Resumen de Why does space have three dimensions?
Webb talks about the string theory. One of string theory's peculiar features is that when applied to fewer than nine spatial dimensions, the mathematics goes wild, predicting violent fluctuations that rip apart the very fabric of the universe. But extra dimensions do more than just save string theory's blushes. In a wider set of theories, gravity leaking into a higher space could explain why in the three dimensions it is so weak compared with the other fundamental forces, and why the expansion of the universe is apparently accelerating
