RationalWiki's 2018 Fundraiser

There is no RationalWiki without you. We are a small non-profit with no staff — we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.

If everyone seeing this today donates $5, we will meet our goal for 2018.

Fighting pseudoscience isn't free.

Proof the moon belongs to Rational Wiki.[citation NOT needed]

A moon is a natural satellite orbiting a planet. The Earth's only moon is known rather unimaginatively as "the Moon" (or sometimes Luna if you're feeling fancy.) Being the most noticeable object in the night sky, it is a subject of much woo, particularly in astrology where it is usually given a female quality and a high degree of importance in the sky.

Creationism[edit]

See the main articles on this topic: Evidence against a recent creation and Creationist claims

Creationists argue that the moon proves young Earth. In a word, no. It's not, although it's been touted as one.

The Moon has been a source of astronomical study for at least three millennia. To say that science has failed to explain key elements of lunar motion, geography, or composition, is to be willfully blind. Nonetheless, many creationists fabricate "errors" in scientific studies of the Moon, and suggest that, since science has failed, the only alternative is creationism. This is gap-filling with God to an absurd degree. Assuming, for once, that science could not explain the Moon, this does not imply that the only explanation is God. Science evolves. Not everything is known now, nor should science be forced to prove the universe to disprove creationism. The standard for evaluating creationist claims about scientific disciplines is the same that applies to all scientific theories: does the claim match the evidence? Regarding creationism, the answer is a resounding, "no!"

Creationist claims surrounding the moon:

Moon landings and the idiots that claim they are a hoax[edit]

See the main article on this topic: Moon landing hoax

Twelve American astronauts landed on the Moon between 1969 and 1972, took pictures, left behind some junk, and came back home with some rocks. Deal with it.

The moon gives off light[edit]

It seems natural enough for pre-scientific cultures to assume that the sun and the moon both give off light. However, this is not true; the moon is a reflector of light, not a generator, save as a black body, and in that sense, everything gives off light. A good example of this is Genesis 1:16, in which god creates "a greater light to rule the day" (the sun) and "a lesser light to rule the night" (the moon). So there goes any claim that Genesis is scientific.

Bill Nye the Science Guy took the bible to task on this one. It wasn't popular.

Muhammad: Moon-Smasher[edit]

According to the Qur'an, Muhammad broke the Moon. Yes, really. This is a real piece of silliness that basically renders any claim that the Qur'an is science to be utter bullshit. It's total fantasy.

Nevertheless, some truly dedicated followers of the "TEH QUR'AN IS TOTES SCIENCE" argument have still tried to prove it. A few of them stoop to using an article proposing that NASA found a crack that ran all the way around the Moon -- this argument is a total fraud, as anyone with a non-Qur'an-addled brain can spot.

Many Islamic scholars believe that this verse is best understood as a statement of something to occur at the final judgment. This is supported by the fact that the Surah concerns itself with that judgement, and the references to previous judgements are in the middle part of the Surah, and also that the immediate context of the verse makes a future rather than past interpretation more likely. While there is weak support in the Sunnah for a literal past tense interpretation of the event, even in that case, a plausible interpretation would include the possibility of e.g. a large asteroid impact providing the appearance of the Moon splitting (contemporary writings from India record one such event). It should also be noted that the writing here is poetic, so what exactly "the Moon is cleft asunder" indicates is uncertain and based on the Arabic is just as likely to have a metaphorical meaning. In other words, there is no single interpretation of what exactly this verse refers to. If taken literally it refers to some obvious sign in the moon, figuratively it would likely refer to Islam "tearing assunder" the religious fabric of the Middle East (if past tense) or the world (if end times was meant).

Other Muslim apologetics claim that, when Muhammad put the Moon back together, there was no crack because it was joined together perfectly, molecule-to-molecule. This is special pleading on a grand scale and should be ignored.

Apparent size and the idiots that claim Aliensdidit[edit]

It is a fact that the geometry of the Earth-Moon-Sun system is such that the apparent sizes of the Sun and the Moon, as seen from here, are very close to the same. During a total solar eclipse it is often the case that the Moon sits right on top of the Sun like two stacked pennies (not always, however — sometimes the Moon is at perigee and an annular eclipse is the result. Like a US quarter (24.26mm) stacked on a UK 2p (25.9mm).)[note 2]

Astronomers tend to just accept this as a fact of nature. Pseudoastronomers, when lecturing to, say, MUFON interest groups, are likely to cue up the Powerpoint™ slide and say "Can this be coincidence? I THINK NOT!" The extremist pseudoastronomical position is that the Moon is obviously artificial, towed carefully into place by Aliens.

Moon cheese![edit]

The moon is quite definitely made of cheese. Wallace and Gromit proved it.

Notes[edit]

  1. Pictured here is the near side, which faces Earth constantly and is completely visible during a full moon. The far side doesn't have nearly as much of the darker spots that the "man in the moon" is made of so it's more pale and boring.
  2. If you want to get all accurate about it, here are the numbers:
    Moon -- 29.3 minutes of arc at apogee, 34.1 at perigee
    Sun -- 31.6 at Earth's aphelion, 32.7 at perihelion
    So it can also happen that the Moon appears too big to stack on the Sun
