Mmm...I am not a smart boy, but I think we cannot measure time.?

Question

For me, time is flexible and we cannot measure it.
Time has own density. Clock is only a scale and not to measuring time.
What i mean by time is only a scale is example my self.
I born on23 july 1988. On 1 january 2007, l still 18 years old but l force as 19 year old.
Im a dyslexia, and my teacher is not agree with me. Example above not a tough example to ezplain my opinion and l really not know how to explain it.
Please.

Answer 1

You say you aren't smart, but anyone who thinks about the true nature of time definitely has a respectful amount of intelligence.

You posit that we cannot measure time. But almost every scientist conducts most every experiment based on a measurable time scale. Whether a pendulum moving back and forth in ancient clock, a capacitor discharge in an integrated circuit in a digital watch, or the transitions of electrons in cesium atoms in an atomic clock, time has been shown to be constant (in non-relativistic systems) every time we measure it.

Think about what you've suggested. If we could not measure time accurately, then sometimes days would be 25 hours long, and sometimes 23. Sometimes we would circle the sun in 360 or 370 days.

Time may seem to sometimes speed by (that happens to me when I'm having fun) and sometimes drag (like when I'm bored). But if I check my watch against any other time reference system, I find that my time progresses at exactly the same pace as any other system.

Einstein proved mathematically, and scientists have proven experiementally, that time can vary if you are in a moving reference system. But that only happens in a meaningful way as that motion approaches the speed of light. In our fastest space ships that relativistic time shift only changes things by a few millionths of a second. So relativity-based time changes are not what you describe.

But it is good that you are thinking about how time reference frames might change. I hope you continue to think like this, and study physics. Perhaps you will discover a whole new way to think about time. Good luck!

Answer 2

We can measure time but you are correct, Time is flexible.

A scientist about 100 years ago said the same thing.
He said that time was not always the same for everyone.

Originally nobody believed him but he proved them correct with math.

Lets say you are in an imaginary starship travelling as fast as a beam of light, which is very very fast.

And you have a friend who is staying home on Earth.

If you go away for a week and then come back.
Only seven days will have passed for you - (it was only a week long trip after all).

But your friend will have gotten many weeks older, that's because you were going so fast , that time slowed down for you.

How much older depends on how fast you went and for how long.

But you wouldn't notice it. Everything would seem normal on the spaceship your clock would seem like it was working just like normal.

But to your friend on Earth, you would seem to be moving very slowly but really you're moving very very fast.

The person who discovered that idea was Mr. Albert Enstein and the year was 1905.

Unfortunately however, you probably haven't left the Earth on any very fast spaceships so as of today you are 18 years, 4 months, 17 days old, in a couple of weeks you will still be about 18 years and 5 months old.

Try not to grow up too fast though, there is an old saying

"It's not your age that matter, it's the miles you travel."

Answer 3

Seems to be a bit of confusion here about what you actually mean by "time".

Clearly, our everyday experience of time can be measured. If I ask you to meet me somewhere next Tuesday at 4pm, we'll both be there at the same "time". If we couldn't measure it, things would be a bit chaotic, wouldn't they. We'd never manage to meet up.

But if you mean time, as in our fourth dimension - the time that is inextricably bound up with space to form space-time - that's very different. That is indeed flexible and can be warped (gravity is an effect of the warping of space-time), it may even be able to loop back on itself, slow down etc.

I have no idea whether that kind of time can be measured, or even how. I think only the really clever people can tell us that.

Answer 4

I agree with you. Our measurement of 'time' is merely a convenience. I believe that time does not really exist - only degeneration takes place. Different things degenerate at different speeds. A tree lives for what seems like hundreds of years - a fruit fly lives a whole lifetime in what we measure as one day. In my humble opinion....

Answer 5

Time is defined so that motion looks simple.

An object moving in space with no forces on it will move equal distances in equal time. Equal distances can be determined by using the same ruler, over and over again. The object moving without forces will take the same time to move the length of the ruler.

Answer 6

Time DOES exist and can be measured but as you said it is flexible.

Time is a requirement of everything around us. People confuse our measurement of it with defining it.

Our measurement is useful, hours minutes and seconds help our lives run smoother, and again we didnt design this we took it from the movement of our planet around the sun.

Think of a tree, without time the chemical reactions would not take place.

Time is all around, you are simply confusing it with the time system that our lives run on.

Answer 7

Absolute gibberish.

Don't know why you dont think clocks can measure time. Maybe yours just needs new batteries.

Regards from the planet earth.

Answer 8

Time is relative to speed.
IE special relativity.
For instance, if I were to devour a Peach 'n' Berry pie at a rate approaching the speed of light, time would go slower for me, so that people observing me would see that I am aging more slowly, and my body will also contract, however fat I am becoming. Strangely, I will also see the people around me contract, as speed is also relative.
Holy cow.
I think I should go back to my pie and forget you ever asked this question.

Answer 9

For all practical purposes you can measure time very accurately using clocks.

Answer 10

Clock time is a purely human construct. But Entropy is a fact of death.
