Just a quick one for you today, folks.

By now people are used to the idea that we need four dimensions to describe the universe: length, breadth and depth providing information about space, and a fourth dimension, time. But in the world of really high-level theoretical physics, people are finding that four dimensions are just not enough to give the full picture. You often hear physicists talking about numbers of dimensions that are just plain silly. Why? Isn’t four enough for them?

Here is a lovely video in two parts that gives an interesting explanation. In order to describe the world fully ­– really­ fully ­– we need to use ten-dimensional space. Make yourself a nice cup of tea, and enjoy.
