The Time Machine Factory [unspeakable, speakable] on Time Travel - TMF2024

In line with previous editions, the Time Machine Factory [unspeakable, speakable] on Time Travel - 2024 conference focuses on causality and non-locality in physics,  and the insurgence of situations where causality or chronology can potentially be violated, and how this relates to the existence of “time machines”.

The conference has the following aims

• Revive the interest in studying time travel, which poses new mathematical challenges and could not be ruled out by physics
• Study the role of causality in fundamental physics including General Relativity and Quantum mechanics
• Explore the mathematical, physical and logical consequences of closed timelike curves and other mechanisms which allow time travels
• Contribute to a comprehensive vision of the underlying issues as well as exploring potential applications to relativistic and quantum metrology and space-time navigation, especially in view of new stellar maps produced by surveying space missions like Gaia.

Although violations of chronology might seem to contradict common sense and lead to logical paradoxes, “time machines” are not ruled out by the current laws of physics.

The conference will highlight new horizons in physics and astrophysics associated with the possible existence of a Time Machine. Examining these fundamental issues provides an opportunity to initiate new ideas and investigations, which explore the role of causality and the interplay between General Relativity and Quantum Mechanics, two theories that on their own have been extensively verified by experiment but have not yet been successfully combined into a single unified theory.

^{The conference is organized by the National Institute for Astrophysics (INAF-OATo), the National Metrology  Institute of Italy (INRiM), the Department of Mathematics “G. Peano” (University of Turin, UNITo), with also the sponsorship of the Italian Society for General Relativity and Gravitational Physics (SIGRAV).
