# The error of interpretation of Einstein

**The error of interpretation of Einstein (explanation in a few words)**

**Why there can be no relativity of simultaneity at the physical level:**

Once it is understood that the invariance of the speed of light implied the relativity of simultaneity at the physical level, everything else follows. There are not thirty-six ways to define the relativity of simultaneity at the physical level, there is undoubtedly only one:** in the thought experience of the Einstein train, the two light rays are emitted at the same time for the observer at the railway station, and according to Einstein's interpretation, would not be emitted at the same time for the observer on the train.**

** For the observer at the railway station**, the two light rays are emitted when the two observers are at the same distance from the two light sources (when the two observers are opposite each other).

** For the observer on the train**, the light ray at the front of the train would be emitted before the light ray at the back of the train. For the observer on the train, when the two observers are at the same distance from the two light sources (when the two observers are opposite each other), the light ray at the front of the train would already have been emitted, while the light ray at the back of the train would not have been emitted yet. It will be emitted when the observer on the train is a little further away.

Therefore,** when the two observers are at the same distance from the two light sources **(when the two observers are opposite each other), **the light ray at the back of the train appears to exist at the back of the train in relation to the observer at the railway station and does not appear to exist in relation to the observer on the train **__( this is the relativity of simultaneity at the physical level)__. In relation to the observer on the train, it will exist when the observer on the train is further away, and he can be much further away if the light sources are very distant. This is what is involved in the thought experiment of Einstein's train, even if it is not explicitly stated. Just follow the reasoning to understand this.

And once the light ray has been emitted for him, if the observer at the railway station speeds up and joins the observer on the train before the light ray is emitted for the observer on the train, we find ourselves in the case discussed in the objection of the shuttle and the missile. **And we can see that it is impossible, as soon as we take into account the existence of the missile according to what is shown on the space-time diagram.** Of course, to get to that case, we have to consider very large distances.

__The relativity of simultaneity at the physical level is a principle implied by special relativity, it has a metaphysical range and it is not verifiable immediately____.__ On the contrary, it can be shown with certainty that it leads to contradictions (see the objection of the shuttle and the missile). This means that there is in fact an absolute simultaneity at the physical level, because there is no third possibility. The absolute simultaneity at the physical level is also a principle having a metaphysical scope, and it is not verifiable immediately either. Indeed, it is not possible to know for sure whether two distant events are simultaneous or not. But once it is understood that there is necessarily an absolute simultaneity at the physical level, this leads to a complete paradigm shift with respect to the conceptual system of physics.

__Objection of the shuttle and the missile__

The Space-time diagram of relativity does not correspond to what actually happens. This would also mean that the speed of light is not always invariant.

The diagram in the video is based on a ThM diagram (online physics forum http://www.forum2.math.ulg.ac.be/ ), expressing objection 2 of Chapter 1 from my book "Le Principe Moteur de l’Univers et l’Espace-Temps" ("The Driving Principle of the Universe and Space-Time"). I added this diagram in my new book "Et si Einstein s'était trompé sur un point capital dans son analyse aboutissant à la relativité restreinte?" ("What if Einstein was wrong about a crucial point in his analysis leading to the special relativity?")

__If we take into account what is involved in the relativity of simultaneity at the physical leve____l,__ we arrive at two contradictory calculations with regard to the position of the missile:

Let us imagine that the missile has already traveled 100 meters before the shuttle accelerates, the shuttle begins the first calculation of the trajectory of the missile from that point.

Once the shuttle has accelerated, it looks at the position of the missile on the space-time diagram and the missile has not left yet. It starts the second calculation of the trajectory of the missile while the missile appears to be still at its starting point.

__We can clearly see that the two calculations are not going to give the same moment of arrival of the missile, since according to the first calculation, the missile traveled more than 100 meters, whereas according to the second calculation, the missile has not left yet (these two calculations, at that moment, being made at the same time from the shuttle)__** .** This means that, if we follow what the space-time diagram says and if we take into account the existence of the missile, in some cases it is possible to have two contradictory mathematical representations with regard to the position of the missile. And the difference between the two calculations is due entirely to the belief in the relativity of simultaneity at the physical level, and is not due to inaccuracy in the calculation in relation to the trajectory. Of course, for this to be obvious as I have just described it, the missile would have to be hundreds of billions of kilometers away from the shuttle.

__Conclusion__

The relativity of simultaneity at the physical level is a principle implied by the special relativity, having a metaphysical scope. By taking into account the implicated metaphysical aspect (considering the existence of the body in accordance to what is shown on the space-time diagram), we reach two contradictory calculations concerning the position of the missile. This demonstrates, even from a mathematical point of view, that such a relativity of simultaneity is impossible. This means that there is an absolute simultaneity at the physical level in the absence of a third possibility (1). Therefore, the speed of light cannot be invariant in any case. From this point, it will be understood that this may lead the physics to an important paradigm shift with respect to its actual conceptual system.

Note 1: There is no third possibility, since, from the moment where we consider that such a body exists “to" A, either it exists also “to" B, or not.
