Abstract:
Understanding the physics of very early Universe requires a consistent framework merging the core components of general relativity (GR) and quantum physics -- a theory of quantum gravity. One of attempts of constructing such merge is Loop Quantum Gravity (LQG) -- a quantization of GR strictly adhering to the so called background independence and employing a nonstandard (distinct from Schroedinger) quantum representation. I will briefly introduce main principles, features and results of LQG and its symmetry reduced (cosmological) version -- Loop Quantum Cosmology. The latter framework in particular permitted making unambiguous prediction of early Universe dynamics, leading to a picture qualitatively differing from standard big bang paradigm.
