Not directly but the "operator" of the clock could add that info ,could he or she not? (and thus synchronize the two clocks) Not sure what your "what post did I reply to?" is getting at.... but no I don't think you replied to any of my posts in this thread. I did "cut across" your conversation with Taingorz though. Link to comment Share on other sites More sharing options...

We can explain what a second is to you. If you are holding in your hand, while managing not to shake it very much, a caesium 133 atom which you observe being in its ground state, and you count 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of this ground state, then you have just experienced one second of time passed. Moreover, anybody or anything that stayed fixed in space with respect to you during the entire counting process has experienced exactly one second as well. Now just as you can measure the distance between different things using a meter stick, you can measure the time passed between different events using this device, which is commonly called a "clock".

Taingorz Posted August 4, 2018 Share Posted August 4, 2018 'Science' never really understood anything at all. 'science' was designed to be a control tool, once the religions didn't work as well as they once did. 'science' has nothing to do with finding any 'truth'. 26 minutes ago, taeto said: blockquote widget An obvious reason might be: when I show you a definition that is not circular, you immediately complain that it is circular.

I see it as a reasonable answer. What I find as particularly illogical and showing signs of an agenda is the following.... Quote well space time really can't exist but I will leave that for now, And experiments agree? That remains to be seen then.Because it is never about the experiments but about the interpretation of the experiments of course. Just a little logical thinking can show space can not curve. You don't need higher math or experiments. "Spacetime really exists and has been shown to exist with many observations including the Lense Thirring effect, gravitational lensing, and in more recent times gravitational waves. The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality".

Hermann Minkowski: With all due respect, but you are not saying anything here. You are just saying there has been done things that proof it. Bit nothing concrete at all. And e.g. gravitational lensing can be very easily explained by classical physics. Link to comment Share on other sites More sharing options...

Science seeks explanations of what we observe through observations and experiments. It's wrong to say that it has nothing to do with finding truth, rather seeking truth per se, is not its objective, if this truth or reality actually even exists. Science is based on empirical evidence: Religion is based on faith. Understand? One would then ask why you use and depend on science every single day of your life if it is based on not understanding. I mean saying that is not just circular, it is inane and obtuse to boot. You my friend would still be swinging in the trees if it wasn't for science and the scientific methodology.
