Research shows that for about a billion years, Earth's day lasted around 19 hours due to a balance between lunar tidal forces and atmospheric tides, with long periods of stability interrupted by episodes of faster or slower rotation, influencing Earth's climate and oxygen levels over geological time.

Scientists in the US have developed a device that can generate tiny amounts of electricity by harnessing Earth's rotation and magnetic field, suggesting a potential, though currently impractical, new energy source if scaled up. The experiment involved a specially shaped ferrite shell that avoids the usual cancellation of voltage caused by electromagnetic forces, producing measurable microvolts as Earth spins. While promising, the technology is in early stages, and further independent testing is needed to verify and explore its scalability.

Flying against Earth's rotation does not speed up flights because objects and atmosphere move with the Earth due to inertia and frictional forces, and jet streams—fast-moving air currents influenced by Earth's rotation—affect flight durations more than the Earth's spin itself.

Earth's days are slightly getting shorter due to factors like atmospheric winds, ocean currents, Earth's internal movements, and lunar gravitational pull, with the shortest day on August 5, 2025, measuring just 86,399.99867 seconds. These tiny variations, measurable with precise instruments like atomic clocks and quasars, impact systems like GPS and are influenced by both short-term weather patterns and long-term geophysical processes.
