The 'What If' Game

One of the better and more often used phrases in the English language is "what if". The "what if" is a staple in science fiction stories: "What if" the British had won the American Revolutionary War? "What if" that killer asteroid had missed the Earth 65 million years ago and the dinosaurs still was the top dog (as it were)? Or, "what if" antigravity existed? The possibilities are near endless. http://bit.ly/inx9x8
