Scientists have conducted the world’s first successful time travel experiment, proving once and for all that time travel is possible. The study of closed timelike curves provides valuable insight into particles that can loop back on themselves, breaking free of linear time. This creates a CTC, almost like a pathway to travel back through time. The source of time travel speculation lies in the fact that our best physical theories seem to contain no prohibitions on traveling backward through time. This would create a “Closed timelike curve,” or CTC, a loop that could be traversed to travel back in time.
Experimenting With CTC’s. Single particles of light to simulate quantum particles travelling through time were just used by scientists from the University of Queensland, Australia.
Much of their simulation revolved around investigating the “Grandfather paradox,” a hypothetical scenario in which someone uses a CTC to travel back through time to murder her own grandfather, thus preventing her own later birth.
