Experts searching for answers as earth spins faster and midnight comes early

It normally takes the earth exactly 24 hours to rotate once on its axis, but on June 29, the earth recorded its shortest day since records began and now scientists are searching for an answer.

It completed one rotation in 1.59 milliseconds under 24 hours. Then, the June 29 record came close to being broken last week.

On Tuesday, July 26 came in 1.5 milliseconds short. Although experts have yet to find the exact reason for this, there are a number of theories being circulated.

Some have suggested it could be due to the melting of glaciers or the accumulation of large quantities of water in northern hemisphere reservoirs.

Others say it could be due to seismic activity or the motions of the planet's molten core. Scientists also warn the faster rotation of the earth could have concerning consequences.

The most serious implications would reportedly be on technology such as GPS satellites, smartphones, computers, and communication networks, all of which rely on extremely accurate timing systems.

If a leap second occurs, the clock would change from 23:59:58 to 00:00:00, which Meta predicts could have a "devastating effect on the software relying on timers or schedulers".

To compensate for the change, a negative leap second may be needed by the world's timekeepers in order to help balance the clocks and keep GPS technology which relies on precision timekeeping intact.
