[Note: This post has been edited slightly since it was first published, to clarify the difference between sound waves and radio waves. I have also posted several updates in the Comments section of this post, where I present my reconsidered views of what the “Global Hum” may be. I recommend reading those updates after you read the main article.]
Everything new under the sun begins as an anomaly; but not everything thought to be new is genuinely new. Everything new and anomalous, if studied in the right way, can be explained; but it may take years of creative trial and error before we know what that “right way” is.
Those might be the twin mottos of the research field known as anomalistics — a field I’ve been interested in, without necessarily knowing it, since I read J. Allen Hynek’s book The UFO Experience at about age twelve. Hynek was the astronomer and scientific skeptic appointed to consult the U. S. Air Force on their Project Blue Book, started in 1952 to scientifically analyze UFO-related data and determine whether they indicated any threat to U. S. national security. Over the course of a few decades, Hynek came to believe in the reality of something he called the “UFO experience,” while never quite accepting the main explanations of that experience ascribed to it by the majority of its experiencers. (Briefly, the two predominant explanations are known as “ETI,” or the Extraterrestrial Intelligence explanation, and “EDI,” or the Extradimensional Intelligence explanation.)
The anomaly I’ve become particularly interested in recently is one known by some as “the Hum,” or “the Global Hum,” and it is one that I believe is somewhere on the trajectory of going from anomalous to explained. It’s also one that I believe has implications for how we think of the Anthropocene.
