The world broke the record for the shortest day since the invention of atomic clocks. On June 29, 2022, our planet completed a normal rotation of about 24 hours, 1.59 milliseconds faster than usual. However, we thought that the rotation of the Earth was slowing down. So what's going on? Is the world speeding up and down? Sort of like that... The world is wobbling.! Moreover, in order to fix it, There is nothing to do; liking, sharing, and commenting on this video won't be enough. As a matter of fact, there is no such extraordinary situation that can be fixed. It's enough to know that a day is not actually 24 hours, it rotates at different speeds in some periods, so adjustments are made on a per second basis from time to time. If these adjustments are not made, then things can get messy. Did you know that in the time of the dinosaurs, a year lasted 372 days? A day was 23 hours and 31 minutes back then. So the world was spinning much faster. 600 million years ago, a day was only 21 hours. I think those who say '24 hours is not enough for me at all' should think again. When you watch the planet's millions of years of history, we see that its rotation is gradually slowing down. One of the biggest reasons for this is the Moon. The force of tidal currents between our planet and this natural satellite orbiting it. Yes, although we love the Moon very much, its presence unfortunately slows down our rotation. But its effect on slowing us is not constant, it also changes. Because our beloved satellite is getting farther and farther away from us. Its orbit is moving further by 3-4 centimeters each year..
Scientists made some very interesting observations a few years ago. They realized that the Earth, whose rotation had been slowing for millions of years, suddenly started to speed up. 28 of the shortest days in the last 50 years have occurred in 2020 alone. Take a look at the oscillation in this graphic. All in the same year.
They measured that on July 19, 2020, a day took 1.46 milliseconds shorter than usual. Of course, this is the previous record. The real record was broken this year.
With 1.59 milliseconds on the 29th day of June. If you ask, how long is this millisecond, I can show you this. The indicator right next to the hour, minute and second marks. So that's a very, very short time. To make it even more visual, blink now. June 29 was one blink of an eye shorter than usual. Atomic clocks have been used since 1949 to make such precise measurements.Since it is a type of clock that measures time by counting the resonance frequencies of atoms, very sensitive data can be obtained from them. These clocks have a margin of error of at most one second in 300 million years. This is how they find that the rotation speed of the Earth, which normally slows down, suddenly increases, even on a millisecond basis. So why did this rotation suddenly start to gain momentum like this all of a sudden?
