Tests of general relativity: Quiz


Question 1: [10][11] The measurement was repeated by a team from the ________ in the 1922 eclipse, with results that agreed with the 1919 results[11] and has been repeated several times since, most notably in 1973 by a team from the University of Texas.
Stanford UniversitySan Jose, CaliforniaSpartan Stadium (San Jose)Lick Observatory

Question 2: Einstein predicted the gravitational redshift of light from the ________ in 1907, but it is very difficult to measure astrophysically (see the discussion under Equivalence Principle below).
Gravitational waveIntroduction to general relativityGeneral relativityEquivalence principle

Question 3: Observations of pulsars in orbit around other stars have all demonstrated substantial ________ precessions that cannot be accounted for classically but can be accounted for by using general relativity.
Orbital periodApsisStandard gravitational parameterOrbital eccentricity

Question 4: It was known that it correctly accounted for the "anomalous" precession of the perihelion of Mercury and on philosophical grounds it was considered satisfying that it was able to unify Newton's ________ with special relativity.
Classical mechanicsForceNewton's law of universal gravitationGeneral relativity

Question 5: ________ are rapidly rotating neutron stars which emit regular radio pulses as they rotate.
PulsarBinary pulsarSupernovaMagnetar

Question 6: In general relativity, this remaining ________, or change of orientation of the orbital ellipse within its orbital plane, is explained by gravitation being mediated by the curvature of spacetime.

Solar SystemSunEarthStar

Question 10: The same effect may have been detected in the data of the Mars Global Surveyor (MGS) spacecraft[32], a former probe in orbit around ________; also such a test raised a debate[33][34].
