Question

Quizplus · Accepted Answer

The method of exoplanet detection based on Einstein's General Theory of Relativity is microlensing. This is because microlensing relies on the gravitational lensing effect predicted by the theory, which occurs when the gravity of an object (such as a planet) bends the light of a background star and causes it to appear brighter. By monitoring these changes in brightness, astronomers can detect the presence of an exoplanet.
