Can Gravitational Waves Stretch And Squeeze Space As They Pass?
š” The Answer
- Gravitational waves are ripples in spacetime caused by massive accelerating objects.
- As they travel, they alternately stretch and compress space perpendicular to their direction.
- These distortions are incredibly tiny, requiring laser interferometers like LIGO to detect.
- The first direct detection in 2015 confirmed a prediction of Einstein's general relativity.
