Smaller creatures experience time much faster than we do, so to them we seem to be moving in slow motion.
As we age, we perceive time faster because “adulthood is accompanied by fewer and fewer memorable events” (firsts), our biological clocks slows down along with a few other affecting factors.
A person’s perception of time tends to speed up with age.
Astronaut Scott Kelly will become even younger than his twin elder brother (also an astronaut) Mark Kelly (born 6 minutes before Scott), by three milliseconds after the completion of his one year mission on the ISS.
In 2008 there was a gamma ray burst, a violent cosmic explosion, 7.5 billion light years away, which is halfway across the visible universe, which could have been seen with a naked eye from the surface of the Earth. Anyone who saw it was looking billions of years into the past with their eyes.
In 1962, French explorer Michael Siffre spent two months in complete isolation buried in a cave below a glacier. His sense of time collapsed but his body continued to maintain a daily rhythm.
Time runs approximately 0.0000000014 percent slower on the ISS than on earth – after 6 months in the ISS, an astronaut will have aged 0.007 less than someone who had spent 6 months on earth, all due to time dilation.
When you look at a clock, and the second hand seems to freeze for a moment, your brain is actually generating a false memory, and your perception of time stretches slightly backward. This effect is called chronostasis.
According the quantum mechanical experiments, the future determines the present.
A day on Earth actually lasts 23 hours, 56 minutes and 4.1 seconds, not 24 hours as many believe.
