Physicists propose a paradox-free theory for moving through time

Australian physicists have put forward a new theoretical framework for time travel. Their work suggests that moving through time could avoid paradoxes, even when interacting with past events. The research builds on earlier studies but remains purely conceptual at this stage.

In 2020, researchers Orlando Lansberg and Germain Tobar from the University of Queensland introduced a model based on closed timelike curves (CTCs). These theoretical paths allow time loops without breaking the laws of physics. Their study argued that the universe would automatically adjust to prevent logical contradictions.

The team's quantum models showed how attempts to change key historical moments would instead reshape reality. Rather than creating paradoxes, the universe would maintain a consistent timeline. This 'safeguard mechanism' ensures that causality remains intact, no matter how events unfold.

As of February 2026, no practical experiments or real-world applications of this theory have been reported. The work continues to explore time's fundamental nature, but concrete implementations are yet to emerge.

The findings provide a fresh perspective on time travel, though they stay within the realm of theory. By demonstrating how paradoxes might be avoided, the research offers a foundation for future studies. For now, the ideas remain speculative, with no immediate plans for experimental testing.
