How Variable Speed of Light Explains Gravity

A little more technical account how GR tests are describes by VSL and how Newton's law is recovered.
14:18: c* is the lower speed of light IN the gravitational field, not OUTSIDE. Same for frequencies and wavelengths.
16:42: 1,75'' was not yet found by Einstein in 1911, but in 1915.
18:00 Discussing the blueshift wen photons fall into the gravitational field. The redshift occurs of course when the photons come out.
