October 4, 20242 Mins Read
The journey of time has started since the creation of the universe. Since then, time has only moved on, never stopped. Time cannot be controlled. So the importance of time in human life is immense. But time does not run equally everywhere. Somewhere fast, somewhere slow. All these can be explained with the help of science. Let's know 5 facts about this strange behavior of time.
the time
People have been counting time for thousands of years
Scientists recently discovered the world's oldest calendar. The 13,000-year-old calendar was discovered in the Gobekli Tepe region of Turkey. People of that time created this calendar to record the date of a comet hitting the earth. This is the oldest known calendar in the world. As such, people have been keeping track of time for thousands of years.
None of us live in the present
Whatever we see is the past. The sun that I see in the eastern sky in the morning is also the past. Because we see it about 8 minutes and 20 seconds after sunrise. That is, if the sun disappears suddenly, we will perceive it after 8 minutes and 20 seconds. You are also seeing the past image of a person standing 10 feet away from you. No matter how short it is!
Not a day in 24 hours
By day we usually mean 24 hours. This calculation is also easy to understand. In fact, a day refers to the time it takes for the earth to rotate once on its axis. Earth currently rotates around its axis once every 23 hours 56 minutes 4.2 seconds. That is, one day is 23 hours 56 minutes 4.2 seconds, not 24 hours.
Dinosaurs had a year of 370 days
Dinosaurs ruled the earth about 66 million years ago. Dinosaurs could have reigned about 5 days longer in a year than today. Because then the year was 370 days. Day length increases by only 1.7 milliseconds every 100 years. One thousandth of a second is called a millisecond. As a result, the length of the year is reduced to 365 days.
Seconds don't mean what you know
Usually we call 60th of a minute as a second. But scientifically it is not the definition of a second. For ease of understanding, we call 60th of a minute as a second. Historically, a time of 8 lakh 64 thousand parts of a day is also called a second. But scientifically, the time it takes for an unexcited cesium 133 atom to complete 9,192,631,770 vibrations at zero Kelvin temperature is called one second.
