We all know that it usually takes exactly 24 hours for the earth to complete a complete rotation on its axis. A scientist at the UK’s National Physics Laboratory has warned that the Earth is spinning faster now than it was half a century ago.
The Earth has an average of 86,400 seconds a day, although they may not always be perfect. Sometimes, the pace will increase or decrease in a year. The result will be one or two seconds more or less. These are affected by various factors such as the center of the planet, the oceans, the lunar eclipse, and the atmosphere.
Scientists have used atomic clocks to accurately measure the time it takes for the earth to rotate, based on how electrons in cesium atoms return to higher energy, normal state. It is noteworthy that atomic clocks are never affected by external changes such as temperature changes as conventional clocks.
