You've been transported back in time to Miletus, an ancient Greek city. It is 600BCE.

All of a sudden, this chap Ishygddamese runs up to you and shouts "Hey! I can prove the Sun must be way closer to the Earth than the Moon!"

"Look at this torch. When it's further away from you, it's dimmer, right? And when I'm much closer to you, it's brighter! ALL CLOSER LIGHTS ARE ALWAYS BRIGHTER! And the Sun is much brighter than the Moon, so it's closer!"

You sigh. "Yes, yes, Ishygddamese. But...."

How would you explain that he is wrong? Counterexamples are acceptable - this is Ancient Greece, after all.

Further thought experiments as time goes on.

Take him to a dark room. Light up the torch in the center of the room. Now take a small rock and then carry it around you while you spin around the torch to show how the world spins and how the sun is at the center. Not only that, to show the effects of sun on the moon

yeah they were a big deal, but they were only predicted based on patterns, not calculations of orbits or anything like that

>> No.5089638

You could try to teach people about orbits, and wait for the next eclipse to show them that the dark spot in the sun is about the size of the moon. While it wouldn't prove the moon is blocking out the sun, it would definitely suggest it.
The only problem with doing it this way is you might get sentenced to death for conflicting with the Greek religion. Speaking ill of the gods and what not.

>> No.5089655

It's relatively simple, I think. Place a bright torch some meters away from him in a dark room, but don't tell him where it is. Place another torch, which is noticeably dimmer than the previous(i.e., the flame is moments from dying out) a few meters away, as well, but closer to him than the previous.

I'd explain that, by his theory, the torch which is brighter must be closer. However, after taking a few steps with him, he'd be able to see that the dimmer torch is, in actuality, the one closest to him.

In other words, brightness doesn't automatically mean closer.

>> No.5089663

not OP, but I think this is probably the easiest answer without getting your head lopped off - anyone can see embers are dimmer than a flame.

>> No.5089664

>>5089655
He's just going to make some argument about the sun and the moon being of the same kind or of the same substance and thus the only thing that could differ between them is their distance or some such thing. If you actually believe that he went into his argument not realizing that there are more influences on brightness than simple distance you're an idiot.

if he really did believe that the sun and the moon are the same thing, I would say that the sun does not have phases, the sun does not have patterns, and the sun emits a light of different nature than the moon.

I would get a bright light and put it 10 feet away from him, then get a very dim light and put it 1 foot away from him. Then I would say that the bright light that is 10ft away is closer to him in a mocking voice.
