Now I may sound a little ignorant in my logic. Forgive me please, I’m only 14. But Since I have no idea how many acual dimentions there are I will simply have to state the 5 ones that humans exist in.  
There is the traditional highth, width and depth. Then there is the fourth dimention, time. WE move freely about in the first 3 dimentions. (Do I sound stupid yet?). In the 4th we move in a strait line. Time travellers at a rate of one second per second. Now the 5th demention is one we don’t move at all in. But we do exist in (Am I clear? This must seem painfully obvious to all you). This 5th dimention is probability, how likely things are to happen. Now I have NO idea how to wrap this up. So thank you for listening to me. What do you think about my theory?

You article being commented on is: [How many dimensions are there?](http://www.straightdope.com/mailbag/mdimensions.html)

Wolv, it’s a nice theory. The point is that “dimensions” are a model, they are used to help visualize and understand how the universe works. If using probability as a dimension works for your model, great. But there’s no right/wrong, and anyone is free to use any model they want that helps understand how things work. Physicists tend not to use “probability” as a dimensional point.
