We present a formal quantification of the “Bibliographic Event Horizon,” a phenomenon by which the first reference in any academic paper, [1], functions as a gravitational singularity. Following the seminal work of Specter [2, 3, 5, 8, 9, 12, 17], we establish that as the reference count (n) increases, the probability of the author having actually opened the source material of the references approaches the Planck length.
