quantum field theory
CERN's Large Hadron Collider is one of the few scientific experiments to sparked wide-spread media coverage, particularly with the 2012 announcement of the discovery of the long-sought Higgs boson. So what really goes on at CERN and why the hubbub about the Large Hadron Collider, known as the LHC?
In 2004 Stephen Hawking famously conceded that black holes do not devour all information when they swallow matter — seemingly resolving the black hole information paradox that had perplexed physicists for decades. But some argue that the paradox remains open and we must abandon our simple picture of spacetime to unravel it.
By the 1970s physicists had successfully tamed three of the fundamental forces using a sophisticated construct called quantum field theory. The trouble was that the framework seemed to fall apart when you looked at very high or very low energy scales. So how could these be thought of as valid theories? It's a question physicists are still grappling with today.
