If they are big enough (as for our everyday three spatial dimensions, if they are compactified too) even though a constant direction vector can be integrated to a closed loop through space, the fact that the Universe is expanding means that one cannot traverse this loop in a finite time. | |

| Nov 5, 2013 at 13:06 | comment | added | Luboš Motl | They're spatial dimensions - new temporal dimensions always lead to at least some problems if not inconsistencies - but otherwise they're the same kind of dimensions as the known ones, just with a different shape. To a creature much smaller than their shapes' size, they're exactly the same as the dimensions we know. The theory implies that the total number of spacetime dimensions is 10 or 11. We don't have "intuition" for higher-dimensional shapes because the extra dimensions are much smaller than the known ones but otherwise they'er intuitively exactly the same as the known spatial dimensions | |

change the tone of the question and add pop-sci tag
