Question

Question 9

One of the key early tests of Einstein's General Theory of Relativity was

the bending of the path of starlight and resulting apparent shift in the position of stars because of the Sun's mass.

sending a twin in a spaceship to the nearest star and back at a high Lorentz factor.

the Michelson-Morley experiment.

measuring the time dilation effect from gas falling into a black hole.
