What is realtivity of time?

Question

What is realtivity of time?

Answer 1

time is all relative to where you are in the universe and the circumstances of gravity

Answer 2

Humans define time as a physical quantity.It is measurable to an accuracy depending on the instrument used.Realitivity of time or matter got it`s genesis from speed, the speed of light.From as early as the nineteenth century,many mathematician and theoretical physicists,made models ,calculations and observations in cyclotrons and other subatomic particles laboratories to isolate and obtain a singular *free* quantity called Time ,with no success.

Since velocity and/or speed is dependent on time,then anyone of the two quantities provided the genesis and a starting point.If the speed of light is the ultimate speed achievable in our (slow) universe,they wondered what would happen to matter tending to or approaching the speed of light.Some philophers *** physicists *** mathenaticians agree and have formulated equations to show that matter would undergo some transformation,but what about time that is associated with this *high speeding matter*?

So far, every observer finds that clocks in motion ticks slower relative to him than when they are at rest.

Considering Meson decay, it was shown that different observers in different time frames would measure a given time interval differently but the time interval would not change, say t1-t0

In one case an observer would need a clock,in another frame of refrence an observer may need a clock and a yardstick to measure the same time interval We cannot travel back in time nor in to the future.If we happen to do, we would have to formulate new theories of electromagnetic radiation and discover a duality in/of energy as we know it! It would seem ,therefore, that space and time is inextricable tied up.Let us brain storm a little.If I define my universe as never contained or has no end and  boundryless and I am in the middle or some where, where there is no visible or measureable object or entity at all. (forever?) And assuming I am in ship travelling at any speed,how far would I go in let`s say a trillion Earth Years? My answer is nowhere.I shall still be in the same spot,you understand?

This is as simple as I could make it in one little chapter without quoting  or using The Lorentz Fitzgerald transformations or other formulae and Concepts in modern physicsThere is much more you can read from magazines viz. The Observer,Nature,Scientific American or search the Web or just meditate!!(funny)

Answer 3

In scientific language: time is relative to an inertial frame of reference.

In common language: if someone was to fly away from the earth and back at very high speed (close to speed of light) their time would run slower than time on earth. At the speed of light, the time would stops completely.

It's also suggested that in proximity to massive objects, time also run slower. Gravity affects not only space but also time.

Answer 4

If you and your twin brother each have $100 in your wallets and synchronized clocks and part ways and meet later, then

* each of you still has exactly same amount of money: $100

* clock of you and your twin brother show different times

Morale of this parable:

money is absolute, time is relative.

Answer 5

Relativity simply means order...whether it is from numbers like dates...or sequenced events like history.

Relativity in science is about juxtaposition and understanding.

Answer 6

Basically, the postulate Einstein brought up was that time is relative.

Let's say you're standing on the ground.

Let's say Einstein is on a moving train in all his frizzy-haired glory.

Now both of you have 'ticker-tockers'- basically like a paddle-ball sort-of time-measuring device. Each of you will think that your ticker-tocker is measuring time correctly.

The thing is though, the paddle-ball for you is covering a distance 2d (let's call it that for now)- where d is the distance from the paddle to its maxima.

Mr. Einstein's paddle-ball is not only covering a distance 2d in your eyes, but whatever horizontal distance he has moved in that time span (since his train is moving).

But the paddleball/ticker-tocker/thingamajig or whatever you want to call it is going at a constant velocity- that was established at the very beginning- that's why it's used to measure time- for the sake of having a standard.

So, something's up here, isn't it? this ticker-tocker has a constant velocity, you're ball is going a certain distance, Einstein's ball is going a greater distance, but, and here's the catch, you're measuring the same time span.

BLOODY h**l!

The velocities are the same, and v = d/t, t = d/v.

So according to you, Einstein's time reading is larger than what it should be, so Einstein's ticker-tocker is slow (because distance is in the numerator, and it's greater than what you think it should be).

Similarly, Einstein thinks your ticker-tocker is slow (because it's as if you're moving backward for him, and he's stationary, right?).

This concept that time is 'relative' is an important concept of relativity, and it is referred to as 'time dilation.'

If you think of the paddleball of the 'ticker-tocker' as a photon of light, and the paddle as a torch, you would have just read/imagined Einstein's own thought-experiment when he thought of this.

...and that's why he's got frizzy hair. =]

Ciao.

Answer 7

time is relative to the observer, try these you tube vids for an explanation...
