Description
One of the key predictions of loop quantum gravity is that classical
differential geometry of GR is replaced by a discrete quantum
geometry at the Planck scale. In this talk we will discuss the way
numerical simulations of quantum spacetime is far more challenging
than the ones in classical spacetime. We will then discuss some novel
procedures to overcome these challenges and discuss various
numerical results. These results show that big bang singularity in
isotropic and anistropic spacetimes are resolved and that prove
validity of an effective spacetime description. The latter has been
extensively used to understand new physics at the Planck scale and
signatures in cosmic microwave background.
