Consistent formulations of string theory require the existence of additional spatial dimensions. These extra dimensions can play a crucial role in determining the properties of our Universe, shedding new light on some of the greatest mysteries of nature, such as the observed weakness of gravity. If the extra dimensions are as large as the current observational limit at a sub-millimeter scale, they lead to an exciting possibility of testing string theory in the near-future collider experiments and in cosmology. I will discuss how such models emerge from string theory, showing why they are plausible and what are their experimental consequences and predictions.
