  GENERAL relativity and quantum the-
  ory have profoundly changed our view
  of the world. Furthermore, both theo-
  ries have been veriﬁed to extraordinary
  accuracy in the last several decades.
  Loop quantum gravity takes this novel
  view of the world seriously, by incorpo-
  rating the notions of space and time
  from general relativity directly into
  quantum ﬁeld theory. The theory that
  results is radically different from con-
  ventional quantum ﬁeld theory. Not
  only does it provide a precise mathemat-
  ical picture of quantum space and time,
  but it also offers a solution to long-stand-
  ing problems such as the thermodynam-
  ics of black holes and the physics of the
  Big Bang.
  The most appealing aspect of loop
  quantum gravity is that it predicts that
  space is not inﬁnitely divisible, but that it
  has a granular structure. The size of
  these elementary “quanta of space” can
  be computed explicitly within the the-
  ory, in an an
