Why Do Our Age Slower In Space? - ScienceNerds

In the movie Superman, there is a famous scene in which the Man of Steel revolves around the planet to go back in time, while the idea is pure comic fiction if someone revolved around the planet, in fact, it would affect time, but only to them.

 Time is relative, which means that the speed of time passes changes based on numerous factors such as gravity or how quickly you move. What this means is that astronauts in space-age more slowly than everyone here on Earth. But why?

Einstein's theory of relativity created the idea that there is a fabric that permeates the entire universe called 'space-time' 'Space-time' does not remain the same, it can be deformed by matter and energy This is called 'dilation of time '.

For example, time moves slower on Earth than in space because the gravitational force of Earth doubles space-time, this is 'gravitational dilation of time' If you were in space away from the gravitational pull of the Earth, You would age faster than someone at home. It is stronger the closer it is to the surface, it means that your feet are younger than your head And a person who lives on the ground would age more slowly than someone who lived on top of a mountain But the difference would be as small as to make it imperceptible.

Time also moves slower the faster it moves, this is 'speed time dilation'. On the twin stage, if one twin remained on Earth while the other twin flew in a rocket through space before returning, the twin in the rocket would meet when he returned. his earthly twin had aged more.

 This is exactly what happens when you have an atomic clock flying on a plane. It will record less time than past than an atomic clock that remains on the ground. So, do we age more slowly in space or not? The answer depends on what you are doing in space. If I were floating in space on Earth and didn't move, I would age faster. But for those astronauts on the International Space Station that buzzes around Earth at about five miles per second, they would actually age more slowly. because its expansion of velocity-time has an effect greater than its expansion of gravitational time. A six-month period aboard the IEE would give you approximately 0.07 seconds of extra life. So, if you want to stay young in relation to other people on Earth, all you have to do is find a way to revolve around the planet at an incredible speed like Superman.
