Hogan’s holometer: Testing the hypothesis of a holographic universe

Looks like the interferometer is now the physicist's favourite tool.
It's being used everywhere from detecting gravity waves to quantum-space
vibrations for a hypothesized "holographic universe". Of course in this
case, they don't call it an interferometer, it's called a "holometer",
but it's the same thing -- the *exact* same thing.

"The holometer’s precision means that it doesn’t have to be large; at 40
meters in length, it is only one hundredth of the size of current
interferometers, which measure gravitational waves from black holes and
supernovas. Yet because the spacetime frequencies it measures are so
rapid, it will be more precise over very short time intervals by seven
orders of magnitude than any atomic clock in existence.

“The shaking of spacetime occurs at a million times per second, a
thousand times what your ear can hear,” said Fermilab experimental
physicist Aaron Chou, whose lab is developing prototypes for the
holometer. “Matter doesn’t like to shake at that speed. You could listen
to gravitational frequencies with headphones.”

The whole trick, Chou says, is to prove that the vibrations don’t come
from the instrument. Using technology similar to that in
noise-cancelling headphones, sensors outside the instrument detect
vibrations and shake the mirror at the same frequency to cancel them.
Any remaining shakiness at high frequency, the researchers propose, will
be evidence of blurriness in spacetime."
