It's tempting to think of the universe as a meaningless repository for celestial objects like planets and stars. But an intriguing theory suggests there's much more to the cosmos than meets the eye — and that black holes play an integral role in what our universe is actually trying to achieve.
The more we learn about the universe, the more we discover just how diverse all its planets, stars, nebulae and unexplained chunks of matter really are. So what is all this matter doing in our universe, other than just floating in space?
Particle physics is to physics what big game hunting is to field biology. While theoretical physicists pore over their mathematical models, particle physicists are out in the brush with their pith helmets and shotguns, speaking softly, carrying big accelerators and blowing stuff up real good.
