Inner space: If this array of vine-like cables and twinkling lights seems strange, its interior workings are even more elusive. In the lab of physics professor Stephen Reucroft, who studies what happens when subatomic particles are smashed together-where the particles go and how much energy they give off-this instrumentation carries the noise of the energy pulses given off by the collisions and separates them from background static. That pervasive static is hypothesized to be energy lingering from the Big Bang, the formation of the universe.
