New Lorentz transformation by Ngo Quang Ha
Ngô Quang Hà's new Lorentz transformation equation ensures that everything runs smoothly and eliminates paradoxes
The new transformation eliminated time dilation by replacing the factor k=γ with k=1. The formula retains only the time lag resulting from the finite—rather than instantaneous—speed of light signals
The new transformation fully satisfies the postulate that the speed of light is constant in all inertial reference frames. Furthermore, it ensures the Lorentz invariance of spacetime intervals.
