Why do astronomers seek to measure gravitational waves simultaneously with at least three detectors?
A) in order to measure their amplitude
B) because the waves evolve as they pass through Earth
C) because the waves have wavelengths much larger than Earth
D) in order to pinpoint the direction of their source

Question

Quizplus · Accepted Answer

Using at least three detectors allows astronomers to triangulate the source of gravitational waves, improving the accuracy of locating where the waves are coming from in the universe. This is crucial for correlating the waves with visual or other electromagnetic observations and understanding the events causing them.
