Frequently Asked Questions
How are gravitational waves detected?
LIGO uses laser interferometry to measure changes in arm length from gravitational wave strain.
Do gravitational waves carry information?
Yes, they encode details about the source: masses, spins, orbital parameters, and cosmological distance.
