Black Holes and Extra Dimensions
Dec. 7, 2004
Of the four known forces -- gravity, electromagnetism, and the weak and
strong forces -- gravity is by far the weakest. The weakness of gravity
may not be an intrinsic property, however, but may result from the dilution
of gravity in extra spatial dimensions. Diverse experiments, ranging from
tabletop probes of Newtonian gravity to km-scale cosmic ray detectors, are
now putting this possibility to the test. I will give an overview of extra
dimensions with an emphasis on one of its most tantalizing predictions ---
the production of microscopic black holes in high energy particle
collisions.
