> As for detecting gravitational waves, except for violent events like black hole mergers, we don't detect any; what few such gravitational waves there are are far too weak for us to detect. I thought LIGO and VIRGO had been detecting gravitational waves for the last 4 years pretty regularly (i.e. once a week).
