One day, total solar eclipses will vanish from Earth forever.
One day, total solar eclipses will vanish from Earth forever. Not because of anything dramatic — just because the Moon is slowly leaving us.
Every year, it drifts about 3.8 centimetres further away. Tidal forces between Earth and Moon are doing this quietly, continuously, and there is nothing to stop it.
The same process is stealing time from our days. That gravitational tug is gradually slowing Earth's spin. Hundreds of millions of years ago, a day here lasted only around 22 hours. We have been gaining seconds, slowly, ever since.
As the Moon retreats, it shrinks in our sky. Eventually it will appear too small to cover the Sun completely. That perfect cosmic alignment — the kind that turns day into sudden darkness — will be gone.
We live in the window where it still happens. Follow Deep Field Vault for more of the universe while we still can.
