Hey guys, this might seem like yet another basic question, but I was wondering about RoS. The impression that I got from reading about relativity was that relativity of simultaneity was a consequence of Lorentz contractions, primarily time dilation. Someone else made the point [emphasis is theirs, not mine] This was effectively how I understood it, but in a discussion on here I was told that wasn't the case. As with the other concepts of relativity I'm trying to get a better understanding of it. To try and illustrate my own understanding of it: if everything in the universe was at rest relative to each other, then there would be absolute simultaneity, but I thought that if an observer started moving relative to that previous rest frame then they would encounter time dilation and relativity of simultaneity would occur. It thought that RoS was a result of the time dilation. Just wondering what I'm missing, and if there are any online resources that clearly explain the distinction between RoS and Lorentz contractions, and how they are different from each other?
