If you speed up, time slows down. This is true for atomic nuclei, clocks, and human life.
The mechanism that makes a clock tick, for example, will slow down when it is placed inside an airplane moving at 300 mph. It will actually slow down
imperceptibly if you accelerate it to even 1 mph, or 1/2 mph. But you can actually measure the change in atomic clocks using jet planes.
The first way they confirmed this phenomena (afaik) is with atomic nuclei decay. The decay rate of atoms traveling at 99.9% the speed of light were
drastically slower than those not traveling at all. This is because time slows down (for everything) when it moves faster.
Read relativity. Einstein is a cliche for a reason.
(A foreword, I'm not exactly that educated in relativity, Anything I say is my own conclusion and/or confusion)
I understand the concept you present. But to me that's just existance. You use a key word when you say, "But you can actually measure the change in
atomic clocks using jet planes.". That word is measure. If humanity and other forms of life aren't here to measure that with seconds, miliseconds,
etc. Then isn't it just existing without measure?
And hence wouldn't that mean that time is of human nature? I have a hard time being convienced that time exists without someone to measure it. Do
things still happen? Yes. Do event's still take place that shape the present? Yes. There's no denying that much, But that's just the ever changing
present.
See in my opinion if no one records history or no one is here to "discover" remenants of history, Then it's just as good as it never happening, Of
course WE know it did, Because we have cognitive brains, And can remember, But a tree or a fly doesn't know what happened two hundred years ago. And
I believe there's a good reason for that.
There's no need to have a past, Or to remember it for that matter. And I'm sure along the way someone will bring up evolution. (I.e- If there's no
need for a past why do we evolve in effort to "out live" the things that killed our species before( I.e-Survival of the fittest)) And To that I'd
have to say that evolution is simply the passing foward of genetic material more suited for the dangers of the present.
Anyway's back to the topic. I have an interesting theory, That will never be able to be put to test. But I feel like it would answer alot of
questions being presented in this thread. The theory is that if a child is never subjected to a measure of time, would they still feel the need to
have one. You could do multiple experiments, Such as:
1)A new born child is raised in a captivity setting, Where there is no such things as a clock or any measure of time. Raised in a secure room, Where
they cannot see the sun, and any food or other object is brought at complete random intervals through out the day. Then upon reaching the age of ten
(of which the child wouldn't know their age), Being asked questions about the past and the length of time passed.
-I think the result would be rather obvious, In that the child would not be able to do so. Clearly because they were never TAUGHT anything of the
matter.
So what am I getting at? I think time is only relative to a measurement. If we can't measure time with a sundial or a clock or night and day, It has
no meaning. And if something has no meaning, It has only existance, Or the present.
(I apologize if that starts to not make sense, I ramble from time to time)
