The earth rotates faster: time flies in the record of 50 years

What if the feeling that time flies is actually true? Indeed, the Earth has been spinning abnormally fast lately, reports The Telegraph. The planet now completes its rotation in 1.4602 milliseconds less than the usual 86.400 seconds. The speed of the Earth’s rotation varies constantly due to the complex motion of its molten core, oceans and atmosphere, as well as the effect of celestial bodies such as the Moon. The friction of the tides and the change in distance between the earth and the moon cause daily variations in the velocity that the planet rotates on its axis, reports the Telegraph, adding that even the snow that builds up on the mountains and in summer melt. move the rotation. July 19, 2020 was recorded as the shortest day since records began in the 1960s after highly accurate atomic clocks were developed, comparing the length of a standard day with fixed stars in the sky. The Telegraph, the previous shortest day in 2005 was beaten 28 times in 2020, and the expectation is that 2021 will be the fastest year ever, with the average day passing 0.5 milliseconds faster than usual. The planet is accelerating and a negative leap second will soon be needed so atomic clocks can connect correctly to the spinning world, and this would be the first time ever that a second of global clocks is removed.

“It is absolutely correct that the earth is now spinning faster than ever in the last 50 years,” said Peter Whibberley, senior researcher at the National Physical Laboratory’s Time and Frequency Group. The Telegraphand adds that ‘it is quite possible that a negative leap second will be needed if the earth’s rotational speed continues to rise, but it is too early to say whether this is likely to happen.’ ‘There are also international discussions about the future of jumping. seconds, and it is also possible that the need for a negative leap second may end the decision to end the end of leap seconds forever. ‘min. more than 24 hours. In the course of 2021, the atomic clocks are expected to accumulate a delay of approximately 19 milliseconds. Although it will take hundreds of years before the difference becomes clear to most people, modern satellite communications and navigation systems are. trust that the time corresponds to the conventional positions of the sun, moon and stars. It is the task of scientists and officials of the International Earth Rotation Service, in Paris, to monitor the planet. s rotation and informs countries when seconds should be added or removed seconds six months in advance.
