Why Did People Once Think the Moon was Made Out of Cheese?

Ron asks: Why did people think the Moon was made out of green cheese?

In the early days of Google Moon, when you zoomed into the Moon, it eventually showed a Swiss cheese surface

Because it was formed in the Milky Way? -badop-ting-… *crickets*

In fact, nobody ever thought the Moon was made of green cheese… Well, there are nutters out there, so it’s possible that there was at least one person who thought the Moon was made of cheese, and kids used to sometimes believe the Moon was made of cheese thanks to various fables, but kids will believe anything. For instance, in 1902 it was found that the most common theory as to what the Moon was made of according to children in the United States was that it was made of cheese. But these children weren’t exactly setting the bar high as other popular responses from them were things like “yellow paper, dead people, and rags.”

So other than lunatics and children who were told so by their parents via fables, nobody seriously ever thought the Moon was made of cheese.

Another common misconception surrounding the Moon/green cheese thing is that the “green” here is referring to the color green.  While there are actually green cheeses, what the “green” signifies here is “new” or “fresh”, so “the Moon is made of new cheese.”  This was a common way to refer to cheese where the whey either hadn’t yet all been pressed out or had just been removed from the curds, in other words, cheese that has not been aged at all.

So how did this “Moon is made of green cheese” thing all start and become popularized?  It isn’t entirely clear who was the first to come up with the expression, but it became extremely common starting in the mid-16th century. The credit for the person to come up with the expression usually goes to famed French monk and scholar François Rabelais or English writer John Heywood.

Heywood first used it in The Proverbs of John Heywood written in 1546

Ye fetch circumquaques to make me believe,
Or thinke, that the moone is made of greene cheese.
And when ye have made me a lout in all these,
It seemeth ye would make me goe to bed at noone.

So basically, the expression itself simply was used to refer to something so ludicrous that only the extremely gullible would believe it.

Another early example using the statement in the same way can be found in 1565 in Shacklock’s Hatched of Heresies:

Whilst they tell for truthe Luther his lowde lyes, so that they may make theyr blinde brotherhode and the ignorant sort beleve that the mone is made of grene chese

Yet another early reference from John Wilkins’ New World Book 1 (1638), which is explicitly clear as to the meaning of the expression and that it had become common,

You may as soon persuade some Country Peasants that the Moon is made of Green Cheese (as we say) as that ’tis bigger than his Cart-wheel

While in the early days it was used just to signify gullibility, in the last couple centuries many started thinking that people actually used to believe this, rather than that it was simply an expression.  This is not unlike how people started believing that most thought the world was flat during the Middle Ages, when in fact in many parts of the world scholars and people who were educated have known the world wasn’t flat for well over 2000 years.

For instance, Eratosthenes (at the time the head librarian at the library of Alexandria) around 240 BC not only knew the Earth was round, as most Greek scholars did at the time, but managed to become the first known person to calculate the circumference of the Earth accurately, only off by about 2%.  He also calculated the distance from the Earth to the Sun and was off by only about a half a percent.  Not only that, but he calculated the tilt of the Earth on its axis and was off by less than half a degree.   These were just some of the many amazing accomplishments of Eratosthenes, who I’ve been meaning to do an article on here for some time, but never seem to get around to it.  If I do at some point, forget you read this paragraph. ;-)   Another amazing accomplishment by Eratosthenes was that he basically invented the discipline of Geography with his remarkable three book treaties Geographikia.  OK, I’m done for real this time.

Bonus Moon Facts:

