→More regarding the criticism of LIGO
:::: Maybe it is unfair to say that LIGO has been unsuccessful. But what about Gravity Probe B? That experiment seemed like a big expensive flop to me. [[User:RSchlafly|RSchlafly]] 02:26, 27 March 2009 (EDT)

:::::I just want to make sure that the people here criticizing LIGO understand that the frequency range of the gravitational waves it was built to detect predict a variations in spacetime by only a factor of 10^-21. LIGO's longest vacuum tubes are 4km long. So physicists are attempting to measure a change in length approximately 1/2500th the diameter of an atomic nucleus.
And to the poster who linked to youtube video of "gravity waves". Those ARE NOT gravity waves. Those are clouds.
