Stop
the Lunacy! 5 Mad Myths About the Moon
By Stephanie

The full
moon of March 2011, as …
The
biggest full moon of the year will rise Saturday (May 5) as Earth's only
satellite swings into its perigee, or closest approach to Earth. This so-called
"supermoon" will appear extra big and extra bright.
In honor of the moon's big show, we're dispelling a few myths about the Earth's rocky
satellite. Read on for the real scoop on the moon's role in madness, the
history of the moon landing, and how that whole green cheese thing got started.
Myth 1: The Moon Makes Us Crazy
The word
lunacy traces its roots to the word "lunar," and plenty of people,
from nurses to police officers, will tell you that things get wild around the
full moon.
But this non-supernatural equivalent of the werewolf myth
doesn't hold water. A 1985 review of the literature on the timing of mental
illness and the moon found that the folklore
that links the full moon with mental breakdowns, criminal behavior and other
disturbances has no basis in scientific data. Nor has research turned up a link
between the moon's phase and surgery
outcomes — though pets are more likely to
need a trip to the emergency
room during a full moon, likely because owners
keep them out and about later on nights when the moon brightens up the sky.
Myth 2: The Supermoon Can Cause Disasters
The
reason we have supermoons is because the moon's orbit is not perfectly
circular. When it swings closer to Earth on its elliptical path, the moon does
exert a bit more of a gravitational pull on our planet. But it's nothing Earth
can't handle.
Tidal forces around the world will be particularly high and
low, with the moon exerting 42 percent more force at its closest point to Earth
than it does at its farthest, according to
Joe Rao, SPACE.com's skywatching columnist. This
extra force doesn't have an appreciable effect on disasters such as earthquakes
and tsunamis, however.
"A lot of studies have been done on this kind of thing
by USGS scientists and others," John Bellini, a geophysicist at the U.S.
Geological Survey told LiveScience's sister site Life's
Little Mysteries. "They haven't found
anything significant at all."
Myth 3: The Moon Landing Was a Hoax
We've got video. We've got rocks. We've got a dozen
astronauts who have proudly returned to Earth to recall walking on our great
satellite. But conspiracy theories claiming that the moon landing was faked
just won't die.
These moon hoax
theories are multitudinous and varied,
ranging from claims that there was no dust on the Apollo 11 Lander footpads so
the Lander must have never left a secret soundstage (In fact, dust on the moon
doesn't hang in the air as it does on Earth due to a lack of gravity, so dust
kicked up by the landing would have been hurled away from the Lander) to
theories about faked rock specimens (In reality, moon rocks have been
researched by NASA scientists and independent researchers alike. They're unlike
any Earth rocks, lacking water-bearing minerals and bearing tiny meteoroid
craters from the specks of dust that would have been burned up in Earth's
atmosphere but which landed on the surface of the airless moon.)
As
thinly sourced as it is, the hoax theories can be frustrating to those who
risked their lives to get to the moon. In 2002, Buzz Aldrin, one of the members
of the original 1969 Apollo 11 mission, was dogged by conspiracy theorist Bart
Sibrel at an event. When Sibrel blocked Aldrin's path and called him a
"coward" and a "liar," the then-72-year-old astronaut
punched Sibrel in the face.
Myth 4: The Moon Is Made of Green Cheese
The myth to dispel here isn't so much about the moon's
makeup — definitely not cheese — but rather the idea that anyone ever believed
the old "the moon is green cheese" canard at all. In fact, the cheese
myth seemed to have started with a sardonic little couplet by English poet John
Heywood (1497-1580), who wrote, "Ye set circumquaques to make me beleue/ Or thinke, that the moone
is made of gréene chéese."
In other
words, the first known mention of the moon being green cheese was actually
mocking the idea that anyone would believe that the moon was green cheese.
Heywood apparently underestimated early 20th-century children: A 1902 study
published in the American Journal of Psychology surveyed young children about
their beliefs about the moon and found that the most common explanation for
what it might be made of was cheese. Other theories included rags, God, yellow
paper and "dead people who join hands in a circle of light."
Myth 5: Cold War-Era America Was Moon-Crazy
Today, Americans remember the 1950s and 1960s-era space
race as a time when NASA had broad public support. In fact, levels of support
for human
lunar exploration were close to what is seen
today.
During
NASA's Apollo program, 45 percent to 60 percent of Americans believed the U.S.
was spending too much money on spaceflight, according to a 2003 paper published
in the journal Space Policy. Polls in the 1960s ranked spaceflight near the top
of the list of programs that Americans wanted cut, study researcher and
Smithsonian space historian Roger Launius found.
"[T]he
public was never enthusiastic about human lunar exploration, and especially
about the costs associated with it," Launius wrote. The enthusiasm it had
"waned over time," he continued, "until by the end of the Apollo
program in December 1972 one has the image of the program as something akin to
a limping marathoner straining with every muscle to reach the finish line
before collapsing."
