Earth will spin faster today to create 2nd-shortest day in history

Our planet has been rotating at its fastest since records began in 1973.

        I used to think that those recovery questions are stupid, but no. The user is the stupid one, entering the expected information. A few years ago I just decided to enter another generated password in each of the recovery questions, and store them alongside the main one in my password manager. Yes, the school I attended in the fourth grade was nVKuq&zo5BiCOc*0JY5JZHsgRPqcJEumBKV5tt%uSk#acN60s!uLh5MIGwobA3YyHIq3dQxm8r0Yhloloc&3a3BLm!nNbAZ%Vzut - it’s worked for every site I’ve tried it on, too.

        Uno reverse the hackers, 4 passwords instead of 1. 😎

          Nice. My bank lets me pick my own questions, too. The answers are a transformation of the question which, itself, is just some ASCII. My wife uses the same login for the bank, and she hates it.

          Now, you got me thinking. I could make the questions cryptographic hashes that I decrypt to an answer. My wife is going to kill me.

    Saved you a click:

    “The cause of this acceleration is not explained,” Leonid Zotov, a leading authority on Earth rotation at Moscow State University, told Timeanddate.com. “Most scientists believe it is something inside the Earth. Ocean and atmospheric models don’t explain this huge acceleration.”

    Zotov predicts Earth’s rotation may soon decelerate once again. If he’s right, this sudden speeding-up could prove to be just a temporary anomaly in the planet’s long-term trend toward slower rotation and longer days.

    “Something” in the core is “happening” “in a way” that’s speeding us up. Temporarily.

    This is just minor trivia in Earth’s history. 🤷‍♂️

    According to a 2023 study, a day on Earth was approximately 19 hours for a significant part of Earth’s early history

    That headline plays fast and loose with “history” — history supposedly started in 1973?

    Pedantry time!

    When they talk about this stuff they really need to specify which “day” they’re talking about, or else for places that do so, the day the clocks go forward is the shortest day in a year with no others being close.

    From another viewpoint, all rotations relative to the non-Sun stars - aka sidereal days - are still shorter. The daily movement along our orbit around the Sun contributes an extra four minutes to make up the full 24 hours.

    And so, they must be talking about the solar day. They do say 24 hours after all. Or must they? The discrepancy in the nearest sidereal day will be almost exactly the same, and that rounds to 24. So for which day was the lacking one-and-a-bit milliseconds calculated for?

      There’s another factor - days where thr earth is orbiting faster, eg on the closer side of the ellipse - are a different length midday to midday from when we are on the far side of the ellipse.

      You can convince yourself of this when you consider that the area of the arc we traverse each day is the same (Kepler’s law). On the short side of our eliptical orbit, since the orbital distance is shorter, the arc must have a larger angle that we travel. That means the amount a point on the earth rotates to have the sun come back directly overhead must be different in different parts of the year.

      This difference, summed day over day, results in a +/- 20 min movement of actual midday to 12pm. The ‘mean’ in Greenwich Mean Time refers to averaging this difference over the whole orbit.

    There’s some strangely backwards science in there for a website with such a prominent domain, I wonder if it was AI generated.
