Talk:Special relativity/Definition

Theory of space and time? Or theory of motion? or?

"Theory of space and time" isn't really what it is, or arguably, it's not at all what it is. "Theory of motion" is more appropriate, as it really is about the effects of speed and it helps to distinguish from general relativity. We should compare different popular definitions and choose one of the most accurate, or a merge of two of the most accurate descriptions (To Be Done).

Broader still, I think: famously, it has something to say about mass and energy, which are not included in either of the above definitions. Peter Jackson (talk) 15:08, 15 May 2017 (UTC)
