Three Roads to Quantum Gravity
A leading theoretical physicist describes the search for a ''theory of everything''.
The Holy Grail of modern physics is the search for a ''quantum gravity'' view of the universe that unites Einstein''s general relativity with quantum theory. Until recently, these two foundational pillars of modern science have seemed incompatible: relativity deals exclusively with the universe at the large scale (...
