LIGO is quantum
William G. Unruh
Since quantum mechanics was invented controversy has raged as to whether or not all things are quantum, or whether there is limit, a barrier above which things become classical. I will argue that recent experiments have shown that the 40kg mirrors in LIGO have been shown to be quantum, placing severe limits on any theory which purports to set limits ( like mass limits) on objects for them to be quantum.
