04. How many dimensions are there in space? (A K2S Question)

From The Space Library

We commonly experience three dimensions of space and a fourth dimension that we know as time. It is possible that there are an infinite number of dimensions in space. Some new ideas, called string theory, describe the structure of atoms and the Universe using thirteen dimensions! How can there be more dimensions than we experience every day? Some dimensions are apparently folded up so that we do not know that they are present. If you find this is hard to imagine, you are not alone. Even the people who thought of string theory cannot picture thirteen dimensions. But trying to describe those dimensions using mathematics has led to some promising ideas that can describe both gravity and how atoms are put together. This is something that no single physical theory can currently do.
