Dear all,

this Thursday 28 of January at 3pm GMT (10am Toronto, 4pm Vienna, 11pm Hong Kong) we will have a QISS Virtual Seminar by Lee Smolin.

Zoom link https://hku.zoom.us/j/728065144  https://hku.zoom.us/j/728065144 or live at youtube.com/c/QISSproject https://youtube.com/c/QISSproject.

Title: The quantum universe as a collection of partial views of itself. Abstract: I describe a recent proposal for a simultaneous completion of quantum mechanics and general relativity, called the causal theory of views (CTV). Among its postulates are that time, in the sense of causal relations amongst events, is fundamental, and that space is emergent-along with everything that depends on space, such as distances, derivatives, fields, locality, non-locality etc. Also assumed real and fundamental are energy and momentum. Each event than has a view of the rest of the universe, which is made by the energy and momentum transferred to it by its causal precedents. To define dynamics we must introduce a measure of distance on the space of views. The idea is that differences of views substitutes for spacial distances and derivatives. The potential energy is then postulated to be a measure of the total diversity of views in the universe, called the variety. The kinetic energy is then related to the variety’s rate of change under causal evolution. The dynamics is defined by a sum over causal histories, from which space and spacetime emerge at the semiclassical approximation. N body nonrelativistic quantum mechanics is also derived, due to the variety reducing to Bohm’s quantum potential. Further steps are sketched.

QISS Virtual Seminars General Info

The idea Seminar topics range from fundamental theory to experiments and the philosophy of science, in particular on questions at the intersection of Quantum Gravity, Quantum Information and Quantum Foundations. The goal is to stimulate discussion across disciplines. The presentation is short (<30 mins) and speakers are encouraged to make it pedagogical. A commentator first engages the speaker(s) for ~10mins to get the discussion going. After this stage, questions and comments are open to all participants for one hour and twenty minutes. The total duration of the seminar is two hours.

How to join the seminar To join the seminar via Zoom first download Zoom Client for Meetings https://zoom.us/download.
