Scientists have found the Earth is spinning faster than normal, rotating its fastest since the 1960s.
Measurements by the UK’s National Physical Laboratory revealed the Earth is spinning faster than it was half a century ago.
June 29 marks the record-breaking shortest day, the Earth’s full rotation took 1.59 milliseconds less than 24 hours – the shortest day recorded since scientists began using atomic clocks to measure the Earth’s rotational speed.
Astrophysicist Graham Jones said if the rotation rate continues to speed up – our atomic clocks may see the removal of a second.
“If Earth’s fast rotation continues, it could lead to the introduction of the first-ever negative leap second,” he said in a report to TimeandDate.com
“This would be required to keep civil time – which is based on the super steady beat of atomic clocks – in step with solar time, which is based on the movement of the Sun across the sky.”
The Guardians reports over the past years, scientists have seen a range of records fall – with shorter days being notched up more frequently.
In 2020 TimeandDate.com reported that the Earth had achieved its 28 shortest days, with July 19 2020 taking 1.47 milliseconds less than 24 hours for the Earth’s full rotation.
