There is no way to prove (know) if it’s the lab moving or the observer

So the math is exactly the same

Everyone moving in relation to somebody else sees the other persons clock running slower

It doesn’t matter which person you pick as the observer


If you think about it, it can’t be any other way

It’s why the speed of light is always the same for every observer, no matter how “fast” or “slow” they are moving, which of course is in relation to something else that is moving, it doesn’t matter to the observer, they are always not moving from their perspective

(Remember this is movement, not acceleration)

The light bouncing back and forth between the mirrors doesn’t know there is any motion

Nor does it ever travel farther, no matter what the relative motion

It helps to realize the stationary lab with the two mirrors might be moving at a fraction of the speed of light, from some observers POV

But it’s relative motion


The lab and the mirrors are not actually moving at all, according to them

I don't disagree. Just show us that "the math is exactly the same", without hand waving. I. e. we need proof.

You have your implications backwards: it is because all experiments showed the constancy of the speed of light (in a vacuum) that the ether theory was ditched and special relativity introduced.

Are you implying that an accelerated observer measures a different light speed?

The math is exactly the same


https://www.pitt.edu/~jdnorton/teaching ... index.html





What happens depends on the observer, the unmoving observer in the thought experiment sees light traveling farther, but if you think about it, the lab can be stationary and the observer is moving

It has to be that way

The “moving” clock is not moving to the observer in the lab

Time is perfect and the light doesn’t travel any farther, even as the moving observer sees it does

It helps to realize no matter what the movement we ascribe to the lab and the observer, they are both moving in respect to something else

To an observer “not moving” at the center of the galaxy, they are both moving really really fast, which is why that observer sees both of them with slower clocks

Then there is the motion around the sun, and the entire frame is moving toward another galaxy, and that frame is rushing towards a great attractor

So the math gets more complicated

But to the lab, nothing is moving in the lab, except photons, at the speed of light

This is a basic part of the theory. Since there is no way to actually say, or know, who is moving or at rest, (everyone is actually), and the idealized rest state or observer location is a fiction, used to do maths, it doesn't matter which you say is moving.

The math is the same.

The perceived motion of the lab, (with the mirrors, the light, the time and distance), it is all dependant on the observer. And it doesn't matter if the lab is "stationary" and the observe is moving, the calculations are the same.

You already wrote that, twice, and I still don't disagree,

Yet no math. Prove your claim that it is "exactly the same" or admit that you're unable to do it.

Whatever the relative velocity of the observer is, just plug it in

You can have multiple observers at different velocities, observing the same lab

Each observer gets a different answer

The observer in the moving lab sees the exact same thing if the stationary observer also has mirrors and a light, and the moving lab is measuring the distance looking at the unmoving observer

Let’s cut to the chase

Does an observer in the lab see clocks running slower for the non moving observer! There is another light mirror set up where the non moving observer is

What does the lab observer see? The non moving observer appears to be moving

Which they are of course, relative to the lab

I’ve read Einstein and a lot of works on his theories, the reciprocal math is a fundamental thing, that is called In physics, the principle of relativity. It is the requirement that the equations describing the laws of physics have the same form in all admissible frames of reference.

I say the math used to calculate is the same for both frames of reference, in this puzzle.
