I guess you did not find my allusions to the SMetric very useful to
find the Huyghens bending of light.
In Dual Space theory it's clear as a bell. I would be pleased to show
you how my gravity law solves this as well as the Pound Rebka
conundrum, if you think it would be useful.

If you have something to say, write an equation.
If you have nothing to say, write an essay
