- Two events cannot happen in the same location. The location is a point in space. Two events may happen at the same point but not at the same time. Two events may happen at a single point in different times. Therefore it is irrelevant to the issue of simultaneity.
- Can simultaneity exist when two events happen at two different locations. There should be a method of measuring the time of occurrence for these two events in order to see whether two events are simultaneous.
- A solution is the one proposed by Einstein in the thought experiment of lightning bolts string two points of a moving train. If you fine tune the experiment we have to consider two photons emitted at two different points received by an observer at the midpoint. If the two photons reach the observer at the same instant we can say the two events that produced the photons are simultaneous.
- There are serious lapses in the earlier experiment.
- First we state that a concept called "simultaneity" exist. This concept is not "two events happen at two times and these two times are very close". Because this is not a concept it is just a statement. We can make such statements on anything. And there is no seriousness in these statements.
- If we say given two points there exists a single point called midpoint. This cannot be proved ever.
- Photons travel at the velocity of light. And according to quantum theory exact time of arrival cannot be ascertained.
- Therefore simultaneity is a priori concept. It cannot be proved to exist by using empirical methods. Worse than that even a thought experiment cannot be performed to show it exist. There is life after death is a priori statement. But a scientific theory like special relativity being based on such a concept is almost absurd.
I started reading philosophy. And found out most of what I was thinking before are connected to it's subjects. I thought to jot down here, notes, as I read. Further, I have a liking on Physics, some notes are added about that subject.
