Will Earth Really Stop Rotating?
"Earth will not suddenly stop rotating. Based on physics and astronomy, our planet’s rotation is gradually slowing down due to tidal interactions with the Moon. This process makes days longer by about 1.8 milliseconds every century.
Scientists estimate that billions of years from now, Earth could become tidally locked with the Moon, meaning the same side of Earth would always face it. But Earth will never just suddenly stop spinning—it’s a very slow, natural process over immense timescales."
