Now we can quibble about this and discuss how in Special Relativistic situations we can indeed have situations there "X caused Y" is true for some frames of reference and "Y caused X" for some other frame of reference, but this dilemma can be resolved by considering the effect of a finite speed of light whose "speed" is an invariant for all observers, e.g. generalcovariance.

`This wrong. SR shows that it can be the case "X is before Y" in one frame and "Y is`

`before X" in a different frame moving relative to the first frame. This means X and Y are`
