Origin of space and time in a non-commutative cosmological model
A Friedman-like cosmological model, based on noncommutative geometry, is presented. Its Planck level is totally nonlocal with no space and no time. The dynamics on this level is strongly probabilistic which makes the initial singularity statistically insignificant. Space, time and the standard dynamics emerge when one goes from the non-commutative regime (on the Planck level) to the usual "commutative physics".

About the speaker
Michael Heller, Professor in the Faculty of Philosophy at the Pontifical Academy of Theology in Cracow, Poland, is a cosmologist and Catholic priest who has developed sharply focused and strikingly original concepts on the origin and cause of the universe. Heller's examination of fundamental questions such as "Does the universe need to have a cause?" engages a wide range of sources, in mathematics, philosophy, cosmology, and theology, allowing each field to share insights that may inform the others without any violence to their respective methodologies. With an academic and religious background that enables him to move comfortably and credibly within each of these domains, Heller has given new and important consideration to some of humankind's most profound concepts.
Heller's current work focuses on noncommutative geometry and groupoid theory in mathematics, which attempts to remove the problem of an initial cosmological singularity at the origin of the universe. "If on the fundamental level of physics there is no space and no time, as many physicists think," says Heller, "noncommutative geometry could be a
suitable tool to deal with such a situation."
In March 2008, Heller was awarded the $1.6 million USD (£820,000) Templeton Prize for his extensive philosophical and scientific probing of "big questions." His works have sought to reconcile the "known scientific world with the unknowable dimensions of God."
