Speed of light?

Question

I came to know that if we travel at the speed of light than time stops. So if the light travels at it's speed then time should stop for it.

Answer 1

It is not true that time stops for the light; the light "experiences" time the same as if it were "stopped". That is an essential part of the theory of relativity--there is no way to detect uniform motion at constant velocity (without reference to something "outside"). What stops is OUR observation of time on the light beam--if we could see a clock on the beam, it would appear to US as if it stopped, but it looks "normal" to the light beam.

This is all fantasy, however, since there is no way for a clock to be on a light beam, nor is there a way for us to observe it.

However, the same holds for things moving near the speed of light. Our observation of the clock shows it is slow (not stopped), but a person travelling along with the clock would see it keep regular time.

Answer 2

good sufficient. Time does now no longer circulate slower for speedy gadgets. evidently to you, assuming you ought to be table sure, that ingredient is passing slower for speedy gadgets. If there are not any accelerations reward - each thing is often shifting on the equivalent speeds relative to a minimum of one yet another - then there is not any thank you to tell who's moving and who's at rest. Now the twin paradox, which you style of paraphrased here, has 3 accelerations in it. you start up from entertainment and attain an incredibly extreme velocity. After a time, you change around this potential which you slow down, you momentarily cease, and additionally you velocity as much as a extreme velocity back. hence you attain earth and slow to a stop. At each and each acceleration, you adventure acontinual which the earthbound guy or woman would not so it is clean who's in flow and who's at rest. as a result, you are going to return after 10 years it slow maximum powerful to hunt for out that a lots longer time has surpassed on the planet. Now famous person trek assumes there is the thank you to adventure exterior of the 4 dimensional area that defines the universe - the so-time-honored as subspace. in this subspace, relativity would not stick to - it is exterior the universe exceptionally lots - so which you ought to circulate from ingredient to ingredient in a finite quantity of time and, the time it takes to traverse the hollow as measured via the starship's clock could be the time that elapses interior the universe - style of no longer likely although crucial while you're writting one hour long television episodes. there is not any data for the kind of holiday use in sought after guy or woman trek.

Answer 3

That would be relevant to the light or the visual perception of the person traveling at the speed of light.

That is why it's called the theory of relativity.

Answer 4

Yes, light experiences no "time". That is why it can travel for millions of years without deteriorating.

Answer 5

That is true. A photon doesn't experience time. From the production to the annihilation, everything happens in a single moment for the photon. Not for us who observe the photon, of course.

Answer 6

no, time wont stop ever," if you put a little baby on a space- ship and sent that spaceship one light year away,that little baby would be an old man by the time that ship traveled one light year!!

Answer 7

Absolutely...

Answer 8

Time doesnt stop, it slows.

Answer 9

HMmMmmMMm

Answer 10

you are wrong. time never stops, not for anything
