Two events, A and B, are separated in space. In one frame of reference, event A occurs first and is seen to cause event B. Is it possible to find other frames of reference where event B occurs before event A?
If the order of two events does depend upon the frame of reference, is the interval between the spacelike or timelike?
The Attempt at a Solution
For the first part, I have said that it is possible to have a frame of reference where B occurs first. But I am not quites sure on the second part. I tried searching for the definitions of Timelike and Spacelike, but could seem to find any.
Any help would be most appreciated,
