Australian physicists from the University of Queensland demonstrated that time travel might occur without logical inconsistencies, publishing their findings in the journal Classical and Quantum Gravity. The research examines closed timelike curves (CTCs), which permit events to self-correct to avert paradoxes such as the “grandfather paradox.”
The scientists note that while the past can be observed and manipulated, macro-level occurrences do not alter drastically. Any attempts to change history will be counterbalanced by spacetime properties. Moreover, the traveler maintains free will and can take actions without causing contradictions.
The work relies on quantum experiments illustrating particle interaction with their prior states without violating logic. The authors stress that this unveils novel avenues for grasping the nature of time and its possible application, though actual journeys remain within the realm of conceptual science and fiction for now.
