When there will be only 59 seconds in a minute, time will go backward, but when will this happen? let’s find out

Imagine if time goes back. What will happen if the hands of your clock go backward? You might wonder why this would happen? In fact, for the first time in history, attempts are being made to do this, because the Earth is rotating somewhat faster than before. We all know that time around the world is determined by the speed of the Earth’s rotation. But in the last few years, the speed of the Earth has become so fast that scientists are thinking of turning back the hands of the clock by one second. Let us understand what is this whole matter after all?

According to the report of New York Post, a research was published in Nature Journal on March 27. It says that around 2029 the clocks can be turned back one second. This is called negative leap second. This will be a time when the entire world will have 59 seconds instead of 60. This would be an unprecedented situation. However, experts fear that doing so could mess up computer programs around the world.

this is how time is decided
In fact, before 1967, the Earth’s rotation on its axis was used as the basis for measuring time. Scientists first started using atomic clocks in 1967. These clocks use molecules to tick-tock. This made the estimation of time more accurate. But even today many sailors and seafarers depend on the movement of the Earth and the timing of the Moon and the Sun. The speed of both is never the same. That is why whenever a difference of 0.9 seconds is measured between the two clocks, a ‘leap second’ is added. In this way, 27 leap seconds have been added since 1972.

the speed of the earth increased
Now the speed of the earth has become faster than the atomic clock. That’s why coordination is not happening. Now to maintain coordination, scientists are thinking of turning back the hands of the clock by one second. However, this is not going to be so easy. According to University of California researcher Duncan Agnew, such an experiment has never been done before. Therefore there will be more challenges. All computer programs understand leap second to mean only positive leap second. Changes will have to be made in all those programs. This is definitely not going to be easy. But when will this happen? According to Duncan Agnew, if there was no impact of climate change, negative leap second would have to be implemented only in 2026. But now it can be done only around 2029.
