Fermilab is Building a 'Holometer' to Determine Once and For All Whether Reality Is Just an Illusion | Popular Science: But unlike conventional interferometers, the holometer will measure for noise or interference in spacetime itself. It’s actually composed of two interferometers – built one atop the other – that produce data on the amount of interference or “holographic noise.” Since they are measuring the same volume of spacetime, they should show the same amount of correlated jitter in the fabric of the universe. It will produce the first direct experimental insight into the fundamental nature of space and time, and there’s no telling what researchers delving into that data might find out about the holographic nature of the universe.
