There are also paradoxes associated with time travel. The famous “ grandfather paradox ” is a hypothetical problem that could arise if someone traveled back in time and accidentally prevented ...

Germain Tobar and Fabio Costa, both of the University of Queensland at the time of the paper’s publication, worked together on the study. In “ Reversible dynamics with closed time-like curves and ...

If Costa and Tobar's paradox-free model proves correct, it fundamentally changes our time travel narratives. This concept inspired my new novel "The Memory Collectors", which explores what time ...

So, he does what any inventor cat would do: he builds a time machine, to travel back to the novelist’s final hours, in hopes of preventing the tragic act. But things are never that easy.
