Shapiro Delay
The 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.

Famous quotes containing the words shapiro and/or delay:
“Sentio ergo sum: he feels his way
And words themselves stand up for him like Braille
And punch and perforate his parchment ear.”
—Karl Shapiro (b. 1913)

When long delay has given the evil strength.
Haste then; postpone not to the coming hour: tomorrow
He’ll be less ready who’s not ready now.”
