R.H.BTW, your equation above is wrong.What do you say, Paul?
It should be:
Vapp = v⋅sin(μ)/(1 - (v/c)⋅cos(μ))
where μ is the angle between the observed object's
velocity and the line of sight.
That is because we can only observe the transverse
component of the object's velocity.
If the object is coming right at us, μ = 0⁰, and Vapp = 0.Note that v_app > c when v > c/(sin(μ)+cos(μ))What's the matter with you?
Are you drunk, or just insane?
