NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07
Target entity: Ives–Stilwell experiment
Context triple: [Herbert E. Ives, performedExperiment, Ives–Stilwell experiment]
  • A. Ives–Stilwell experiment chosen
    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.
  • B. Pound–Rebka experiment
    The Pound–Rebka experiment was a landmark 1959 physics test that measured the gravitational redshift of gamma rays in Earth’s gravitational field, providing one of the first precise terrestrial confirmations of general relativity.
  • C. Kennedy–Thorndike experiment
    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.
  • D. 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.
  • E. Trouton–Noble experiment
    The Trouton–Noble experiment was an early 20th-century test of the luminiferous aether that searched for a torque on a charged capacitor in motion and, by finding no such effect, provided support for the emerging theory of special relativity.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
