The Earth's rotation causes the apparent motion of celestial bodies in the sky, such as the Sun, Moon, and stars. The rotational speed of the Earth at the equator is about 1,670 kilometers per hour (1,040 miles per hour). This rotational speed gives us the perception of a moving sky.

If you were to stand on the Earth's surface and move at the same rotational speed, about 1,670 kilometers per hour, in the opposite direction of the Earth's rotation, you would effectively cancel out the motion and perceive the rotation of the Earth as still. This is known as being in a geostationary orbit, where an object orbits the Earth at the same rate that the Earth rotates.

If you were to go faster than the Earth's rotational speed, the motion of the Earth would appear to reverse. For example, if you were to travel eastward faster than the Earth's rotation, celestial bodies in the sky would appear to move westward. As you continue to increase your speed, the apparent motion of the Earth's rotation would become faster until it eventually disappears altogether.

The specific speed at which the apparent motion of the Earth's rotation disappears depends on various factors, including your location on Earth and the exact direction and speed of your travel. However, it's worth noting that reaching such speeds would require technology and vehicles that are currently beyond our capabilities.
