No experiment has ever been performed with such excruciating persistence and meticulous precision, and in every conceivable manner, than that of trying to detect and measure the motion of the Earth...
... except the experiments that did but you would like to deny them and erase them from history.
Just one of the simple examples: the Foucault. 
Foucault? ROFLMAO
Foucault pendulum is a hoax. All modern Foucault pendulum displays are driven by finely tuned electric motors, tuned according to Foucault’s own formula for pendulums at latitude, and therefore demonstrate nothing scientific. It does however create a context of vicious circular reasoning.
The motors found in museum Foucault pendulums involve an electromagnet ring that surrounds the wire holding the pendulum weight. The objective of the ring magnet is to draw the pendulum wire away from its center position, with a pulsating magnetic field, so that the pendulum swings without slowing under frictional forces. The problem with this electromagnetic setup is that the ring magnet induces current into the pendulum wire, and like a modern squarel-cage motor, the wire returns an opposite magnetic field almost perpendicular to field of the ring magnet, but with a very small inductive delay. This interaction of magnetic fields causes torque in the wire. That is, the wire rotates slightly as a result of these magnetic interactions, so that the magnetic interactions and resulting electromagnetic-propelled precession, fabricate the illusion of a working Foucault pendulum.
The problem with Foucault’s premise
Foucault’s premise for the pendulum is as follows: Suppose you swing a pendulum over a table and you rotate the table slowly. The pendulum will stay in line as the table turns. But if you sit on the table as it turns: the pendulum itself will appear to rotate. The pendulum, Foucault said, is "fixed in absolute space while, like the table, we and the planet rotate under it." The pendulum appears to us to turn slowly as it swings back and forth but it is really we who are rotating around the pendulum.
The problem for this premise is as follows: if the earth is spherical and rotating, then the only place where the pendulum can function as prescribed by Foucault, “"fixed in space”, is at a pole (and held by something external to the earth). At a further latitude on such a rotating earth, the component of the earth turning under the pendulum is so diminished, so that the dominating force on the pendulum would be the centripetal force of the earth rotating. That is, the premise for the Foucault pendulum can only apply at (or near) a pole. However, the Foucault pendulum experiment was conducted in France, which is nowhere near the pole.
According to Elmendorf’s own attempts to reproduce Foucault’s experiment, “the Foucault pendulums seldom achieve turning rates closer than 15 percent to the theoretical. Compared to a sundial their daily movements are a joke, swinging in erratic directions proving that it is not an instrument controlled solely by the supposed steady rotation of the earth underneath it, but that the sensitive bob is moved by other unknown inertial influences” (Elmendorf, Foucault Pendulum, Pittsburgh Creation Society).
There is no physical or logical reason to put the pendulum in motion:
If the pendulum is indeed "fixed in absolute space”, then there is no need to rock the pendulum, because the frame of the earth would rotate beneath a stationary pendulum weight, anyway. One could just as easily have a large disk sitting with a flat side to the ground, and suspended on a frictionless magnetic-field bearing. If indeed the earth is rotating, then the disk should, according to Foucault’s own reasoning, also rotate. We do not observe this affect in any such cases.
In fact, if Foucault’s pendulum premises were valid, we could use the earth’s rotation to generate electricity, and solve the world’s energy problems. The fact that energy generation through the earth’s rotation, and Foucault’s premise, is not even being explored, is telling of the nonsense that is the Foucault pendulum.
Foucault’s approach was not even scientific, because he believed the earth was rotating, he created and peddled his pendulum experiment to support his belief through the fallacy ad populum. The Foucault pendulum experiment is Foucault’s confirmation bias. If his approach had been even remotely scientific, Foucault would have devised experiments to falsify his hypothesis, as opposed to confirming it.
Alas, Foucault’s pendulum is a hoax...
No experiment has ever been performed with such excruciating persistence and meticulous precision, and in every conceivable manner, than that of trying to detect and measure the motion of the Earth...
BTW, what else could be the reason for different weight reading of the same object on the same scale at diferent latitudes (distances from the Earth's axis)?
