  A fundamental problem of Einstein's theory of classical general relativity is
the existence of singularities such as the big bang. All known laws of physics
end at these boundaries of classical space-time. Thanks to recent developments
in quantum gravity, supercomputers are now playing an important role in
understanding the resolution of big bang and black hole singularities. Using
supercomputers, explorations of the very genesis of space and time from quantum
geometry are revealing a novel picture of what lies beyond classical
singularities and the new physics of the birth of our universe.
