The legendary Higgs boson, also known as the God particle, was not formally discovered until 2013 by CERN’s Large Hadron Collider a couple years ago — but Homer Simpson had it all figured out years before, if you believe some people.

A 1998 episode of “The Simpsons” — a series which is still putting out new episodes even today — depicts Homer drawing up an equation that Dr. Simon Singh, a British popular science author who specializes in mathematics, says it very similar to the mass of the God particle, which is considered to be an elementary particle that explains some of the gaps in modern physics theory, according to an ABC New reports.

In the episode, titled “The Wizard of Evergreen Terrace,” Homer becomes an inventor and at one point draws an equation on a blackboard that, “if you work it out, you get the mass of a Higgs boson” that’s only slightly larger than the Higgs boson actually was, a full 14 years before its official discovery, according to the report.

However, it’s not a complete coincidence. Many of the writers for the show ere mathematicians, and the Higgs boson has long been theorized. The existence of the Higgs boson was first predicted in the 1960s by its namesake, Peter Higgs, to help explain how some particles get mass.

It was until 2013 when CERN’s Large Hardon Collider finally showed definitive proof that the long-theorized Higgs boson actually did exist.

The Wizard of Evergreen Terrace is the second episode of the 10th season of The Simpsons, which reached about 8 million households. It depicts Homer having a midlife crisis in which eh realizes he hasn’t accomplished anything.

The Higgs boson is an elementary particle in the Standard Model of particle physics that helps explain why some particles have mass even though the symmetries that control their interactions would require them to be without mass.
