Time travel, a long-time fascination, may have a chilling side effect of total memory loss, according to recent research.While physics doesn't rule out time travel, building a working time machine remains challenging due to complex conditions required.Mathematician Lorenzo Gavassino's work suggests a closed timelike curve trip could erase memories due to thermodynamic laws.Time loops may reverse memory formation and aging processes, leading to the vanishing of memories during the journey.Clocks and matter may be disrupted, leading to broken clocks, scrambled matter, and loss of memories in a time travel scenario.Traveling through a loop in time could result in forgetting everything experienced during the trip, with memories being erased.Gavassino's work offers a glimmer of hope that some memories may survive the entropy problem, potentially making time travel less bleak.The findings warn dreamers of time travel to consider the potential reality of memory loss and disruption of physical laws.Despite challenges, the possibility of loopholes or undiscovered physics hints that time travel may not be entirely ruled out.The research findings on the impact of time travel on memory are published in the journal General Relativity and Quantum Cosmology.
