Physics (Internal)

Simulating the Universe (an alternative approach)

This event is part of the Condensed Matter Theory Seminar Series.

What if the message of quantum mechanics is not abandoning determinism, but only discreetness, and what if space and time are truly granular on some tiny scale? What data structures and dynamics could possibly reflect a (or possibly the) Universe, if we know some large scale behviour, and we boldly assume that in principle it could run on a computer? In a highly bottom up approach I will tell what can one do in 3 weeks with these ideas, and how sparse undirected graphs and local replacement rules can give a framework for large scale physics. And of course I'll tell many-many open problems in the end.
