I´ve seen that for spacelike intervals, ie [itex] s^2 < 0 [/itex] you´re able to swap the sign of s = x-y = y-x. Why is that?

Thanks!

Take the axis which is 45° between x and y. Rotate 180° about that axis. Now you have swapped x and y, and since every rotation about that axis less than 180° is also a valid transform, the transform is continuous.
