The rules of time-travel have been debated by scientists and sci-fi fans alike for years but now a student physicist has been able to "square the numbers" to show how paradox-free time travel is theoretically possible.

In a peer-reviewed paper published in Classical and Quantum Gravity , University of Queensland student, Germain Tobar, collaborating with the university's physics professor Fabio Costa, mathematically discovered how, " time travel with free will is logically possible in our universe without any paradox."The math involved in all this is enough to make Will Hunting scratch his head but Tobar, like a different Matt Damon character, has been able to "science the shit" out of theorizing how one could travel through time without causing those pesky logical paradoxes that bedevil many a science-fiction protagonist.One such example is the so-called grandfather paradox wherein, as…
