If it only shines straight down, what gives you any clue as to what it might do if pointed elsewhere?
Here's my basic complaint against all this: Every single answer you guys give implies that we know little more now than was known 3,000 years ago. You poo-poo any and all science that demonstrates your error, yet you refuse to produce any proof through your own investigation.
To me, there are just three possibilities for your position:
1. You live some Amish-like existence that prevents you from seeking scientific knowledge.
2. You are dumber than sawdust.
3. You are all frauds and are just yanking everyone's chain for your own amusement (which I'd be okay with).
Whichever it is, you're at least providing some entertainment for the rest of the world.
