If world is three dimensional, how is general relativity true? |

Answer» Explanation: The scientists propose that space is 3D because of a THERMODYNAMIC quantity called the Helmholtz FREE energy density. In a UNIVERSE filled with RADIATION, this density can be thought of as a kind of pressure on all of space, which depends on the universe's temperature and its number of SPATIAL dimensions. |
