In fact, as Breakthrough Listen Initiative astronomer Brian Lacki suggests, the universe could be teeming with billions of extraterrestrial intelligences (ETIs) — and, in a striking claim, all that activity just might explain “radio bright” active galaxies that emit powerful radio emissions across vast distances.

In a series of three yet-to-be-peer-reviewed papers, first spotted by Universe Today, Lacki raised the possibility that
