The Coral That Remembered the Ancient Moon

Did Earth once have 400 days in a year? And can a fossil coral reveal that the Moon was once closer to Earth?

🌍 In this episode of Cosmic Curiosity Lab, we explore one of the most beautiful connections between biology, geology, and astronomy.

🪸Hundreds of millions of years ago, ancient corals recorded daily growth lines inside their skeletons. When scientists studied Devonian fossil corals, they discovered that a year once had around 400 days — meaning Earth was spinning faster, and each day was shorter.

🌜But what does that have to do with the Moon?

🌊Through tides, Earth’s rotation, and the slow transfer of energy between Earth and the Moon, scientists can understand why the Moon was once closer to our planet — and why it is still moving away today.

🌌This is a story about fossil corals, ancient oceans, lunar laser ranging, Apollo retroreflectors, and the deep connection between life and the cosmos.
