What tells the time to run slowly 4 one who is moving faster with respect to the observer?

Question

i think that there should b a law that governs all this phenomenon i.e a law which tells the time to run slowly and which selects the speed of light to b a limit and not any other speed?

Answer 1

Nothing "tells" time to run slowly.  The fact is that time is not invariant; it looks different to observers moving relative to each other.  Only the speed of light looks the same to everyone (in conditions described by Special Relativity... black holes need not apply).

Since the speed of light looks the same to everyone, you could use a pulse of light bouncing between two perfect mirrors a given distance apart as a clock.  Those clocks would tick at the same rate for everyone who brought them together to compare.  But if someone went past you at high speed carrying their clock, you'd see their pulse of light moving diagonally rather than directly back and forth.  If they were moving at 0.8 the speed of light, you would see the pulse travelling the hypotenuse of a 3-4-5 triangle.  The portion of the pulse's motion between the mirrors would only be 0.6 c, so the clock would look TO YOU as if it was ticking at just 60% of full speed.

But that's just how it looks to you.  To the traveller speeding by with the light-pulse clock, YOUR light-pulse clock would look slow!

This sounds like a contradiction, but it's not; as long as you just fly past each other, both clocks can be "slow" to the other observer.  To settle the issue of whose clock is right, one or both of you would have to change speed (a LOT of speed) and meet up again.  That change in speed also changes your clock.  The one who changes speed the most will have the clock everyone will see as slowest.  That's the source of the "twin paradox".

Yes, this sounds nonsensical.  That's because we are only familiar with things which move far too slowly for relativistic effects to be visible.  The same is true of quantum mechanics; we can't directly see or feel anything small enough to show quantum effects, so the laws of QM sound like something out of a fantasy novel.  But if they were fantasy, we wouldn't be able to use them to predict our observations so well.

Just goes to show, the universe is not just stranger than we imagine, the universe is stranger than we CAN imagine.

Answer 2

First of all, your opinion doesn't count. The universe runs the way it does.
Time does what it does so that the speed of light can stay a constant. If you're going near the speed of light, and you turn on a flashlight shining forward, that light has to go the speed of light too. But it can't go faster than the speed of light. How can that be? The answer is, it still can, if you simply caculate
s = (v)(t). Use "c" for "v". If you can make the time be small, the calculation still works. And that's how it works. "c", the speed of light, stays the same, and it does it by time dilating. When you finally figure that out.....it is SO COOL. "c" is THE ONLY TRUE constant. Constantly constant.

Answer 3

Einstein's relativity equations, like Newton's laws, provide the laws governing relativity. Nothing "tells" time to run slowly relative to an inert reference frame. It's a logical conclusion. That conclusion comes from the yet-to-be-disproven discovery that the speed of light is constant. That means that if something is zipping past you near lightspeed, light from it to your eyes will take a longer path, from your point of view, than if it were standing still, from your point of view. Since the speed of light is constant, what has to give in the formula Distance=Rate x Time is Time. Light will have to travel a longer distance but at the same fixed speed. As far as the object zipping past you is concerned, it's standing still and YOU are the one that's moving. It's a long discussion, but for every second that passes on the object's clock, you will measure a longer time. For every second on your clock, the object zipping past you will measure a longer time. It's a paradox but, like I said, it has yet to be disproven. In fact, evidence that this is true is shown when you accelerate a muon (an subatomic particle) to near light speed. Normally, "at rest," muons exist a few billionths of a second before they decay into other particles. If you accelerate these muons, they acutally live longer. Again, this is by your clock. As far as the muon is concerned, after a few billionths of a second, it's still doom time. Hope this hasn't confused you more. There's a lot of stuff to learn, if you're interested.

Answer 4

I dont think time runs slowly for one person and not the other.

My theory is that if youi are moving close to the speed of light or at the speed of light, you become light and you are moving so fast you can get more done in the same amount of time. Time slowing down is a theory.

