The Moon is slowly drifting away from Earth at a measurable pace
In short: Our lunar neighbor isn't staying put. This video explores the physics of why the Moon is retreating and what the long-term consequences are for our planet's rotation and celestial cycles.
The Moon began its journey following a violent impact with a body called Theia roughly 4.5 billion years ago. Since then, tidal forces have been pushing it outward at a rate of about 1.5 inches per year. This movement is measurable through Apollo laser data and fossil coral evidence.
As the Moon moves further away, it alters Earth's rotation, gradually lengthening our days. The video also examines how this drift will eventually impact terrestrial oceans and conclude that total solar eclipses will not be a permanent fixture of our future sky.
