Gravity deviates its trajectory but neither slows it down nor speeds it up...

Ah well that's why when we don't know if a person is intelligent or not then it's an ESTABLISHED FACT to rule him IDIOT eh...
when it is not measurable...
Pathetic!
" Gravity deviates its trajectory but neither slows it down nor speeds it up... "
In the expanding Universe the photon emitted is "slowed down", because supposedly it tends towards the Red...suppose that;
But...if the Universe does NOT expand, and ON THE CONTRARY it is then the Stellar “Electromagnetic” Mass which slows down the Photons by Interferences...
(which you can also call "faux-tuna" if that tempts you...)
(I wonder who is going to run after the stars to measure each time how many more light years they are...)
(besides, even if the Light is slowed down, then the measurement is distorted...lol.)
