Target entity: Kennedy–Thorndike experiment Context triple: [Roy J. Kennedy, notableWork, Kennedy–Thorndike experiment]
-
A.
Kennedy–Thorndike experiment
chosen
The Kennedy–Thorndike experiment is a classic test of special relativity that examined the constancy of the speed of light using an interferometer with unequal arm lengths and varying laboratory velocity.
-
B.
Ives–Stilwell experiment
The Ives–Stilwell experiment is a classic test of special relativity that measured the relativistic Doppler effect to confirm time dilation for fast-moving ions.
-
C.
Michelson–Morley experiment
The Michelson–Morley experiment was a landmark 1887 physics experiment that attempted to detect the Earth's motion through the hypothesized luminiferous aether and whose null result helped pave the way for Einstein's theory of special relativity.
-
D.
Hafele–Keating experiment
The Hafele–Keating experiment was a 1971 test of Einstein’s theory of relativity in which atomic clocks were flown around the world on commercial airliners and compared with stationary clocks to measure time dilation effects.
-
E.
Fizeau experiment
The Fizeau experiment was a pioneering 19th-century physics experiment that measured the speed of light using a rotating toothed wheel and helped establish light’s finite velocity.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
Provenance (3 batches)
The batch behind each pipeline step, in order, with when it ran. Timestamps are batch-level — stages were processed in waves, so the object chain (NER → NED1 → NEDg → NED2) reads in order, but predicate / elicitation batches can sit in a different wave.
