This seriously cracked me up. Read it, it even has "physics of a flat earth".

At first, I was like "Lol"
Then I was like "I see..."
Then it was all "Prove them wrong..."

I mean, seriously.
There's a theory that the univers is contained within the earth. And it's impossible to disprove at present time.

Theory is this, since people will just start screaming "NO U STUPID RETARD EARTH BE ROUNDZ LOL"
The universe is like a basketball, i's all contained inside it. Our earth i on the inner surface of the basketball, and as you travel away fromt he edge, time slows and distances shrink. Thus, the universe is still infinite.
This theory also dictates, that cutting a hole through the earths crust all the way to the core is the only way to disprove it. And they're right. Unfortunately, if the theory is correct, doing so would kind of cause the universe to "gush out" like air would. Thus ending existance

Well, I've been converted.

Anyway I've heard of this before although have never looked it up. The physics are undeniable.

ps, check out the "hollow earth" related link.

They should probably take a trip around the world

Show me this big ice wall.
Though the universe is inside the earth sounds cool and almost believable, it doesn't really make too much sense.

I don't know whether you're being sarcastic or not.

I feel bad for the people in that society.

I don't. They're having the time of their lives, actually being taken seriously.

The earth does not exist.

What we are living in is just an illusion. We are all just puppets in someone's game.

We are all living in the Matrix. Unfortunately nobody has offered any red pills...

I've been offered one from a hobo in the subway. I just ran. I like being inside the Matrix.

LEZ STRT T3H NO EART SOSAITEE!

But yeah, it's fake. And pretty much everyone has heard of it (even my grandpa).
