- Sheesh. Apparently most people are not even aware that you can cover the full
- moon with a dime held at arms length (this is smaller than your thumb).
- I suggest an experiment of direct observation with some pocket change to prove
- this to yourself tonight if you are unbelieving. No, gloves are optional.
-
- There are psychological reasons why the moon SEEMS to be larger than a dime
- --it's a bright object against a dark background, when seen near the horizon
- it's near similar sized distant objects known to be large, etc. Even
- Aristotle wrote about this common optical illusion and why the
- moon seems larger than it's true size, so people have been amazed by this
- illusion for some time. It also makes a good bar bet.
-
- Once you have observed for yourself the dime covering the moon experiment,
- the original statement becomes much more plausable.
