...origin of matter, energy and even space and time. The leading theory postulates that reality arises from infinitesimal "strings" wriggling in a hyperspace of 10 (or more) dimensions. Unfortunately, these hypothetical strings are so small that it would take a particle accelerator the size of the Milky Way to detect them! I am not alone in fearing that string theorists are not really practicing science anymore; one leading physicist has derided string theory as "medieval theology." Paul, here is persuasive evidence of science's plight...

But hints that ours is just one of many universes keep cropping up in all sorts of different theories--and in ways that can seem far stranger than fiction...
...inflate, that brief period of breakneck expansion should have left a telltale pattern imprinted on the radiation left over from the Big Bang, which still echoes around the universe in the form of electromagnetic microwaves. Two satellites set to be launched later this year are sensitive enough to detect such a pattern...
