    Proof that time <0 for tachyons > c

    1. Homework Statement Derive the result DeltaT <0 for U> (sqrt(1-v^2/c^2)+1)/v/c)c Homework Equations DeltaT = u/l + (u-v/1-uv/c^2)1/l Where: DeltaT is the time for the tachyon to go and come back. u is the velocity of the tachyon l is the distance that the tachyon goes v is the velocity...

    Why Are the Angles in a Minkowski Diagram Equal for Different Observers?

    1. Homework Statement In a diagram where I have two observers (one still (A) and one moving with a "v" velocity (B)), where the two parts disagre in the simultaneity of events, how can I prove that the angles of the B person axis that are put in the A person axis are equal. (/alpha=/beta , in...
