Hi Greg,

I think you miss understood my questions, so let me try to simplify my query for you.
In 1919 a scientist named Eddington went to a place called Principe to measure the passing star light deflection caused by the gravitation of the sun. Because of this measured defection seen during a solar eclipse, Einstein's General Relativity Theory was proved correct.
My questions are in regard to that experiment.
How can the sun radiate light from itself and at the same time gravitate light from a distant star when all light is of a constant energy or velocity of C?
Perhaps C is not so certain as we are lead to believe. And, perhaps the flaw is measure?
Does the energy of light = mass times the constant speed of light in a vacuum squared?
What is the mass or weight of light, of a photon, of a quanta?
And if you can't measure the mass of one photon, how much mass is in a room full of light?
Do you have to stop it to measure it, and will that change it?
Is that like Heisenberg’s Uncertainty Theory?
Conversely, how would you measure a photon at the speed of light?
What does a photon look like?
Can you draw one for me?
How big is a particle of light?
Are you sure we can measure the speed without knowing what light simply is?
How do you measure the speed of star light?
How do we know that all star light is the same, or of a constant propagation?
Have we measured every star in the universe?
The problem Greg, is I really don't believe that the before mentioned experiment has any validity at all, do you?
And I am having the same trouble with C.

Thanks Greg, I hope that helps,

Obviously, the sun is a star, but surely like planets, not all stars and perhaps not all light is the same.
