The Betz Mystery Sphere Conspiracy Theory

The Betz Mystery Sphere Conspiracy Theory!

As something of a conspiracy nerd I’m ashamed to admit, I’d missed the story of the Betz Mystery Sphere. It somehow flew under my radar, so now we’ll learn about it together. Sound like a plan? Good, let’s do it!

What is the Betz Mystery Sphere?

The Betz mystery sphere is a strange round metal object that the Betz family found near their home in Fort George Island, Florida in 1974.

It’s a little smaller than a bowling ball, with a diameter of 8 inches but it’s at least 8 pounds heavier. Weighing in at a hefty 22 pounds.

The Betz family claimed the sphere moved on its own and even began making noises at one point.

The Betz firmly believed it was from outer space. Could it actually be a piece of alien technology?

How the family discovered the Betz Mystery Sphere!

After a brushfire destroyed a piece of their property in March 1974, the Betz family was inspecting the damage when they happened to come across the bizarre metal sphere.

At first they believed it was a historic cannonball from Florida’s Renaissance-era Spanish colonizers.

But the sphere was clean, free of corrosion, and shiny. Weaponry in the Spanish colonial time period would have been iron or stone—not stainless steel or silver plate.

Strange Occurrences Involving the Betz Mystery Sphere!

When the family took the sphere home, they said, it started to move by itself. Their accounts were of the sphere rolling by itself, making noises, and vibrating.


Terry, the son of Antoine and Gerri Betz, was playing guitar and found that the sphere reacted to the sound of the guitar and made a throbbing noise which scared the family dog.

Popular Mechanics explains Things took an even odder turn when they were sitting on the floor and rolling the sphere towards one another. When it was rolled one way, it would change direction midway and head back to the person who rolled it.

In an April 1974 interview with the St. Petersburg Times, Gerri Betz said when the family dog got next to the sphere, “she began to whimper and cover her ears with her paws, something I’ve never seen her do before.”

The Betz family suspected solar radiations affected the sphere, which may have been why it reportedly moved “intensely” when the sun shone brightly, according to Wonderful Engineering. Eventually, the U.S. military got their hands on the sphere to analyze it for more answers.

When Carl Willson from a research firm in Baton Rouge, Louisiana examined the sphere, he “found radio waves coming from it and a magnetic field around it,” Gerri Betz told the St. Petersburg Times.

Then, the U.S. Navy analyzed the sphere at Jacksonville Naval Air Station. A Navy spokesman told the St. Petersburg Times that the Navy’s first X-ray attempts failed because its “machine wasn’t strong enough to penetrate the steel, but two subsequent tests showed the contents of the globe.”

“I don’t know who manufactured it,” the spokesman said, “but I say it came from Earth. We do know it is not an explosive and presents no hazard.”

The Betz family then sent the sphere to astronomer and renowned ufologist J. Allen Hynek for examination, but he also agreed the object was manmade.

Ok, If it’s made by humans, what was it?

Some authors, believing it fell from outer space, have suggested that it was Sputnik, or a Sputnik-like satellite.

This was largely based on what Carl Willson had said, that it transmitted a radio signal. But the ball was a poor match for Sputnik. It had no antennae, seams, rivets, mechanical connections, or anything else that characterized Sputnik’s globe.

Some other explanations were offered, that perhaps it was a pig used for cleaning out big pipes, or a mandrel ball used in bending conduit.

The truth comes to light about the Betz Sphere.

Skeptoid claims the Betz sphere was nothing more than a ball check valve used in large factory pipes.

Skeptoid even claims they found out how it ended up on the Betz property.

An artist made a run in his VW bus a few years before the Betz family found the sphere. He was collecting scrap metal for his sculptures. A friend had supplied him with a number of balls from large industrial ball check valves at his company, in two sizes: some 8-inch balls weighing about 22 pounds, and some 10-inch balls weighing about 70 pounds.

Having no room left inside the VW, Durling-Jones put the balls on a luggage rack up on top. He drove through the Jacksonville area around Easter of 1971, at which time a few of the balls rolled off the luggage rack and were lost. And there it sat for three years until the Betzes happened along.

Awfully convenient how they tied this conspiracy theory up in a nice little bow. I would normally feel an urge to disbelieve them but in this case it feels like they are probably right.

Conclusion to the mystery of the Betz Sphere!

This story is the perfect example of why you can’t believe everything you hear about situations like this. People so desperately wanted the sphere to be special they exaggerate the truth.

Always search for the truth, even though it’s usually less exciting than the stories.
