to the theory and who is one of the team relying on a $20,000 laser gyroscope to prove the Earth doesn't actually rotate.
Except... It does.
Flat Earthers spend $20,000 to prove the Earth is flat, end up proving it’s round
One of the more jaw-dropping segments of the documentary comes when Bob Knodel, one of the hosts on a popular Flat Earth YouTube channel, walks viewers through an experiment involving a laser gyroscope. As the Earth rotates, the gyroscope appears to lean off-axis, staying in its original position as the Earth’s curvature changes in relation. “What we found is, is when we turned on that gyroscope we found that we were picking up a drift. A 15 degree per hour drift,” Knodel says, acknowledging that the gyroscope’s behavior confirmed to exactly what you’d expect from a gyroscope on a rotating globe. “Now, obviously we were taken aback by that. ‘Wow, that’s kind of a problem,’” Knodel says. “We obviously were not willing to accept that, and so we started looking for ways to disprove it was actually registering the motion of the Earth.”
All the most modern research we have conducted in our physics of the Cosmos indicates that we are living in a vastly complex, almost infinitely powerful simulation of Reality. I

Interesting, has the experiment been verified and repeated?
Earth rotation measured by a chip-scale ring laser gyroscope
Optical gyroscopes are among the most accurate rotation measuring devices and are widely used for navigation and accurate pointing. Since the advent of photonic integrated components for communications, and with their increasing complexity, there has been interest in the possibility of chip-scale optical gyroscopes1. Besides the potential benefits of integration, such solid-state systems would be robust and resistant to shock. Here, we report a gyroscope using Brillouin ring lasers on a silicon chip. Its stability and sensitivity enable measurement of Earth’s rotation, representing a major milestone for this new class of gyroscope.
Earth Rate Precession
Earth rate precession is caused by the rotation of the earth while the spin axis of the gyro remains aligned with a fixed point in space. Earth rate precession is divided into two components. The tendency of the spin axis to tilt up or down from the horizontal plane of the observer is called the vertical component. The tendency of the spin axis to drift around laterally; that is, to change in azimuth, is called the horizontal component. Generally, when earth rate is mentioned, it is the horizontal component that is referred to, since the vertical component is of little concern.
A gyro located at the North Pole, with its spin axis initially aligned with a meridian, appears to turn 15.04° per hour in the horizontal plane because the earth turns 15.04° per hour. [Figure 14-10] As shown in Figure 14-10A, the apparent relationship between the Greenwich meridian and the gyro spin axis changes by 90° in 6 hours, though the spin axis is still oriented to the same point in space. Thus, apparent precession at the pole equals the rate of earth rotation. At the equator, as shown in Figure 14-10B, no earth rate precession occurs in the horizontal plane if the gyro spin axis is still aligned with a meridian and is parallel to the earth’s spin axis.
