These ‘monster’ gravitational waves have supposedly been ‘spotted’ by calculating disparities in pulsar timings. The article didn’t have as much information as I was hoping - were any of these waves detected/confirmed by LIGO?
- gaoshan 3y agoIt's my understanding that LIGO is too small to be able to detect such waves, hence the use of pulsar timings.

- seventhson 3y agoThe wavelengths are too large for LIGO. The wave measurements were correlated with data collected from many pulsars. https://arstechnica.com/science/2023/06/nanograv-picks-up-signal-of-cosmic-choir-of-supermassive-black-holes/ https://arstechnica.com/science/2023/06/nanograv-picks-up-si...
- chorsestudios 3y agoThank you for this article link, I found it much more informative than the parent article. The video at the bottom was well made.
- bowsamic 3y agoAs others pointed out, LIGO is too small compared to the wavelength of the GW, but even if LIGO was extremely long, the technical noises (seismic, control system noises, gravity gradient noise, etc.) at such low frequencies are extremely high for ground-based detectors
