arXiv.org > gr-qc > arXiv:0905.4803A cosmologist suggests a novel way to uncover the nature of spacetime on the smallest scales.
Cosmologist Craig Hogan ... has become enamored of a noise he claims is generated by something even tinier — a minuscule graininess in the otherwise smooth structure of spacetime.
Call it Hogan’s noise. Many physicists are skeptical, but if his hunch about the existence of this subatomic clatter proves correct, it could have a mind-boggling implication: that the entire universe is nothing more than a giant hologram.
What’s more, it would mean that the structure of spacetime on subatomic scales might soon be revealed.
