Target entity: Satellite Test of the Equivalence Principle
Context triple: [STEP (Satellite Test of the Equivalence Principle), fullName, Satellite Test of the Equivalence Principle]
  • A. STEP (Satellite Test of the Equivalence Principle) chosen
    STEP (Satellite Test of the Equivalence Principle) is a proposed space mission designed to test Einstein’s equivalence principle with extremely high precision by comparing the free fall of different materials in orbit.
  • B. Gravity Probe B experiment
    Gravity Probe B experiment was a NASA-led satellite mission designed to precisely measure how Earth's gravity warps space and time, providing a high-accuracy test of key predictions of Einstein's general relativity.
  • C. Einstein’s 1907 equivalence principle paper
    Einstein’s 1907 equivalence principle paper is the seminal work in which Albert Einstein first proposed the equivalence of gravitational and inertial mass, laying the conceptual foundation for the later development of general 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. 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.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
