A Scientist Proved Paradox-Free Time Travel Is Possible A new study claims to resolve a long-standing time travel paradox, suggesting that time travel is both deterministic and locally free. The research, based on observations of a time- traveling qubit, concludes that the present remains unchanged by interference from the past. However, that doesn't mean stepping on butterflies is entirely risk-free. In a peer-reviewed paper published in Classical and Quantum Gravity, scientist Germain Tobar and his co-author Fabio Costa (both affiliated with the University of Queensland at the time) propose a mathematical proof demonstrating the physical feasibility of a specific type of time travel. Their study, titled "Reversible Dynamics with Closed Time-Like Curves and Freedom of Choice," finds a mathematical middle ground that resolves a key logical paradox in certain time travel models. The Mathematics of Time Loops The underlying math is intricate, but the core idea is straightfo...
