    "abstract": "Our universe appears to have been created not out of nothing but from a\nstrange space-time dust. Quantum geometry (loop quantum gravity) makes it\npossible to avoid the ominous beginning of our universe with its physically\nunrealistic (i.e. infinite) curvature, extreme temperature, and energy density.\nThis could be the long sought after explanation of the big-bang and perhaps\neven opens a window into a time before the big-bang: Space itself may have come\nfrom an earlier collapsing universe that turned inside out or inverted and\nbegan to expand again. - Key words: Loop quantum cosmology, Wheeler-DeWitt\nequation, singularity, Abhay Ashtekar, Martin Bojowald.",
