Measuring shapiro time delay
Did you know?
WebThe Shapiro time delay effect, or gravitational time delay effect, is one of the four classic solar system tests of general relativity. Radar signals passing near a massive object take slightly longer to travel to a target and longer to return than they would if the mass of the object were not present. WebSep 8, 2002 · If we could measure the effects on the Shapiro delay to order (v/c)^2, then we could test the speed of gravity. But these effects would be at the thousandths of a picosecond level, hopelessly small. The real way to measure the speed of gravity is to detect and study gravitational waves. By comparing the arrival of a gravitational-wave signal ...

This was first done by Irwin Shapiro (Shapiro et al. 1977, JGR, 82, 4329), and most recently done by Bertotti, Iess & Tortora (2003, Nature, 425, 374-376) In a very real sense, the delay experienced by light passing a massive object is responsible for ...
When the Earth, Sun, and Venus are most favorably aligned, Shapiro showed that the expected time delay, due to the presence of the Sun, of a radar signal traveling from the Earth to Venus and back, would be about 200 microseconds, [1] well within the limitations of 1960s-era technology.
