Hi Tom_Potter,
Did Galileo know about " ( 1 - v^2 / c^2 )^-.5 " and c's invariance ?
As I just old Kenseto...
The easiest way to understand General Relativity is
to think in terms of time and energy.
When sync'ing G.P.S. birds with our network of terrestial clocks,
the photons fall into the gravity well, blue-shifting
( i.e. they get more energetic, with shorter wavelengths ) and
the centrifugal force ( in the opposite direction ) red-shifts them
( i.e. they get less energetic, with longer wavelengths ).
Net, the photons blue-shift.
The blue-shifted photons alter the S.I. meter and second.
General Relativity models energies and shifting standards,
accounting for distances, densities, pressure, centrifugal force, etc.
