Ulvi Yurtsever is a contemporary theoretical physicist whose work engages with the physical and philosophical plausibility of time travel, particularly closed timelike curves in general relativity. He has collaborated with prominent physicists including Kip Thorne on the question of whether the laws of physics permit or forbid backward time travel. His contributions sit at the intersection of physics and the philosophy of time.
Co-authored foundational work on the physical plausibility of closed timelike curves
Collaborated with Kip Thorne on constraints governing time travel scenarios in general relativity
Contributed to the theoretical case against time travel via consistency and stability arguments
Engaged with chronology protection conjecture debates in the physics-philosophy literature
