What is the difference between time on Earth and in space?

Time on Earth changes from space, it even varies between being at the bottom of the sea and at the top of a mountain, it’s faster at the top of the mountain, while much slower at the bottom of the sea, it’s a strange detail but it really raises the question about the difference between time on Earth and anywhere else In the universe, this is what we are talking about according to the opinions of scientists about time as stated by the site “Void“.

In the seventeenth century, the physicist Isaac Newton saw time as an arrow going off an arc, traveling in a straight line and never veering off course. For Newton, one second on Earth was the same as that second on Mars, Jupiter, or deep space.

In 1905, Albert Einstein assumed that time was like a river, ebbing and flowing depending on the effects of gravity and space, as time would accelerate and slow down around cosmic objects of different masses and velocities, so one second on Earth was not the same length of time everywhere in the universe .

It was ultimately Einstein’s theory that was not only believed to be the truth, but also proved to be completely accurate, as in October 1971, two physicists, named JC Havel And Richard Keating, validating it, and to do so, they fired four atomic clocks of cesium at planes around the world, east and west.

According to Einstein’s theory, when compared to Earth-based atomic clocks, in this case at the US Naval Observatory in Washington, DC, the airborne Havel and Keating clocks would be about 40 nanoseconds slower after their flight east, and about 275 nanoseconds faster after traveling west, due to the effects of Earth’s gravity on aircraft speed , according to their 1972 study in the journal Science.

The clocks already recorded a difference when traveling east and west around the world about 59 nanoseconds slower and 273 nanoseconds faster, respectively, compared to the US Naval Observatory.

This proved that Einstein was right, specifically with his theory of time dilation, and that time has indeed fluctuated throughout the universe, so there is a difference in time depending on each object and your specific location in the universe, it varies on the Earth itself, and outside the Earth.
