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...

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. I did the calculation. The result is that the observers disagree on the amount of time which e...

Johan, you continue to talk about a "time rate". As you are surely aware, a "rate" is a quotient of two quantities. Could you explain which two quantities you mean? Wrong again. Do the full calculation. On the outwards journey the two light sources move away from one another and the light will be re...

If these two statements are true: 1) The relativistic doppler shift of electromagnetic waves is an actual, observable phenomenon. 2) The SI definition of a second – being the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the gr...

Just to be clear: in a world were there are no copyright protections, there is no music, no movies, no games, no creation outside the sciences. A lot of content is created where the creator either does not care or even actively encourages free sharing, and at least my perception is that the amount ...

Let me ask a simple question. If you have two inertial reference frames Kp and K, moving with a speed v relative to one another and within each reference frame there is a meter-stick at rest: Do these two meter-sticks have the SAME lengh within their respective reference frames Kp and K? Yes they h...

It is not circular at all. This is only one possible experiment: If you get the same result within two inertial reference frames for any experiment (as you will), it proves that the laws of physics are the same within the two inertial reference frames, which in turn DEMANDS that any apparatus you u...

But any observer can only ever be in one FOR, and to infer what is going on in other frames he needs to use the Lorentz transformation, No he does not: Marconi already invented the radio more than 100 years ago. After the two observers have measured the decay rates of the same substance within thei...

Within their own respective inertial reference frames they have exactly the same time axis. Only when you look from one inertial reference frame into the other does the Lorentz transformation apply, and only then do they have different time axes: And this is a symmetrical view. No one is arguing th...

Two different inertial reference frames have different space and time axes. No they do not! they have exactly the same time axis. Clocks at all popsitions within an inertial reference frame keep time at the same rate and does NOT change frrom one position to the next. I wrote two intertial referenc...

What is time? A second is defined as "the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom". Thus it is a sequence of oscillations of electromagnetic radiation . Both points are very import...

SR mandates no such thing. Wrong! See post 599. Unfortunately this forum software does not feature post numbers (not post counts), so I don't know which post you are referring to. It's certainly not on page 40. I'll try to write an explanation of why I believe SR is compatible with the things you s...

Johan, Demons are fine, since you can take any reference frame and simply declare it to be the "global reference frame" (even though it is not observed to be special in any way). However if we do that and e.g. assume K to be this reference frame, I do not believe your thought experiment turns out th...

To add some more, the concept of "measuring c", while seemingly intuitive, is deeply flawed. It's circular: How do you measure c? - By measuring the time it takes for light to travel a certain distance in vacuum. How do you measure time? - With a clock local to the observer. How does a clock operate...

Johan, I'm very much looking forward to your argument, though I will be quite busy over the next few days. In the meantime, I read your draft "On Einstein's Non-Simultaneity, Lenght-Contraction and Time-Dilation". Unfortunately I believe it contains some crucial mistakes. The time inverval as seen f...
