Roberts Roberts I thought you were cleverer than Superior Brother
Steve Carlip:

Superior Brother Steve Carlip, Aug 1 1997: "In special relativity, the
speed of light is constant when measured in any *inertial* frame. In
general relativity, the appropriate generalization is that the speed
of light is constant in any freely falling reference frame (in a
region small enough that tidal effects can be neglected). In this
passage, Einstein is not talking about a freely falling frame, but
rather about a frame at rest relative to a source of gravity. In such
a frame, the speed of light can differ from c, basically because of
the effect of gravity (spacetime curvature) on clocks and rulers."

Roberts Roberts in my view the last wisdom:

"In such a frame, the speed of light can differ from c, basically
because of the effect of gravity (spacetime curvature) on clocks and
rulers."

is EXTREMELY SILLY. What do you think? Do you find it EXTREMELY
CLEVER?
