Relativity of simultaneity Definition and 106 Threads

i wanted to say relevance but i figured that would be too easy :smile: editing there is something I'm not getting. yes if the speed of light is the same in all intertial frames simultaneity is relative but so what? can someone explain to me how this implies that time and space are relative...

My text reads thus (the part which is bolded is that which I don't understand, I just reckon that the rest is needed for the context) : This seems very wrong to me. Am I incorrect in saying that Mavis must see the two flashes simultaneously, and also must conclude that they happened at the same...

Is the relativity of simultaneity relative? I've been thinking about this for a while and this is really troublesome... The short question: Why can’t we draw the conclusion that simultaneity is relative only when events involving light/electromagnetic radiation are considered? The...

How can two events happening at the same time and place in one frame of reference happen at a different time and place in another frame of reference? For example: If you are standing at the side of a road and you see a car going at 0.6c and 8 light seconds down the road in both directions...

The classic example of demonstrating the relativity of simultaneity uses bolts of lightning striking two places "simultaneously". When you do the same experiment with sound then all observers can determine which event occurred first because sound does not follow the 2nd postulate of SR.

Hello everyone, I am new to this forum. In oct 2000 I submitted a paper to the European journal of physics on the non relativity of simultaneity. Essentially, the paper didn't deal with the theory of relativity, so much as it did with the issue of simultaneity. The paper was not...
