Anyway one day while listening to these books. I realized C. S. Lewis was talking about the theory of relativity in his books. You know how time moves at different speeds in our world and Narnia, but when we where in Narnia and our world we don't notice the difference. Why? Because of the theory of relativity.
Time always seems to move at a "normal" pace, no matter how fast or slow it is actually moving. Time in Narnia moves faster than time in our world, this has been proven throughout the books. But when we are in Narnia it seems to move at the same pace as in our world, because time moves relative to us. I have not studied the theory of relativity in any great depth, I do know a little about it, and understand enough to see that it is used in Narnia.
I am probably very poorly explained it to you, but I hope you can get an idea of what I am saying. :)
