Kurt Gödel's legacy—Time travel is mathematically imaginable.

"Does Future Lie in the Past?" This is the title of an international conference in Vienna that combines logic, computer science and physics featuring speakers such as Nobel laureate Rainer Weiss, mathematical rockstar John D. Barrow, AI researcher Toby Walsh, and physicist Marika Taylor among others.
Two events that have strongly influenced the world of science are celebrating an anniversary this year: The decisive review of Albert Einstein's theory of relativity is 100 years old. And 70 years ago Kurt Gödel proved that the theory of relativity permits a strange kind of universe: Under certain conditions, as Gödel could show, a universe with closed world lines is possible, in which time has a circular structure and objects at some point seamlessly return to their own past. Thus time travel within the general theory of relativity is conceivable...

Artificial Intelligence and Quantum Mechanics
Matthias Baaz, TU Vienna: "Just as Einstein and Gödel shook the foundations of science, today's knowledge about statistical and logical methods could lead the way to artificial intelligence (AI) in new directions". AI researcher Toby Walsh and science philosopher Reinhard Kahle are investigating developments in artificial intelligence and the demand for explainable and responsible AI computers that can learn independently without corrupt or distorted data. Another future topic with potential for revolutionary insights is quantum informatics: quantum physicists Markus Aspelmeyer and Wolfgang Schleich as well as mathematician and physicist Marika Taylor, formerly a close collaborator of Stephen Hawking, will describe the current state of research in this field.
