Did you know that the Moon, Earth's buddy in the sky, is slowly moving away from us? This interesting event is happening because of the way gravity works between the Earth and the Moon

The Moon drifting away is like a game of tug-of-war played by gravity. You see, the Moon's gravity pulls on Earth, creating tides in the oceans. Earth's spin tries to counteract this by making another bulge on the opposite side. Over a really long time, this tug-of-war makes the Moon move into a higher orbit


This moving-away process is due to something called tidal acceleration. As the Moon makes tides on Earth, gravity wants the Moon's spin to match how it goes around Earth. This causes the Moon to always show the same side to Earth, and at the same time, it moves into a higher orbit. That's what we mean by the Moon drifting away


Right now, the Moon is moving away at a speed of about 1.5 inches each year. It sounds tiny, but over a super long time, it adds up. Scientists say about 1.4 billion years ago, the Moon was way closer to Earth


As the Moon moves away, it has a small effect on how fast Earth spins. This makes our days a tiny bit longer, but don't worry, it's just a few milliseconds every century. Even though we can't feel it, it shows us that our Moon and Earth are always changing


The Moon moving away is like a slow dance happening in the sky. This gentle journey reminds us that things in space are always moving and changing. So, next time you look up at the Moon, remember it's on a quiet trip away, showing us the amazing forces at play in our cosmic neighborhood


Due to this difference, "the reproductive system of women will stop working"
