This is a comparison of einstenian and newtonian kinematics. In theA very thin vertical dipole with a ground plane behind it has a gain of
moving frame, the distance (0, x') is measured from an observer at the
origin of the frame at rest.

CASE: Light moving from 0 to x' in the moving frame.

Einstein SR. Light behave as wave, and c is the maximun speed.
>
c (t₁ - t₀) = c Δt₁₀ = v Δt₁₀ + x' ; PERCEIVED by observer at rest (no
speed addition).
(c - v) Δt₁₀ = x' ; Δt₁₀ = x'/(c - v) ; Mathematical time dilation
(by calculation).
c Δτ₁₀ = c (τ₁ - τ₀) = x' ; Δτ₁₀ = x'/c ; MEASURED by observer in the
moving frame
>
Δt₁₀ and Δτ₁₀ are different and depend on the observer location.

Newton. Light behave as corpuscles (photons?). It's allowed c + v
>
(c + v) Δt₁₀ = v Δt₁₀ + x' ; PERCEIVED by observer at rest (addition of
velocities)
(c + v) Δt₁₀ - v Δt₁₀ = x' ; Δt₁₀ = x'/c ; No time dilation (by
calculation).
c Δτ₁₀ = x' ; Δτ₁₀ = x'/c ; MEASURED by observer in the moving frame
>
Δt₁₀ and Δτ₁₀ are equal for observers at rest or moving at v speed.

In astronomy (Cassini, others), there are evidences that radar-ranging
experiments with Venus and Mars, the speed of light is added to the
speed v (between Earth and these planets). Known since 1965.

That c+v is possible destroys relativity and cosmology, as Hubble's
results have to be RE-INTERPRETED.

It's hard for relativists to accept this, as 110 years of lies with
einstenian physics COLLAPSE completely.
