The concept that the Earth is stationary is not accurate according to modern scientific understanding. In fact, the Earth is in constant motion. Our understanding of Earth's motion comes from centuries of scientific observation, experimentation, and analysis.
Here are a few key pieces of evidence that demonstrate the Earth's motion:
Day and night cycle: The regular cycle of day and night is a result of the Earth's rotation on its axis. As the Earth rotates, different parts of its surface are exposed to the Sun's light, causing daylight and darkness to alternate.
Coriolis effect: The Coriolis effect is the apparent deflection of moving objects caused by the rotation of the Earth. This effect is observed in the movement of large-scale atmospheric and oceanic systems. It leads to the formation of global wind patterns, ocean currents, and the rotation direction of cyclones in different hemispheres.
Foucault pendulum: In 1851, the French physicist Léon Foucault demonstrated the Earth's rotation using a pendulum. The pendulum's swing appeared to rotate gradually over time due to the Earth's rotation beneath it. This experiment provided direct visual evidence of the Earth's rotation.
Satellite observations: Artificial satellites orbiting the Earth provide continuous evidence of the Earth's motion. Their orbital paths and velocities are calculated based on the Earth's rotation and gravitational forces, enabling accurate predictions and navigation.
Stellar observations: The positions and movements of stars in the night sky provide evidence of Earth's motion. Over the course of a year, as the Earth orbits the Sun, different constellations become visible at different times, a phenomenon known as stellar parallax. The apparent motion of stars also confirms the Earth's rotation.
These are just a few examples of the extensive scientific evidence supporting the Earth's motion. Modern understanding is based on a combination of observations, experiments, and mathematical models that explain the complex dynamics of our planet's motion within the solar system.
