Do you not know how you synchronise two passing clocks at a joint instant in time within both inertial reference frames so that they show the same time afterwards ? All elementary books on SR tell you how. After synchronisation, the two clocks must keep on showing the same time since they are keepi...

[Johan: do you agree: (1) at each end frequency received is low first Wrong! then high for outbound and inbound journey. The received frequency at both ends is different for outward and inward journeys but the emitted frequencies stay exactly the same. (2) low, high frequencies are same the two end...

Therefore when time interval (delta)t passes within an inertial refrence frame K, the clock within an inertial reference frame Kp will show that exactly the same time interval has passed. If NOT then Einstein's first postulate must be wrong. How many times must I repeat this simple logic? Question:...

Excellent. We agree. Note that the LT has two components: gamma (time dilation) (1+ v/c) (Doppler effect). My argument applies: the received pulses from the outbound journey are lower frequency than from the inbound journey, but outbound and inbound is defined at the travelling twin end, and so ass...

Johan, again, could you please explain which two quantities the "time rate" you are talking about is a quotient of? Without an unambiguous definition any statement using it will not be unambiguous, either. Do you not know what time rate is? It is defined in terms of the periodic rate at which certa...

Now let us return to my argument above. You said it was wrong because Doppler did not apply to the pulse rate (frequency). You are lying again: I DID NOT SAY THAT DOPPLER DOES NOT APPLY. The Doppler effect is inherent within the Lorentz transformation and is thus included within the equations which...

A spaceship of length L within its own inertial refrence frame Kp moves with a speed v pass you (within your own inertial refrence frame K) and it switches on two lights, one in its nose and one in its tail, simultaneously. I have answered every one of your arguments, You have NOT! All you have don...

If they only use the data from when the aircraft are at altitude, how does the gravity change (other than the normal differences found on the planet from point to point)? You have to use ALL the data and changes that happenned at every second during the flights. It is well known that in order to sa...

Johan, I don't think you should try to correct anything till you have attended Walter Lewi's youtube lecture and corrected your misapprehension about Doppler shift! It did not help you out of your stupor: So why should I "attend" this lecture when I can deliver a better lecture on the Doppler effec...

Johan: Please refer back to my post above - I've explained in more detail why Lewi's lecture is relevant to your objection. You will remember you disagreed with my statement that received pulses would be lower pulse frequency due to doppler effect. I most certainly DID NOT. Why do you lie? I stated...

I did the calculation. The result is that the observers disagree on the amount of time which elapsed during the journey, which is consistent with the travelling person experiencing a shortening of the distance during travel. Then you have done the calculation incorrectly: Paste you calculation, whi...

http://en.wikipedia.org/wiki/Hafele%E2%80%93Keating_experiment It appears the experiment was done and not just done, but repeated with a precision within 1%. Experiments conducted: 1971, 1976, 1996, and more with increasing precision. The clocks were NOT flown through space without any change in gr...

. See above to Walter Lewi's MIT basic astronomy lecture on pulsars, where the pulsar motion relative to earth can be detected as a pulse frequency change. Of course you can do this but this has NOTHING to do with the twins paradox which we are discussing. Stop insulting MIT. You surprise me someti...

Perhaps your grandson aged 4 does not yet understand relativistic physics? Thank God for that. And thank God he did not learn it from your mentors. He is still sound of mind to think logically. And you are here making the mistake I highlighted above - assuming some frame-independent measure of inst...
