The result has since been refined by measuring the effect with distant space probes. In 2003, Bertotti, Iess, and Tortora used a signal sent to and from the Cassini probe to confirm the predictions of general relativity with an accuracy of 20 parts per million. (5/5)

According to general relativity, photons are deflected and delayed by the curvature of space-time produced by any mass1–3. The bending and delay are proportional to g 1 1, where the par- ameter g is unity in general relativity but zero in the newtonian model of gravity. The quantity g2 1 measures the degree to which gravity is not a purely geometric effect and is affected by other fields; such fields may have strongly influenced the early Universe, but would have now weakened so as to produce tiny— but still detectable—effects. Several experiments have confirmed to an accuracy of,0.1% the predictions for the deflection4,5 and delay6 of photons produced by the Sun. Here we report a measurement of the frequency shift of radio photons to and from the Cassini spacecraft as they passed near the Sun. Our result, g 5 1 1 (2.1 6 2.3) 3 1025, agrees with the predictions of standard general relativity with a sensitivity that approaches the level at which, theoretically, deviations are expected in some cosmological models.

Als je nog andere dingen voor de feestdagen wil bestellen zoals #Noordzee kabinetjes (€23,50) of #basterkabinetjes (€59,95/€69,95) of #Schelptekeningen (€59,95 geloof ik) dan kun je dat ook al aangeven in DM want ik weet niet of ik overal genoeg voorraad van kan maken
