Abstract
The last decade has seen an explosive revival of interest in extra spacetime dimensions. Inspired by developments in string theory, ingenious phenomenological models have been constructed in which gravity becomes strong at the scale of a few TeV, thereby solving the long-standing hierarchy problem of particle physics. Perhaps the most interesting aspect of these theories is the possibility of ‘seeing’ quantum gravity effects — including microscopic black holes — in experiments carried out at the TeV scale, of which the Large Hadron Collider (LHC) at CERN is the imminent one. Some of these ideas are reviewed in this article and the possibility of seeing signals for extra dimensions at the LHC are briefly discussed.
