[...] But it gave to thworld three rather startling predictions :--- (a) the advance of the perihelion of mercury (b) the deflection of light in the gravitational field of the sun and the stars and (c) the red shift of light from the sun and the stars none of which could be ex-. plained from the Newton-Galiito mechanico.
