Question 12 • LVA-Earth and Space Science - FALL

Which list provides evidence for the general theory of relativity?

Answer
A
constancy of the speed of light, gravitational redshift, gravitational lensing
B
changes in a planet’s orbital path, curvature of space-time, length contraction
C
gravitational lensing, constancy of the speed of light, curvature of space-time
D
gravitational redshift, changes in a planet’s orbital path, gravitational lensing

Explanation

Evidence for general relativity includes gravitational redshift, the bending of light by gravity (gravitational lensing), and small changes in planetary orbits, such as Mercury’s perihelion shift. These are observable effects predicted by the theory. The constancy of the speed of light is a principle associated with special relativity, not observational evidence specific to general relativity.
