Nope. There is always a possibility for anything sir. Anything that is Probable must by definition be Possible; However, not everything that is Possible is going to be Probable. Ever heard of the Infinite Monkey Theorem? Here's a little explanation compliments of Google. [spoiler] The infinite monkey theorem states that a monkey hitting keys at random on a typewriter keyboard for an infinite amount of time will almost surely type a given text, such as the complete works of William Shakespeare. The probability of a universe full of monkeys typing a complete work such as Shakespeare's Hamlet is so tiny that the chance of it occurring during a period of time hundreds of thousands of orders of magnitude longer than the age of the universe is extremely low (but technically not zero). There is less than a one in a trillion chance of success that such a universe made of monkeys could type any particular document a mere 79 characters long. [/spoiler]
