can you tell me how is this possible that when you reach the speed close to speed of light time slows down?

Question

i know that Einstein's special relativity proves that but how?why by reaching high speeds time slows down?

Answer 1

Unfortunately, a really accurate description of the reason that time slows down at speeds close to that of light is beyond the scope of this forum. However, perhaps the following (very brief) account will suffice, with links to sites that may help much more.

As an object's velocity's object approaches very close to the speed of light, that object's rate of time will slow down as observed by others moving slower in relation to the fast object. This effect is called time dilation. The effect occurs even at slower speeds, but it is not normally noticeable on earth in everyday experience. If we and objects around us moved constantly at 99% of the speed of light, we would have a radically different view of the world, and thinking in relativistic terms would be normal. Our problem is that relativistic effects (such as time dilation) seem counterintuitive and out of synch with our earth-bound existence.

The shortest and simplest explanation (and not a very good or complete one) is that time dilation is a direct consequence of the deep interconnectnedness of space and time (which is why Einstein called it "spacetime"), and the equivalence of mass and energy (or mass-energy), and the fact that the relation between an object's speed and rate of time are related to the speed of light. For any moving object, "NOW depends on how fast you're moving." (See first link below) An earlier answerer said that it has to do with geometry, and in a sense that's right. It has to do with the geometry of space-time and the strong constraints that space-time geometry place on an object's velocity in relation to other observers and the speed of light.

By the way, time dilation is real and measureable in the real world, with important consequences to time-keeping, global positioning measurements, and other areas... read:

Answer 2

at the start we could understand that our theory of time will constantly be the comparable, a minute will constantly "sense" like a minute even nevertheless our velocity is on the fringe of the fee of light.we can't sense that we live longer if we pass speedier. what is going to substitute, is how the observers are perceiving us. in the event that they might watch us vacationing at very extreme speeds, our strikes will decelerate further and extra the closer we get to the fee of light. If we could pass decrease back and learn our clocks, there'll be a important distinction in them. The time slows down for the observer that has been below acceleration forces, no longer the only that has stay in an inertial reference. Time additionally slows down below gravitational fields. We could understand that gravitational forces are the comparable as acceleration forces. All this that sounds so strange, is defined in an ordinary way in many books approximately relativity.

Answer 3

Let's say that you could see the face of a clock on a planet that is exactly 1 light year away. your seeing the time on that clock as it was a year ago because it took exactly one year for the light off the clocks face to reach you at the speed of light, now say you had a space ship that could travel the speed of light and you raced toward that clock on the other planet. while still looking at the clock on your way there, as you approach the speed of light the hands on the clock would move faster until you reach the speed of light and the clock would move twice as fast. Now, move away from the same clock at the speed of light and you'll notice that the hands on the clock has stopped. Note....In either direction, the clock hands are moving twice as fast or not at all. Time does not slow down or speed up. It's all relative. NOTE: We cannot talk about time as if it were something tangible. Movement through space or on this planet or anywhere else for this matter cannot and will not slow time down or speed it up. There is no (tangible) nob on time that we can adjust. Time is an idea. On the other hand moving through space at the speed of light or at any speed IS something that is tangible. Put it another way: you cannot change something that is non tangible with something that is tangible! There is a web site here that explains "Doppler Shift" which has to do with sound waves and light waves.

Answer 4

Nothing to do with time being "imaginary quantity" (which by the way it is not - it just behaves kinda like one in the most simple - flat - case), and nothing to do with the delay with which you see somebody's clock either (what Teratura explains is Doppler's shift - nothing to do with time dilation).

it is simply a geometric effect. If two cars travel at an angle to each other, it would look to the driver of each car, that the other car is going slower (falling behind) then his own.
Same thing with time. We are all "moving" along the axis of time (with the speed of light actually) all the time. If both you and I are at rest with respect to each other, our time axis are parralel, but if you start moving in space, your time axes turns a little (the faster you move, the more it turns), and becomes at angle to mine, so, exactly as in the example with moving cars, it will look to you that I am moving (along the time axis) slower then you, while I will think, that it is you, whose time slows down.

Answer 5

hello butterfly , i will try to answer this by rulles of prophesor Hoking and einstein vew from the spaciel relativity.

you see... you you need to be in someplace at 5:30
and now the hour is 5:00

if you move in some speed you will ge there at 5:30 (T=30)
if you will get twice faster , you will get there at 5:15 (T=15)

if you move very very fast , you might get there at 5:00:01

if you move the speed of light.... you will get tehre at 5:00 (Limit T = 0)

in other words
you could look back and see you're self still stending .

if you move faster then speed of light , you will Theoreticly get there at 4:59 (T = -1) :) mathematicly posible

Phisicly not...

Answer 6

Time does not slow down for you if you are the one moving; those around you who are not moving would say that your time is slowing down.

Answer 7

there is a lot of math that i don't get, but time is different depending on velocity since velocity is a real quantity and time is an "imaginary quanitity".

Imaginary in the sense that
(time) * (time) gives a negative number.

yahoo search the following three terms "cuny time dialation"
and you will get a good site from City University New York by a person named Hunter. I don't quite have the math for it.

Answer 8

Speed of light is greater than time.
If you car is going at 90 m/h and another car at 60m/h can you say the time of the car going at 60m/h has slowed down.

Answer 9

It would just be the perception of time, not actual time.
