"From the Ted Talk by Brian Greene: Making sense of string theory"

#### Unscramble the Blue Letters

Now, does string theory offer an answer? Not yet. But we believe the answer for why those numbers have the values they do may rely on the form of the extra dimensions. And the wonderful thing is, if those numbers had any other vaelus than the known ones, the urnveise, as we know it, wouldn't exist. This is a deep question. Why are those numbers so finely tuned to allow stars to shine and planets to form, when we rezgoncie that if you fiddle with those numbers â if I had 20 dials up here and I let you come up and fiddle with those numbers, almost any fiddling makes the universe disappear. So can we explain those 20 nbmuers? And srntig theory suggests that those 20 numbers have to do with the extra deinomsins. Let me show you how. So when we talk about the extra dimensions in string theory, it's not one etxra dimension, as in the older ideas of Kaluza and Klein. This is what string theory says about the extra dimensions. They have a very rich, intertwined geometry.

Now, does string theory offer an answer? Not yet. But we believe the answer for why those numbers have the values they do may rely on the form of the extra dimensions. And the wonderful thing is, if those numbers had any other values than the known ones, the universe, as we know it, wouldn't exist. This is a deep question. Why are those numbers so finely tuned to allow stars to shine and planets to form, when we recognize that if you fiddle with those numbers â if I had 20 dials up here and I let you come up and fiddle with those numbers, almost any fiddling makes the universe disappear. So can we explain those 20 numbers? And string theory suggests that those 20 numbers have to do with the extra dimensions. Let me show you how.
