Extra spatial dimensions


A map of the cosmic microwave background made by NASA's WMAP satellite shows density fluctuations in the early universe – regions of higher density were slightly warmer than voids. Similar maps by Planck may reveal the existence and shape of extra spatial dimensions (Image: NASA/WMAP Science Team)
"Some theories – such as string theory – that attempt to unify all known forces into a single "theory of everything" posit the existence of extra spatial dimensions beyond the three familiar ones. [...] the detailed shape of those extra dimensions could be distinguished by Europe's Planck satellite, which is set to be launched in July 2008"
