Time Dilation, like many other things, was a thought, Albert Einstein had. His work was highly influenced by two of the genius scientists namely Isaac Newton, and James Maxwell. Einstein never said ‘everything is relative’. By that, he meant ‘velocity is a property that relates the condition of two objects together; that there is no absolute velocity.’ James Maxwell while working on electromagnetic radiation devised that speed of light is fixed. Einstein’s relativity also sets the speed of light at 300 million meters per second.
Einstein one day while going off from his work, had a wild thought about time. If the speed of light is universal, a person at that speed will notice the field of vision change drastically, but at the same moment will experience that time for him has slowed down. This thought blew Einstein’s head. Either Law of Motions had a blemish or speed of light is not a universal constant. Though Einstein was able to resolve this conflict by devising that space and time are two parts of the same thing. Together they make up space-time where every action takes place. The fast space moves, the more time slows by for it. The center of a gravitational object always has time to run slower, meaning they bend space more.
Time runs faster in space and slower at here on earth, and even slower at the center, with a very tiny unnoticeable difference.
The most famous example of time dilation is imagining a train pass by you. Imagine you see a train pass by you at the speed of 40 km per hour. However, if you see that same train pass by with you sitting on another train which has a speed of 20 km per hour, now that first train you will see has just 20 km per hour of speed. The faster you move, the slower you see time run for you.
Time dilation explains why two working clocks will report different times after different accelerations. For example, at the ISS time goes slower, lagging 0.007 seconds behind every six months. For GPS satellites to work, they must adjust for similar bending of spacetime to coordinate with systems on Earth.
This is a wild thought, but it’s true. Every clock is affected by time dilation, a classic wall clock, a digital clock, or even a precise electromagnetic clock. All of them. And yeah, your biological organs also slow down, you are now older at some point, and younger at some another point.
