Einstein for Everyone
The relativity of simultaneity is a complex idea that Einstein believed according to this thought it made it so, inertial observers in relative motion disagree on the timing of events at different places. Meaning that one observer may think that something is happening simultaneously but another may not. For this you have to be aware of the space and time with reality and how it can be manipulated to give unrealistic senses of reality.
The relativity of simultaneity is not saying that two spatially separated events are simultaneous and neither observer has made a mistake. It is however, referring to an internal factor that allows for time to be preserved differently. By changing the factors of the observer being in motion or not in motion makes them perceive the events of time differently.
In Special Relativity I do not think that it makes time "unreal". I believe that it can manipulate time to be perceived as less of a thing and more conceptual but that does not make it unreal. Time is real but that does not mean that it can't be experimented with to make others perceive its occurrence differently. In the case with clocks A and B, time got manipulated in the fact that when the observed was moving time seemed to be moving so the clocks were not synchronized. However, when the observer was standing still they perceived time to be in sync. This dose not make time less real it just is making it an object that can be changed.
Hi, Grace. I think it's interesting how when you reframe the definition of relativity of simultaniety, it means that as human observers, we make inherently subjective judgement's based on our observations and perception. Our ability to make different judgements on the timing of events and when they occur is biased, due to the fact that our position influences when a wave, whether it's a light wave, sound wave, etc., arrives. However, it isn't exactly possible to remove our bias, even if we has a machine or some instrument to measure waves for us - it would still take the same amount of time for a wave to reach it. However, its still important to acknowledge this bias we have, as it may be possible to then correct our observations in light of this bias (for example, knowing that a lightning strike's flash and sound start travelling at the same time, but take different amounts of time to reach us).
