Two events that have had a strong influence on the world of science are celebrating an anniversary this year: the decisive review of Albert Einstein's theory of relativity is 100 years old. Furthermore, 70 years ago Kurt Gödel proved that theory of relativity is compatible with closed time lines. In this Gödel's rotating universe, time travel is at least mathematically imaginable. For this reason, the Kurt Gödel Society is organizing the international conference "Kurt Gödel´s Legacy: Does Future Lie in The Past?" at the University of Vienna from July 25 to 27, 2019.
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.
Einstein, commenting on what now is known as the Gödel Universe, remarked about the possible existence of causality violating curves that “This problem had already bothered me when constructing the theory without being able to come to clear conclusions”.
⌛Mapping the Truth: Keynote Speakers
From Gödel's Incompleteness Theorem, we know that some truths are unprovable, and some nontruths are un-disprovable within a given formal system. To map the way to the truth the conference brings together some of the most important and prominent researchers in the fields of Physics, Mathematics, Philosophy, Logic, and Artificial Intelligence in the world.
- Markus Aspelmeyer, Physics, University of Vienna
- John D.Barrow, Cosmology, Theoretical physics, and Mathematics, Grasham College
- Charles L. Bennett, Physics and Astronomy, Johns Hopkins University
- David Bennett, NASA Goddard Space Flight Center and University of Maryland
- George F.R. Ellis, Mathematics and Complex systems, University of Cape Town
- Juliet Floyd, Philosophy, Boston University
- Thomas Henzinger, Computer science, IST Austria
- Reinhard Kahle, Philosophy and History of science, Universität Tübingen
- Jan von Plato, Logic, University of Helsinki

The conference will take place between July 25-27, 2019.
"Gödel's Legacy: Does future lie in the past?" will take place at the University of Vienna, Universität Wien (Universitätsring 1, 1010 Vienna) in the Main Ceremonial Chamber.
