I'm sure there's some perfectly good explanation for "Gravity on the island", but I don't know what it is.

My best guess was that its a reference to the island in the tv show Lost, but I fail to see why that would be different from the gravity on earth.

I think it's related to "4, 8, 15, 16, 23, 42", the numbers in Lost
