Seriously?Life is not measured by the number of breaths you take, but by the moments that take your breath away.

On 29 June this year, Earth racked up an unusual record: its shortest day since the 1960s, when scientists began measuring the planet’s rotation with high-precision atomic clocks.
Broadly speaking, Earth completes one full turn on its axis every 24 hours. That single spin marks out a day and drives the cycle of sunrise and sunset that has shaped patterns of life for billions of years. But the curtains fell early on 29 June, with midnight arriving 1.59 milliseconds sooner than expected.
The past few years have seen a flurry of records fall, with shorter days being notched up ever more frequently. In 2020, the Earth turned out 28 of the shortest days in the past 50 years, with the shortest of those, on 19 July, shaving 1.47 milliseconds off the 86,400 seconds that make up 24 hours. The 29 June record came close to being broken again last month, when 26 July came in 1.5 milliseconds short.
(...)Analysis: Reflecting a recent trend, 29 June was the shortest day on our planet since the 1960s. What’s going on?
Earth is spinning faster and faster. If the trend continues this way there will be a point when the centrifugal force becomes so strong that we'll all fly off the planet!

There's probably a large block of dense crust subsiding deep into the mantle.Indifference is Bliss

You seem awfully well informed about this

It's just a wild guess. Oceanic crust gets denser as it ages (and is denser than continental crust), and often large chunks stay surprisingly together after subducting into a fault. I'm not at all aware of what they do once they've done so, and whether my theory is at all valid or not.
