A fiddly job but someone at Fermilab is doing it:
Now Chou and his team are down in the dirt, hunting for the universe’s quantum bits. In length terms, these bits are expected to be on the smallest scale of the universe, the Planck scale: 1.6 x 10-35 meters. That’s roughly 10 trillion trillion times smaller than an atom; no existing instrument can directly probe objects that small. If humanity could build a particle collider the size of the Milky Way, we might be able to investigate Planck-scale bits directly.
…
“Right now, so little experimental data exists about this high-energy scale that theorists are unable to construct any meaningful models other than those based on speculation,” Chou says. “Our experiment is really a mission of exploration—to obtain data about an extremely high-energy scale that is otherwise inaccessible.”
Chou thinks the universe might not be 3D but a 2D hologram.
Actually the 2D idea, in itself, has been done before, in a 19th century novel called Flatland.
What if the universe turns out to be fiction? Can Fermilab still fund the research?
