You're not quite understanding the setup.

@RudeBoy9179 Hello, we have no doubts at all about us "understanding the setup". Have a look a our website, indicated in the video. You then see how far that understanding goes... Multilple flaws exist in contemporary paradigms, demonstrated by theory & experiment. As with many paradigms in the history of science (Thomas Kuhn) it will take a new school of the new paradigm. Then progress can be made. One day others will see and agree on (and start defending) those new views.

hello Bozeman. Thanks for your reaction. Your argument is the same as Mach's. However Mach was wrong : please take the time to read section 4.1 and section 5.1 at the indicated website in the video. Then you will understand. Moreover the situation as you depict was already explained there (Fig 19) since Obs1 and Obs2 are indeed put in space... Obs1 and Obs2 both have a device based on a laser (pulse/photons) and each of them is thus able to measure her/his own real (absolute) velocity vector !

Why are you assuming that Obs. 1's version of things is THE correct version? Put them all in space suits and remove the earth, and you can't say who is moving and who is stationary. Who is right then?

You are missing the point of the thought experiment. In the second frame of reference, A is the rear of the train car, B is the front of the train car, and M is a point midway between the two in the train car. In the second frame of reference, none of these points ever move. Your statement that "the train of course will have moved towards B and will not be in M" is not true in the second frame of reference.

@jfbolusThanks for the reaction but I am not missing any point. First read the original thought experiment of Einstein where the flaw can easily been seen, as explained in the presentation. Secondly, the variant of the thought experiment with 2 light pulses A/B from the back/front to the middle M does not change anything with respect to the fact that both pulses definetely NEED TIME to travel in REAL space. The artificial/mathematical "space" idea (x,y,z) in the human's mind causes the flaw.

When you plot out all the different time events you are doing this only from the point of view (POV) of Obs1. From the POV of Obs2, they do not need to know anything about the POV of Obs1. They can see things only from their own point of view and from their POV they are not even moving since there is no absolute difference between not moving and moving at constant velocity.

@PLazzar, have a look at the website indicated in the YouTube presentation. You learn about a three lasers set-up, in the three directions x, y and z (perpendicular). The locations of the photons from these lasers at the three measuring grids are dictated by the vx, vy and vz component of the set-up velocity vector. It is thus possible for Obs1 or Ob2 to measure their own values of vx, vy and vz ; thus their own velocity vector v ! See also a calculated case of a space ship at the website.

@ebrauns789 I will check it out. Did you look at the doc I emailed you yesterday?
