Einstein’s Special Theory of Relativity time dilation is a difference of elapsed time between two events as measured by observers either moving relative to each other or differently situated from a gravitational mass or masses. Time dilation explains why two working clocks will report different times after different accelerations. For example astronauts return from missions having aged slightly less then, had they remained on earth.
Also the comparison of muon lifetimes at different speeds is interesting. In the laboratory, slow muons are produced; and in the atmosphere, very fast moving muons are introduced by cosmic rays. The cosmic ray produced muon traveling at 98% of the speed of light is about five times longer, in agreement with observations.
So speed acceleration slows down time run and vise a versa, for time acceleration speed must be reduced.
Lack of time is a problem, about which the majority of earth’s society is very concerned. Many scientists claim that time started to run faster on earth, and people notice it, because it has changed radically. This may be caused by the climate system changes, including changes in atmospheric composition (e.g., increased concentrations of greenhouse gases), industrial era, solar luminosity, volcanic eruptions, and variations in Earth's orbit around the Sun. As a result, our planet changes the orbit towards the sun, getting more closer. The closer a planet is to the Sun, the slower it will spin around it. With the decrease of the speed, the time run is to be accelerated. And it is today’s reality.
One needs too much effort too feel and realise every moment of life. Reality seems more to be a psychedelic movement, frozen in a mass hallucination
