Most of us want we had greater than 24 hours in a day to get every part completed and really breathe. What if every day gave us greater than double that point? If it wasn’t for a phenomenon that put the lengthening of Earth’s days on pause billions of years in the past, that will have in all probability occurred.

Earth has not all the time had 24-hour days. There have been fewer than 10 hours in a day when the Moon first got here into being round 4.5 billion years in the past, however they’ve grown longer as lunar tidal forces step by step slowed Earth’s rotation. However there was a protracted interval when days didn’t develop in any respect. Astrophysicists have now discovered that, from 2 billion to 600 million years in the past, days had been about 19.5 hours as a result of a number of tidal forces canceled one another out and stored Earth rotating on the identical velocity for over a billion years. If that had by no means occurred, our current days is perhaps over 65 hours lengthy.

“The truth that the day is 24 hours lengthy…will not be a coincidence,” the analysis workforce mentioned in a research lately revealed in Science Advances.
