This Experiment may Explain Gravity and Dark Matter and the Red Shift all at Once

The worst Law on the books from Einstein... "Light speed is constant". Light can speed up and slow down and does.
"Modern physics is founded upon two pillars: quantum theory on the one hand, which governs the smallest particles in the universe, and Einstein’s theory of general relativity on the other, which explains gravity through the bending of spacetime. But these two theories are in contradiction with each other and a reconciliation has remained elusive for over a century."
I show Exactly how light and Gravity work TOGETHER.
