okay ill change my question: everyone knows about those atomic clocks who were synchronized with one flew in ultrasonic plane and the other on earth. When they analysed the results the clock on the plane was running slow..However from pilot's point of view, the earth is moving at that speed. So he would anticipate that the clock on earth to be slower but he is wrong. FUCKING WHY

I thought neither would be wrong? All frames of reference are accounted for and so they are both valid..

r u tryin to say there's gonna be no difference in time? after the experiment the clock on earth was running faster which was one of the proofs that proved einstein's theory of relativity

No i'm not saying that. From the frame of reference on Earth, the difference on time between the Earth and the plane is evident by Einstein's theory of special relativity stating that the moving clock will tick slower.

However, from the frame of reference on the plane, moving at a constant speed, you could say the Earth is in relative motion to the plane, causing the clocks on Earth to tick slower.

Hence from both of the frame of references, they are both valid.

EDIT: Sorry, "accounted for" was bad wording. What i meant was no frame of reference is favoured over another.

Basically it's because there is acceleration in the case of the the plane going around the earth that clocks show different times.

if they are both valid, then why only one of them is correct at the end when the plane landed?

 

[IamBread]

You need to remember that in special relativity there is no acceleration, and thus no changing of reference frames. If they continue in their own separate FOR then both are valid for each others FOR. Once one of the objects accelerates, it changes it's FOR and SR doesn't hold.

Because the plane changed it's FOR and underwent an acceleration.

 

[viraj30]

whats FOR

 

[IamBread]

Frame of reference

 

[nightweaver066]

whats FOR

Frame of reference.

ok i think im starting to understand it +rep to iambread
