In physics, a "black body" is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. An approximate depiction of a black body is a hole in the wall of a large cavity. Any light entering the hole is reflected indefinitely or absorbed inside and is unlikely to re-emerge, making the hole a nearly perfect absorber. The film has been edited as a palindrome, and it is composed of fragments from a conversation with particle physicist Alessio Del Dotto. The scientist outlines the concept of "black body" by narrating anecdotes about it: ultraviolet catastrophes, the first moments of the universe, Borges' Aleph and the double meaning of the Italian word "spettro".
