# Kurt Goedel’s Legacy: Does Future lie in the Past?

DATE: | Thursday, July 25, 2019 – Saturday, July 27, 2019 |

VENUE: | University of Vienna |

The Kurt Goedel Society intends to celebrate the 70th anniversary of Goedel’s seminal publication and the 100th anniversary of the decisive experimental verification of general relativity by organizing an international conference **Kurt Goedel’s Legacy:** Does Future lie in the Past? The conference will take place between July 25-27, 2019 at University of Vienna. This event should bring together the prominent researchers from the fields of Physics, Mathematics, Philosophy and Artificial Intelligence.

# Gödel’s solutions to Einstein’s relativity equations and their consequences

Still today, there is an ongoing debate on how physical such solutions are and whether general relativity would prevent the formation of regions where causality violation is possible, e.g. S.Hawking’s proposal of a “chronology protections conjecture”. Some physicists speculate that closed time curves might be ruled out by a future theory of quantum gravity which would replace general relativity and there are many other attempts to overcome that problem. Closely related are Gödel’s philosophical ideas on the existence of time, a subject that he intensively discussed with Einstein in Princetown. “In my view Kurt Gödel’s papers represent an important contribution to general relativity, especially his analysis of the concept time.” said Einstein. In 1949, Kurt Gödel showed that there exist solutions to Einstein’s equations of general relativity allowing for closed timelike curves. A closed timelike curve is a world line (in space and time) along which a material particle can travel returning to its spacetime starting point. The existence of such curves would allow time travel into one’s own past leading to all kind of causality paradoxes. The conference will be enhanced with a special exhibition about life and work of Kurt Gödel with emphasis on the Gödel’s solution.

# Kurt Gödel Society

The Kurt Gödel Society was founded in 1987 and is chartered in Vienna. It is an international organization for the promotion of research in the areas of Logic, Philosophy, History of Mathematics, above all in connection with the biography of Kurt Gödel, and in other areas to which Gödel made contributions, especially mathematics, physics, theology, philosophy and Leibniz studies.
