Yes, just like Hamilton as he turns a corner, our world is speeding up. The Earth has been rotating on its axis more quickly than usual since 2020 (for reasons that are yet unclear), and the next record is set to occur, therefore astronomers are looking into it.Astrophysicist Graham Jones, who is researching this phenomenon, has identified three potential dates for the next shortest day: July 9, July 22, or August 5, 2025.
Hold on, the day will be shortened by 1.66 milliseconds, but it doesn’t mean you’ll work one less day. Not barely a blink’s duration!
Naturally, the reason this is occurring—despite the fact that there are a number of theories on the table—is more significant than the duration of the day.What’s even more intriguing, you ask?The planet was rotating more slowly until lately!
Why is the day getting shorter?
All right, so a solar day should last precisely twenty-four hours, or 86,400 seconds. We are aware of that, yet the Earth’s rotation has never been precise or entirely consistent. As we previously stated, the world appeared to be spinning more slowly until recently (because of the friction of the tides brought on by the Moon’s gravity). However, for some reason, everything changed in 2020, and our globe started spinning more quickly, as though it were in a hurry.
Record after record since 2020
What was once the exception has now become the standard. There was a day in 2021 that was 1.47 milliseconds shorter than usual. It was lowered by 1.59 milliseconds in 2022. The value was 1.31 milliseconds in 2023. However, July 5, 2024, set the absolute record with a day that was 1.66 milliseconds shorter than the typical 24-hour period!
It’s not that a man has a stopwatch, of course, but atomic clocks can measure the duration of our days with millimetric accuracy; otherwise, people would not have noticed at all.
What is causing this acceleration?
Although scientists are unsure of the exact cause, the dates that scientists have projected for 2025 do align with the periods when the Moon is at its furthest point from the equator, which has an impact on our planet. However, its exact etiology has not been established.
A day on Earth might have lasted anywhere from three to six hours 4.5 billion years ago, but the Moon’s gravitational pull decreased Earth’s angular momentum, transforming days into what they are now, according to studies. The Moon has been slowing Earth’s rotation for billions of years.
Is it serious that the day is shorter?
We may believe that a few milliseconds have little bearing, but in the realm of technology and communications, every minuscule second matters. Hopefully, the world won’t collapse in less than two milliseconds because global synchronization systems are made to function with the utmost precision.
What will happen in the distant future?
If this tendency continues, scientists predict that in roughly 50 billion years, the Earth’s rotation will align with the Moon’s orbit, eliminating tides (goodbye surfing), and humans would only be able to see half of the world. Just like when our Sun cools down and the Earth becomes inhospitable, we won’t be around to witness it. Issues for ourselves in the future, or perhaps not!
However, keep in mind that there are still thousands of years left before Earth ends, and by then, our amazing researchers will have undoubtedly already discovered a solution on another planet, like in Wall-E! It’s not like the world is going to stop entirely and throw us out into space, which would be disastrous! Don’t you think that fearing it isn’t worth it for us, the modern humans? To narrate the story, we won’t even be physically present!