  • Contrary to popular belief, there is no “dark side of the Moon”.  The Moon has days and nights, just like Earth.  One Moon “day” is 29 1/2 Earth days.  This rotation coincides perfectly with its rotation around the Earth so that we always only see one side of the Moon.  Coincidence?  I think not!  Wake up Sheeple!
  • In truth, it really isn’t a coincidence and it wasn’t always this way.  When the Moon first formed, its rotation speed was very different than it is now.  Over time, the Earth’s gravitational field gradually slowed the Moon’s rotation until the orbital period and the rotational speed stabilized.  This effect isn’t unique to our Moon, but also to many of the moons orbiting various planets in our solar system.
  • Also contrary to popular belief, the Moon is not round, but rather is the shape of a party hat with the round bottom pointed at us… OK, I made that up, but it really isn’t round, it has more of an egg shape… or does it? No really. It does.
  • NASA claimed in 2002 the Moon was made out of cheese after discovering an expiration date printed on the Moon.  They released the following statement, “Using the new camera on the recently refitted Hubble Space Telescope, astronomers have been able to confirm that the Moon is made of green cheese. The telling clue was the resolution of a numeric date after which the Moon may go bad. Controversy still exists, however, over whether the date resolved is truly an expiration date or just a ‘sell by’ date.”  This, of course, was posted by NASA on April 1st… April Fools’ day.
  • While there is still some debate on how exactly the Moon formed, one of the most popular theories is that the Moon formed from a collision between the Earth and a planet-sized object about 4.6 billion years ago, called the “Big Whack”.  When the impact happened, a cloud of vaporized rock shot off the Earth’s surface and went into orbit around the Earth.  Over time, the cloud cooled and condensed into a ring of small, solid objects which then slowly gathered together, eventually forming the Moon.
  • The largest crater on the Moon is about 550 miles in diameter and is near the South Pole-Aitken Basin.  The impact caused by the asteroid that formed this crater was almost powerful enough to split the Moon into pieces.
  • The Moon used to have very active volcanoes.  The dark areas of the Moon, called maria (meaning “seas”), are cratered landscapes that were flooded with lava, which then froze forming smooth rock areas that resemble, from a distance, bodies of water on Earth.
  • The Moon has a surface area of about 14.6 million square miles, which is about 92.6% less surface area than the Earth has.  This is about 4 times the surface area of the United States.
  • The gravity on the Moon is about 17% what it is on the Earth.  So if you weigh 180 pounds on Earth, you will weigh about 30 pounds on the Moon.
  • If you ever landed on the Moon, you’d need to accelerate to 5,324 mph in order to escape the Moon’s gravitational pull.  This is about 21.3% the speed you’d need to reach to escape the Earth’s gravitational pull.
  • Jack Schmitt, an Apollo 17 astronaut, has the distinction of being the first known human to have extraterrestrial hay fever.  After returning to the lunar module and taking his helmet off, he had an instant reaction to the Moon dust with his nose stuffing up quickly.  This lasted a couple hours before going away.  According to Schmitt, he wasn’t the only one to experience this, but pilots don’t like to admit to any adverse symptoms or they think they’ll be grounded.  If you’re curious, several astronauts say that fresh Moon dust smells like spent gunpowder.
  • Another slightly popular “Moon myth” is that people can go temporarily crazy and/or that more criminal acts occur during full moons.   There have been numerous studies done to try to see if there is actually a link between the phases of the Moon and mental illness and the like, but, not surprisingly, to date nobody’s been able to find any such connection.
  • The word “lunatic” ultimately comes from the Latin for “moon”, “luna”, via the Old French “lunatique”, meaning “insane”.  It first popped up in English around the 13th century and referenced the above referenced mistaken belief that the Moon can make people crazy.
  • Yet another Moon myth is that during the 1950s and 1960s, Americans were all crazy about getting to the Moon.  In fact, according to Smithsonian space historian Roger Launius, during the early days of the Apollo program, the U.S. space program was one of the top government programs Americans listed that they thought should be dropped, with a full 60% of Americans feeling that the U.S. was spending too much money on space flight.
  • In 2002, a 72 year old Buzz Aldrin punched Bart Sibrel who is a “we never landed on the moon” conspiracy theorist, “documentary” maker, and cab driver.   Sibrel invited Aldrin to a hotel with Sibrel telling him he was making a children’s TV show on space.  Once Aldrin arrived at the hotel, Sibrel pulled out a Bible and tried to get Aldrin to put his hand on it and swear that he had walked on the Moon.  Needless to say, Aldrin was pretty irritated at this point.  Things got worse when Sibrel proceeded to call Aldrin a “liar” and a “coward”, at which point Aldrin punched him.  Lucky he didn’t also call him a poltroon, or Aldrin may have pulled a “President Andrew Jackson”, who once killed a man for calling him a “scoundrel, poltroon, and a coward”.
  • In 2009, Sibrel found himself in hot water once again while working as a cab driver.  Sibrel wanted a woman’s parking spot, but she refused to pull out of it, at which point Sibrel then was able to park across from the woman.  After parking, he proceeded to get out of his cab, hop onto the hood of the woman’s car, and jump up and down causing $1,400 worth of damage to the car.  It is possible Sibrel is one of those people who might think the Moon is made of cheese…
