    What? What does that mean? I thought the mind experiment said that the observer on the train would measure them to arrive at different times, not just the observer on the station.

    Do you even know that the MMX was performed prior to Einstein formulating SR? It did not come along afterward and require changes in SR.

    Hello,Time for both of them are different.. You cannot compare like that.... I think you are confused...

    disatnce that they measure different,time,....

    That is the reason why different observers cannot agree on simultaneity.. see Simultaneous events are not simultaneous,though it reached at the same time for different observers!! By measuring in their own time frame!!

    It was prior to when Einstein came up with this mind experiment. He just did not know about it when that experiment was first done. I think if he knew about it then this mind experiment would have been stated differently to agree with the actual experiment.

    Actually for an observer inside,both beams hit at the same time.. but for outside,it didn't.i explained in the time of observer outside.. not inside.. Inside time is different...

    I think the events couldn't be simultaneous because if the beams reached the observer at the same time coming from opposite directions, then the same amount of length contraction and time dilation at the same location couldn't compensate for the speed of light to be measured to be the same from two beams crossing each other coming from different directions at the same location. So then then things couldn't be simultaneous, because there couldn't be different amounts of time dilation and length contraction for light beams crossing at the same location. I think it could be the only way to get around that problem.

    Please tell me in which frame of reference you explained this... Always explain like that..

    I don't think any experiments have been done that show that a M&M experiment would be observed to obtain different result from another frame. It would be like a space ship passing by, spireling out of control could then look down into a M&M experiment on Earth and watch scientist discovering that the M&M experiments is wrong.

    M&M experiment is not wrong.. an observer watched it in the frame who did not have earth's velocity... that is why he saw like this.. Did you see anywhere in the internet who explains M&M experiment in this frame???

    You didn't grasp simultaneity video correctly.. Al last in the video it said like this.. Who is right.Lightning strike at the same time or not.. Both are right,in their own time frame... Likewise also M&M experiment...

    That is the point I was trying to make, the M&M experiment is not wrong and hasn't been shown to be wrong from a different frame. So then assuming that the results of an M&M experiments would be different in another frame would be getting into the realm of psuedoscience.

    no way.. it is not getting into pseudoscience.. You just don't understand.. It takes time to understand.. You should a little bit hard..

    The M&M experiment says that an observer in motion would measure beams of light traveling the same distance to arrive at the same time while it is in motion. Einsteins thought experiment says that the observer on the train ( the one in motion) would observe the beams of light to arrive at different times. It is a clear contradiction between actual experiment and Einsteins thought experiment. It would be a good thing he backed it up by actually doing the maths!

    You think like that because no one tried this frame.. Actually it is tough to look at this frame.. But it doesn't mean that it is wrong.. I already explained this experiment with respect to train... Remember??? Second way is similar to this one.. This is testable..

    Both experiments are different.. i have modified the experiment.. read that experiment once more.. that experiment is similar to M&M experiment not Einstein's thought experiment. But my experiment is made by the conclusion of Einstein's thought experiment,so Both three are right...

    I think if Nasa decided to use a telescope to look into a M&M experiment being done on Earth, they would find that the M&M experiment got the same results. It might be possible that they observe the experiment to get different results and then see the scientist claim that they actually got the same result, but I don't think there is a good chance that would be the case.

    I already explained this as well as I can, I don't see how I could make it anymore clear. I got to go now.

    But they should stay at the same position!!! I am sure it willl be my side because Einstein is Very right!! It always make sense!! It is tested that Einstein's theory is right..
