Every time I revise the problem of the relativity explained by Einstein with respect to the fallen rays on the embankment I leave surprised as a scientist of his category could reach to similar conclusions and stiller, that many important scientists had seconded these conclusions without less contradiction. It is incredible.
Let us see the problem:
Let us locate at certain time according to the drawing. Spain place and Spain time: 13 hours 25 minutes 39 seconds and 25 thousandth of second of any day.
In this hour and on an embankment (example of Einstein) inside the Spanish territory two rays fall, which are simultaneous to fall at this hour, since the Spain time is common for the embankment, for the train and for the whole Spanish territory.
But not alone they are simultaneous between them, but with any other thing that happens in this hour on the Spanish territory, that is to say, they are simultaneous with millions of events.
If now we locate fifteen observers in different positions: Close and far from the embankment and inside the train that goes by the embankment, we can have the following conclusions:
1) If the observers are stupid or without physics knowledge, each one of them will give us different version about the event depending on its situation; even if one of the observers is blind and alone he can listen the thunder, he will tell us that the event happened quite after than this event occurred really.
2) But if they are intelligent and they have enough knowledge on physics, each one of them will adjust its situation with the speed of light and the speed of the train (or the speed of sound in the case of the blind man), reaching the conclusion that the rays fell simultaneously.
Therefore the simultaneity doesn't depend on who observes it, but of the global time in that the events happen.
To explain the principles exposed in the previous page we will give an example in which we understand the simultaneity of two distant events of which we cannot check their specific simultaneity but we understand that this simultaneity exists.
Are two people taken as example of systems of coordinated in movement.
These people inhabit the same city (Malaga) but one lives to the east of the city and the other one to the west, and they are not known themselves neither they have any contact between them. Therefore they can be considered as two coordinate systems with their own relative spaces and their own relative times.
To justify the principles before mentioned, we will take a space-time enclosure that is superior and common for both, which will be as space the city of Malaga and as time the 26 day of September of any year.
This day each one them will develop its own life, its work, its leisure, etc. Nevertheless and when being alive and to exist both during that day (September 26) it doesn't have any doubt that in any moment of this day each one of them will be making something that will coincide with what the other one is also making.
Therefore we know that during the whole day they will be making simultaneous things.
We know that there will be coincidence of acts carried out by both, although clear, we (and they) will never know which will be the coincident acts because we don't have the adapted media for it.
Therefore not being able to demonstrate the simultaneity of the different physical events doesn't mean that this simultaneity doesn't exist; it simply means that we don't have the appropriate media to check it.
So that, it remains clear that the simultaneity exists inside a superior enclosure that embraces appropriately to the two enclosures where the events are developed.
In the drawing it is exposed the demonstrative example graphically.
