Simple way to explain it to people not smart enough to get the scientist`s explanation:
Set a ball and a lamp in an otherwise dark room. Walk around the ball to see the shadow/light sides. You only see the entire ball when you are looking at it from an angle close to the light source. Same phenomenon you learn in art class when you start learning light and shadows.

"I learned this in school forty five years ago when this country still had a learning curriculum."

@SarahofBorg: I`m afraid you`ve got it wrong yourself. A full moon ALWAYS rises at approximately sunset (give or take an hour) and sets at sunrise (give or take an hour). It`s opposite the sun in the sky, which is why it`s full. Similarly, a new moon ALWAYS rises at approximately sunrise and sets at dawn. And the first quarter phase rises at approximately midday, while the last quarter phase rises at approximately midnight.

A corollary to the above is that a lunar eclipse always occurs during a full moon. This is because the Earth`s shadow is falling on the Moon, which means (of course) that the Moon and Sun are opposite each other in the sky relative to Earth.

And for anyone still following this discussion, Yes, I recalled the above without Googling any of it. I still remember my elementary schoolteacher illustrating all of this in a dark classroom with a globe, an orange, and a flashlight.

Also, having now watched the video: anyone who was dumb enough to not understand lunar phases sure as hell didn`t understand the second half of the video where he explains how to detect life on other planets.

That`s nothing. I think most people don`t realize that the moon rises and sets in a rotating cycle so that it can rise or set at absolutely any time of day. A full moon can rise at 2pm and set at 12AM. Most people seem to think it rises when the sun goes down.

It`s common in Australia, where that was filmed, at the very least.

I don`t actually know anyone who follows astrology, just figured they would know this with all the moon and star worship or whatever it is.

But yeah, normal people don`t give a frak about the reflection on the moon. I forget everyone on the internet has an IQ of 190, a penis of at least 10 inches, and makes a minimum of 100k a year...

For those of you with your 190 IQ, the earth`s shadow IS the common answer.

Astrological groups rarely know anything about astronomy. Or, indeed, about astrology.

Next time a believer bothers you, try this: Ask them what school of astrology they follow and whether or not they account for precession. Extremely basic stuff and absolutely essential to even pretending that astrology makes sense, but I haven`t yet met one who even understands the questions, let alone has any answers.

Common everywhere. Amongst the people I know, I`d be very surprised if more than a quarter of them would know the right answer. I wouldn`t be surprised if only a couple of people did. I wasn`t sure myself.

It`s not a stupid answer, merely an ignorant one. The phases of the moon do resemble different degrees of eclipse (or lack of eclipse). The moon does orbit the Earth in the same period of time, so it is not stupid to think that the Earth casts regularly varying amounts of shadow on the moon, causing the phases of the moon.

It`s a wrong answer, but it`s not a stupid one.

I`ve NEVER heard someone say it was the Earth`s shadow for the phases

Seriously, anyone defending these people`s ignorance are, in my mind, absolutely drating moronic. You lack the basic human curiosity that has allowed our world to get to where we are now (I hate our world and what it`s become, I want the 50`s back)

Ugh. This is astronomy 101 stuff and it`s shocking how much people don`t know or care about the basics of OUR solar system.

And if you thought their answers were bad, trying asking basic astronomy questions to my family. Oh boy.

@OldOllie and Davy: Let me join your club of dismay over this. Call me elitist or whatever you want, but I can`t see how anyone could make it through junior high school, let alone high school, and not understand the phases of the Moon. I mean, really.
