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

In 1949, Kurt Goedel 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 Goedel 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?.

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 chronology protection 
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 Geodel?s philosophical ideas on the existence of time, a subject 
that he intensively discussed with Einstein in Princetown. ?In my view Kurt 
Goedel?s papers represent an important contribution to general relativity, 
especially his analysis of the concept of time.? said Einstein.

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 a conference at the University 
of Vienna, Austria. This event will bring together the prominent researchers 
from the fields of Physics, Mathematics, Philosophy and Artificial 
Intelligence.



The conference will be enhanced with a special exhibition about life and

work of Kurt Goedel with emphasis on the Goedel's solution.
