Love all of it, especially mentions of the Dead Sea and this:
It (time) shouldn’t be an arrow.
(Dean Rickles, philosopher of science at the University of Sydney, Australia)
Despite Einstein’s theory of relativity proving otherwise, society still for the most part believes time is as simple as a storybook with a neat linear storyline. Don’t let your evolving human senses fool you. Here are some points to help you reconsider that thought.
Russian astronaut Sergei Krikalev has spent longer in space than anyone else - 803 days in total. While space’s weaker gravity aged him, this was outweighed by the rejuvenating effect of his high speed. So he is 21 milliseconds younger than if he had stayed put.
Repeat a famous experiment carried out with atomic clocks and you will age 40 nanoseconds less if you circle the globe eastward, in the direction of Earth’s rotation. Fly west, though, and you will age 273 nanoseconds extra (Science, vol 177, p 166).
Your Head Ages More Than Your Feet
…by around 10-11 seconds a day. Live for 80 years and that difference adds up to 300 nanoseconds.
Location, Location, Location
A year atop Australia’s tallest apartment block will make you 950 nanoseconds older than a bungalow-dweller.
The Youthful Dead Sea
Spend 40 years by the shores of the Dead Sea, at the lowest elevations on the Earth’s surface, and you’ll age 48 microseconds less than someone living at sea level, and 750 microseconds less than the residents of La Rinconada in Peru, at an altitude of 5100.metres.
Had time truly been a constant, a linear variable of the universe it would apply itself equally and sequentially throughout our lives. But as we look closer, it clearly looks like that is far from the reality of things.
“The truly odd thing is that the laws of physics, which surely ought to be responsible for what we see in the world, can work just as well both forwards and backwards in time,” says Dean Rickles, a philosopher of science at the University of Sydney in New South Wales, Australia. “There shouldn’t be an arrow.”
If time’s arrow is not in the laws of physics, where does it come from? An important clue emerges from the complex interactions of large numbers of particles. Every object you see around you, including you, is made up of a vast collection of particles. These particles are not just sitting around - they are constantly shuffling about and rearranging.
