Rotation of Planets & Inertia

According to current knowledge, the speed of rotation of the planet corresponds to the momentum obtained during its existence. A gravitational experiment that records a change in the direction of gravitational acceleration on the Earth's surface casts doubt on this knowledge. Analysis of the measured data showed that the Earth's gravitational field is rotating. This means that the cause of the Earth's rotation is not the momentum gained during its existence, but the torque that the Earth continuously receives from the rotation of the gravitational field.
