We need body rockin', not perfection
Let me get some action from the back section!!

That's why I only use Monster cables.

These higher power beams increase position accuracy but also increase back action, which is the uncertainty in the number of photons reflecting from a mirror that corresponds to a fluctuating force due to radiation pressure on the mirror, causing mechanical motion.

Yep.  That was my first question.  Such a precise device could detect someone farting clear across the country unless you have some bad-ass noise reduction.

Adult film star Alexis Texas, who is often inexplicably categorized as a big bust superstar.  Probably by
people who are standing on their heads.  Not she isn't quite healthy in the chesticalogical department but....

Read the whole farking article, and it was never made clear what part of the audio band!

What's the frequency, Kenneth?!?

Well, it's quantum, so, ultra high frequency?
