Question

In 2022, Jun Ye’s group detected a form of this phenomenon over a distance of just 1 millimeter in ultracold strontium. The TCB and TCG coordinate systems are useful for calculations because they are unaffected by this phenomenon. This phenomenon causes an effect named for Irwin Shapiro (-5[1])whose magnitude is proportional to the Schwarzchild radius. The strong (10[1])equivalence principle implies both gravitational redshift and the gravitational form of this phenomenon, which was measured on a pair of airplanes in the Hafele–Keating experiment. GPS satellites must account for this phenomenon to accurately compute signal delay. This phenomenon implies that a sibling on a rocket ages less (10[1])in the twin paradox. For 10 points, name this relativistic phenomenon that causes moving clocks to tick more slowly. ■END■ (10[1])

ANSWER: time dilation [or gravitational time dilation; prompt on gravity or gravitation or relativity until read by asking “what specific phenomenon?”; accept gravitational redshift or gravitational blueshift until “redshift” is read; prompt on redshift or blueshift until “redshift” is read]
