Still can't sleep?  You must be feeling really tired about now, it's been two hours all ready.

Carl Sagan, btw, was one ugly dude  

Cannabis Consciousness;  that's hilarious  

Even the novice cannabis consumer has probably experienced a situation like this: you’re watching a movie and a friend makes a silly comment, and all of a sudden you just cannot stop laughing. By the time you finally can catch a breath, you may have even forgotten what you were laughing about in the first place. When you smoke weed, you’re more likely to laugh because you’re simply in a laughing mood. But once those giggles get going,  keeping coming is actually really good for you. We’re not kidding when we say that laughter is one of the best medicines.

I think it's inaccurate to say every ancient culture thought the earth was flat. The ancient Greeks, for example, did not. While I agree with you that many ancient cultures were observant of nature, you also have to admit that most of them did not have access to the mathematical tools needed to easily calculate the curvature of the earth, which is why many (if not all, I'm not sure) of the early demonstrations of curvature were done by the Greeks who developed Geometry as a mathematical discipline (at least in its "modern" form). I believe this is one of the earliest known proofs, done by a Greek mathematician using geometric tools. 

It's that idiot Eratosthenes in the 3rd century b.c., illustrated by the equally idiotic Carl Sagan in the 20th Century a.d., who tried to prove that The Earth was round and the stupid Greeks bought it.  I don't think the experiment proves a round earth.  You can replicate it yourself with a flashlight, two paper towel rolls and a dark room.  In other words, you get the same effect with a flat earth.  It's just that Sagan thinks that proves the earth is round;  i have no idea why, other than people have been saying that for a long time.
