Why Don’t We Feel the Earth Move?

See chronicleThe Earth stands still at the center. The Moon, the Sun, Jupiter, and Saturn roughly circle it, and Mercury, Venus, and Mars go around the Sun on Kepler’s ellipses, so they fit Tycho’s measurements.
Gamma Draconis, and the other stars I’ve measured, shift back and forth over the year by about 20 seconds of arc, always toward the direction the Earth is moving in at the time. Light takes time to arrive, and the Earth’s motion slants the direction it seems to come from. A motionless Earth can’t produce this.
A long pendulum’s swing turns slowly clockwise, about 11 degrees an hour in Paris, though nothing pushes it sideways. The floor beneath it turns, with the spinning Earth. A motionless Earth can’t explain this.
