This image shows a closeup of the Fermi National Accelerator Laboratory’s Holometer, an experiment designed to test the information storage capacity of the universe, and determine whether we live in a 2-D hologram.

Holometer studies the quantum character of space itself with unprecedented precision—laser light passing through an arrangement of mirrors will show whether space stands still or whether it always jitters by a tiny amount, carrying all matter with it due to quantum-geometrical fluctuations. The experiment will help us understand space and time better: what they are made of and how they relate to matter and energy.

Fermilab works on the world’s most advanced particle accelerators and digs down to the smallest building blocks of matter, probing the farthest reaches of the universe and seeking out the nature of dark matter and dark energy.
