Earth's Day Lengthening: 25-Hour Day a Future Reality, Scientists Reveal

• Scientists predict Earth could eventually have a 25-hour day due to its slowing rotation.
• The Moon's gravitational pull, causing ocean tides and friction, is the primary reason for Earth's rotational slowdown.
• Climate change, melting ice sheets (Greenland, Antarctic), and rising sea levels also contribute to changes in Earth's rotation and axial tilt.
• Earth's internal movements (mantle and core) have a minor, but contributing, effect on its rotational speed.
• Advanced geodesy technology, including atomic clocks and satellite laser ranging, is used to precisely measure these subtle changes.

Why It Matters: Earth's rotation is gradually slowing, driven by lunar gravity and climate change, potentially leading to a 25-hour day in 200 million years.
