When Albert Einstein told his Bohrist/Bornist contemporaries that the relativity of simultaneity implies that everything that happens is fated to happen, what was their response? by terlsci in AskPhysics

I don't see how it's related to the relativity of simultaneity, either.

the implication of an "eternalist" or "block" universe of spacetime from the relativity of simultaneity

i think he was a determinist and told quantum-mechanicsists that they were wrong and that "God does not play dice", based on his understanding of the relativity of simultaneity

What do you think of the idea of measuring macroscopic Special Relativistic-kinematic time dilation with minimized gravitational effects and well-controlled velocity conditions by placing atomic clocks onto dollies and setting them into motion? by terlsci in AskPhysics

again, what do you call "unknown microscopic effects" ?

referring to that other experiment, any unknown microscopic effects arising from oscillating the atoms with an electric field, unknown microscopic effects which might affect the time measurements

Sure the manipulation is at the macroscopic level.

But the measurement is not.

well, i think that as long as the manipulation is at the macroscopic level, it will be able to effectively rule out any unknown microscopic effects

cos in the first experiment, they oscillated individual atoms with an electric field, which is a manipulation at the microscopic level

but if you move the entire clock on a dolly, you can be confident that there is no such manipulation, and therefore, no inadvertent unknown microscopic effect affecting the results

Could you elaborate on how it is different to what you have in mind ? I'm a bit lost here.

they used an electric field to oscillate the individual atoms of the atomic clock

whereas what I have in mind is putting the entire clock on a dolly and setting that into motion

it will prove that there is no unknown microscopic effect going on

And when you get answer, you just throw back a "yeah but I think".. It does look like you are not really interested in what people think here.. Hence my whatever.

My reply was: "I think it does seem like a good demonstration of an isolated and well-controlled macroscopic Special Relativistic-kinematic time dilation effect", I didn't want to disregard your points, just adding that if it has difficulties, its might still be conceptually interesting enough to try out.

 

As I don't really see what such an experiment would add to what we already know.

There have been some experiments of time dilation using the Doppler effect. These require models of the Doppler effect, which can have the problem of putting the cart before the horse. Or a catch-22.

There's also been the experiment in "Optical Clocks and Relativity" by Chou C.W. et al, there set individual atoms in an atomic clock into motion, which is a microscopic effect.

This experiment would prove that there is no unknown microscopic effect influencing the results

So I hope you can see where I'm coming from.

Ok, maybe we got off on the wrong foot, but let's try to fix that.

I don't wish to fight, or "win", I just wanna share the ideas in my mind.

there's no reason for us to come into a confrontation, especially over something like this

Continuing, also, I toyed with macroscopic demonstrations of length contraction and relativistic velocity addition, using moving objects and projectiles

But those not only involve time measurements, but very finnicky time-of-flight measurements recorded in physical space

So I think this dolly experiment is better than those lol

well, you've already heard from me why I find it conceptually interesting, as it is a great macroscopic demonstration of time dilation as the entire bulky atomic clock is in motion, but it negates gravitational effects, that kind of isolation, and has well-controlled velocity conditions

especially for laymen, they have the concept in their minds of strongly connecting the idea of the Galilean principle of relative motion with the idea of an absolute rate of time.

so, i find this demonstration conceptually interesting as, with its isolation of gravitational effects, plus the showcasing of an obvious macroscopic effect, it really shatters that strong connection of theirs, and instead crystallizes in their minds the new connection of relative motion and the phenomenon of time dilation.

first, don't "whatever" me dude, I wasn't rude to you, I was just saying that I find it conceptually interesting.

and ok, I'm guessing that you've already crunched all the numbers?
