Did you know Earth is about to spin a little faster? This summer, our days will be up to 1.5 milliseconds shorter—thanks to the moon’s shifting gravitational pull. You won’t notice, but scientists are geeking out over it! It’s not the first time, either—Earth’s rotation is always a bit unpredictable, with everything from melting ice to earthquakes playing a part. No need to reset your clocks, but it’s wild to think our planet’s pace is always changing! #Science #EarthScience #FunFact