Answer 5

As a self-taught drummer myself, i visit inform you that there somewhat is not any 'quick" thanks to study an device. It takes a great number of endurance, practice, self-discipline, and exertions. Now that being pronounced, some human beings do study faster than others so it truly relies upon on the man. I truly have 2 cousins that both play guitar and both are self-taught. My one cousin Terry practiced noticeably a lot each day and picked it up faster than my cousin Dave, who did not practice almost as a lot. Terry grew to change into noticeably darn strong in about 8 months. all of it boils all the way down to how determined you're, how a lot you practice, and how straight away you %. issues up. My suggestion will be to get an tutorial e book or DVD and study some chords. in case you do it on your man or woman you'll save a great number of money and also you could flow at your man or woman %.. Guitar instructions aren't any more less costly at present, until eventually you comprehend someone. merely provide it a shot on your man or woman for a month or 2 and be conscious the way you progression. Then in case you sense you want instructions to get better, then stumble on a strong instructor which could no longer too extreme priced. besides the undeniable fact that the merely right prognosis is to coach....practice.....practice! strong success!

Answer 6

If you're moving fast relative to me, we both still measure the speed of a light signal, relative to us as the same. This is an experimentally verified fact. Back in the 1890s the Michelson-Morley experiment was the first experimental verification, but there have been several different experiments to confirm it since then. The only way to explain this without any logical contradictions is for me to say that time is running more slowly for you than for me, and for you to say that time is running more slowly for me than for you.

Answer 7

i agree < time runs slowly in accordination to where we live example (earth 24 hours a day ............jupiter something like 3000 hours per day) time all depends on where your sitting its not like universal( nobody tells time to run slowly thats just a way the scientists found to count days that pass for calanderizing time for history purposes and not losing track of what we do....(for an alien if they exist there might not be time where they are)once the speed of light has been recognized as a fact amungst scientists then i have a feeling that there will be laws that govern time .....untill then everybody will probably act stupid for not knowing any better>>>ps one scientist has a theory and ten other scientists slap him in the head .....i mean in order to get better as humans we should work together instead of everybody just having a opinion and fighting about it ,we get nowhere fast.

Answer 8

what tells the water to run downhill in a gravity gradient?

it is the complex laws of gravitation which nobody fully understands, and yet we can see the effects easily


the laws of relativity are also complex but can be observed

highly accurage clocks that are moving at very high speeds relative to one another (such as a clock on a satellite) develop measureable dis-parity

there are several good books on general and special relativity written for the lay-man

Einstein even wrote one (in German)

I don't understand it, but you ought to give it a try

Answer 9

In space, I think, they did this experiment, where the astronaut, had to stay busy doing things for 8 hours, without having a watch. At the end of a period during those 8 hours, he always thought it was earlier than it actually was. To that, I think you will find that time is relative to whatever is going on, and regardless of who is involved, observer or action, time is relative, and constant for everything.

Answer 10

time does slow down the faster we go, and the real reason for that (like some people have already stated) is that the speed of light MUST remain constant. therefore, time slows down in your perspective *just enough* so that the speed of light still keeps its 186,000 miles / sec speed. how does this work then?

relativity really is a long discussion, so i'll just illustrate with an example. :p

suppose you managed to speed up to 185,999 miles/sec, just 1 mile/sec short of the speed of light. technically, light would just gain a mile on you every second then. but according to relativity, time slows when you go faster, and light has to retain its 186,000 miles/sec speed. but to keep this speed, a second has to be 186,000 times longer (because light gains 1 mile per second, and if one second was 186,000 times as long, then light would gain 186,000 miles per "second"). and lo and behold, this is EXACTLY what happens.

at a speed of 185,999 miles / sec, time for you is 186,000 times longer - just enough for light to keep its speed.

note that this is also the reason why you GO FORWARD in time when you speed up - at 185,999 miles/sec, time for you is 186,000 times longer, and time OUTSIDE YOUR PERSPECTIVE (which is everybody and everything else) is 186,000 times FASTER. at this speed, for every second that passes for you, a little more than two days pass for everyone else.
