Perhaps this is a fact that many of us do not realize. extra second It was the impact it had on our world.

Yes, you heard right; We experienced 2016 for 1 second longer. So how did this happen?

As we move from 2016 to 2017, the clocks change from 23:59:59 to 23:59:59; It showed 23:59:60.

The world of science It says “leap second”. Yes, maybe no one felt this second, but this meant that the Earth’s orbit lagged behind by about a second. Scientists explain this situation with standard clocks lagging behind atomic clocks.

atomic clocksThey measure time using the change in energy levels of electrons, and the accuracy of these clocks is much better than that of normal clocks.

But Small changes in the Earth’s rotation speedwhich can sometimes cause a discrepancy between atomic clocks and standard clocks.

This discrepancy is very important in precise time measurements such as GPS.

Scientists, rotation speed of our planet They knew that it changes over time and that these changes can affect the measurement of time. For this reason, “extra seconds” were added to the time to compensate for the difference between Coordinated Universal Time (UTC), International Atomic Time (TAI), which regulates the international time standard, and UTC, which is based on Earth time. rotation speed.

world times in 2016 set to UTC and another leap second had been added to midnight. As we all said “welcome” to the new year, we didn’t even realize that we lived the year a second longer.

What caused such changes in the Earth’s rotation speed?

This situation, gravitational effects, atmospheric phenomena and even movements within the Earth’s interior It is caused by several factors such as. This causes ‘leap seconds’.

We haven’t experienced anything like this since 2016. But perhaps more so in the coming years we need extra seconds It will happen.
