The observed frequency change agreed with the relativity prediction within 5%." According to your equation f'= f(1+V/c^2) V(a) and V(b) for the tower base and tower top is: G = 6.67E-11 M = 5.97E+24 ra = 6378000 Tower base radii rb = 6378023 Tower top radii (+23 meters (74 feet) high) Va = G * M / ra ^ 2 = 9.7888378648735791276869837432118 Vb = G * M / rb ^ 2 = 9.7887672652959533370556770582427 > [Eric Gisse] Potential energy is GM/r, idiot. You wrote down force. [snip remaining] > [hanson] It is not very clear what Potential *energy* Eric is talking about and for that matter what force. When I look at Eric's equation of Potential energy = GM/r where presumably G = L^3*M^-1*T^-2 then Eric's Potential energy becomes a phenomenon, an event, with the dimension of L^2/T^2, a squared velocity, which is as mysterious as are Keon's "y-rays"... but both of which appear to produce a mutual benefit for the mysterious term of "idiot". Thanks for the laughs, guys... ahahahaha... ahahahanson
