When life appeared on Earth, the sun shone 30% less than it does today. How did it survive at that time from the global glaciation? An interesting study suggested, perhaps thanks to the moon’s massive tides that were much close to that.
René Heller Imagine a world where a moon 15 times larger than it is today crosses the sky in just a few hours, scattering gods and quadrants in quick succession. A world in which day and night last only 70 minutes, as the Earth rises and falls several hundred meters in half an hour. And where the ocean rises on the coasts at the same hellish rate at an altitude of more than 1,000 meters … this nightmarish world may have been our world. “When the moon formed, about 70 million years after the beginnings of the solar system, it was much closer than it is today and the Earth was spinning much faster,” explains Rene Heller, of the Max Planck Institute for Solar System Research (Göttingen).
