10 Simultaneity
The first chapter of Einstein’s 1905 paper has the heading Definition of Simultaneity. The choice of this heading indicates the point of departure and the direction of the initial thrust of the Einsteinian argument. The concept of time has been chosen as target, and it is its fundamentality and universality which has to be demolished. After briefly introducing the notion of a Newtonian mechanical System, Einstein says: If we wish to describe the motion of a material point, we give the values of its co-ordinates as functions of time. Motion is a function of space as well as time, but the question of space is not analysed in Einstein’s discourse on special relativity, although it is obviously just äs important as the question of time. The argument continues: A mathematical description oft his kind has no physical meaning unless we are quite clear as t o what we understand by „time“. The word „time“ is now placed in quotations marks indicating that Einstein is not prepared to concede that the concept of time is entitled to exist in its own right and to be considered as a primary and basic component of physical reality together with space. This denial of the real existence of time prior and apart from matter is one of the most persistent ideas of Einsteinian relativity.

It is repeated again and again by Einstein himself and by his followers, directly and by implication, because any admission that time is primary and universal would destroy the edifice of relativity. One of the most forthright Statements on the non-reality of time is contained in Einstein’s reply to continuous questions by uninitiated outsiders about the quintessence of relativity: It was formerly believed that if all material things disappeared out of the universe, time and space would be left. According to the relativity theory, however, time and space disappear together with the things.

Einstein’s view is derived from his metaphysical outlook and is not demanded by any physical requirements. Just as metaphysical is his reduction of the problem of time to a question about the simultaneity of two events. Einstein claims that all our judgments in which time plays a part are judgments of simultaneous events. Obviously, not all our judgments in which time is involved are of this kind. In fact, in most cases it is the past or the future, the sequence of events, cause and effect relationships, and the inescapable flow of time which are the substance of our judgments. Simultaneity is sometimes of importance, and when it is, the reconciliation of the times of two separated events has never created any physical Problem. Why is it necessary to attach such prominence to simultaneity and see difficulties where there are none? The difficulties arise only if the generally accepted principle of the independent and constant time-flow is rejected. Einstein does not find it necessary to offer a rational argument in favour of his point of view. In his opinion, it is not necessary to say anything about a non-existent principle, despite the fact that in reality he makes frequent use of it.

After having conceived the idea that time is nothing more than periodically recurring motion of matter, Einstein suggests that it might appear possible to overcome all the difficulties attending the definition of „time“ by substituting “the position of the small hand of my watch” for „time“. These words were written in 1905. Later, he cast away the cautious wording and said positively that by the time of an event we understand nothing else but the reading of a clock, i.e. the position of the hands of the clock, which is in the immediate vicinity of the event. This definition is considered by him entirely satisfactory when we are concerned with the determination of local time, that is, time associated with the place where the clock is located. It should be noted that Einsteinian time necessarily requires an observer to be present at the event, to be in possession of a clock, and to be able to read it. Only if these conditions are complied with is Einstein prepared to permit the use of the word „time“.

The timing of an event with a clock which is located at the event, and the Synchronisation of two clocks which are placed side by side, can be accomplished quite satisfactorily and does not present any difficulties, according to Einstein. But the situation is no longer satisfactory when we have to connect in time series of events occurring at different places, or to evaluate the times of events occurring at places remote from the clock (Einstein). The problem posed by Einstein is this: how do we compare and synchronise time measurements made at places which are remote from each other?
