Unformatted text preview: c ′ ∆ − ′ ∆ = ∆ − ∆ The quantity ( ∆ S) 2 is a Lorentz invariant ( same in all inertial frames ). If ( ∆ S) 2 > 0 the two events A and B are said to be “timelike” and there exists an inertial frame where the two events occur at the same spatial point ( i.e. ∆ x'=0). If ( ∆ S) 2 < 0 the two events A and B are said to be “spacelike” and there exists an inertial frame where the two events occur simultaneously ( i.e. ∆ t'=0). If ( ∆ S) 2 = 0 the two events A and B are said to be “lightlike” they can only be connected by light (traveling at speed c). differentials...
