nature video | The future of detecting gravitational waves: A three minute guide @NatureVideoChannel | Uploaded August 2024 | Updated October 2024, 6 days ago.
Observatories, experiments and techniques are being developed to spot ripples in space-time at frequencies that currently can’t be detected. LIGO and Virgo are laser interferometers: they work by detecting small differences in travel time for lasers fired along perpendicular arms, each a few kilometres long.
But physicists are also exploring entirely different techniques to detect gravitational waves. These strategies, which range from watching pulsars to measuring quantum fluctuations, hope to catch a much wider variety of gravitational waves, with frequencies in the megahertz to nanohertz range.
