Computer solves a major time travel problem
- coldtea 10y agoHow is the first solution a new solution? The Marty descending by the time-travelling Marty who "becomes his own grandparent" either has other genes than the original Marty (and thus is either another person, not the one that originally came, which maintains the paradox), or always was his own grandson (so this new solution is just the already known time-loop solution a la 12 Monkeys).
