Earth's Rotation Slowing: Will Days Become 25 Hours Long?

• Earth's rotation is gradually decelerating, making days longer by milliseconds per century.
• A 25-hour day is a distant possibility, estimated to occur in approximately 200 million years.
• The Moon's gravitational pull, causing tidal friction and its gradual recession (3.8 cm/year), is a primary factor.
• Mass redistribution from climate change (melting ice in Greenland, Antarctica, rising sea levels) and Earth's internal movements also contribute.
• Scientists use advanced techniques like quasar radio signals and satellite laser ranging to precisely measure these subtle changes.

Why It Matters: Earth's rotation is slowing due to natural forces and climate change, but a 25-hour day is millennia away.
