What is time? Can anyone give an example in which “time” does not mean some sort of change….? No one can.
Because time is the system we use to measure change. Time is to change what the metric system is to space.
Existence changes, and we measure that rate or pace of change using a method we call “time”.
Both change and time exist. But while change is physical, time is a an invented method to measure such physical change.
Some conflate change — a physical process that happens to anything that exists— with so called “time”, which is an invented method we use to measure the pace of such change.
Time is not the same thing as change. Time is to change what the metric system is to space.
Time is a method we humans have invented — and agreed to use — to rhythmically measure the pace of space´s change with discrete units in a way that is useful to us.
“According to the most accurate caesium atomic clock in the world, 1 second is equivalent to 9,192,631,770 cycles of the radiation produced by the transition between two levels of the caesium 133 atom.” https://www.sciencealert.com/physicists-have-broken-the...
Therefore, so called “arrow of time” is just a misnomer, in reality, what happens is that the way things change follows an order, this order or internal law is known as logos. Logos is the way changes unfold. It is not that “time only goes forward”, that´s meaningless.
Time does not go anywhere; time only is a measuring system we have created to measure the rate of change, and not a thing that moves, neither backward, nor forward, neither sideways… time is to change what the metric system is to space, something we use to get an idea of the relative change of something in regard to us.
Einstein wrote “the distinction between past, present and future is only a stubbornly persistent illusion”, meaning that only the everchanging present moment exist and anything you call past or future is part of the present and can exist only in the present; there is not difference between so called past, future and present because everything happens just in the present moment.
When you think about future, or the past, or as it is said “remember the past”, you are just using your brain in the present. All so called past and future are present activities, brain or otherwise.
Pictures videos and any other evidence is always presented in the present, therefore, it is never a evidence of past but just of present.
Technology and science works not because the future exists, but because the present moment is constantly changing in predictable manners, according to logos (aka laws of physics).
Bonus track: Zhuangzi’s Butterfly Dream
“Zhuangzi dreamed of being a butterfly
or the butterfly dreamed of being Zhuangzi.
All beings easily change one into another
everything is changing and change never ever ends.
The seawater at the distant Penglai
keeps returning clear to the shallowest stream.
The melon-grower outside the east gate
was once a wealthy Lord land owner.
Even rank and riches vanish
why so much fuss when everything is impermanent?”
