I posted about this on a muber of threads, but answers I red didn't really made me clear some confusion about this, so I apologize in asking about this but I'm just hoping of a convincing answer.
In talking relativity, most examples are given without any reference to our everyday lifes, since Earth is clearly a non-rotating frame which is rotating and undergoing circular motion around the sun. In inertial frames, the definition of simultaneity is standard and pretty clear. On the other hand, the definition of what events are simultaneous to anything on Earth is pretty vague, and the same applies to length contraction and time dilation here on Earth. So again, I apologize for bringing this up, but is there a clear example or convention that strictly applies to Earth which is rotating and circulating at the same time, or do we have to consider Earth as an isolated rotating system first and then as an isolating system that is revolving around the sun to define the relativistic effects?
Thanks in advance, analyst
