According to TimeAndDate.com, our globe completed one rotation more quickly than scientists have ever before observed.
On Wednesday, June 29, Earth completed one rotation of its axis in 1.59 milliseconds, or less than 24 hours.
Hold on! Right, the Earth rotates once on its axis in exactly 24 hours. Yes, almost, but not quite.
It had been believed, up until a few years ago, that the Earth's rotation was slowing down as a result of numerous subsequent atomic clock readings made since 1973.
In order to compensate for the slower spin, the International Earth Rotation and Reference Systems Service (IERS) had even started to occasionally add leap seconds (the most recent occurrence was on December 31, 2016).
That may still be the case over a longer length of time; the Earth's rotation may still be generally slowing down.
After all, the Earth's rotation is being slowed down over time by the Moon. Tides are produced by its gravitational pull, and the Earth's orbit is altered.
Atomic clocks have, however, recently revealed that the Earth's rotation is rapidly accelerating.
In fact, a 50-year phase of shorter days may be starting right now.
