Randall's maze 2

So why would be even bring such a crazy ideal up? We can only see 3 dimensions…why would there be more? Well why not? Why couldn’t there be more than 3 dimensions? Perhaps that could solve some of the weird problems we have in physics. And according to Randall, they do. There is one that I find fascinating that has to do with gravity. Have you ever thought about how weak gravity is? It’s really really weak. Even though you have the entire pull of the whole earth on you, you are still able to jump off the earth (it’s actually the electromagnetic force that allows you to do this). So in comparison to all the other forces gravity is really weak. Why is this? Randall and some of her colleagues say that it’s because the gravity is shared with the other dimensions. Fore some reason or another it’s stronger in those other dimensions than in ours and that’s why it seems so weak. Now, of course, that’s not all there is to her idea. There is a lot of super complicated math that I haven’t even looked into to go along with that general idea, but the point it extra dimensions are defiantly worth taking a look at.
