grandfather paradox n. A causality paradox speculated about in theories of time-travel in which traveling back in time would allow one to alter the conditions at the earlier time in such a way as to make current conditions impossible, as by causing the death of one's grandfather, making one...
Paradox-free time travelThere may be a way to alter the past without breaking the futuredoi:10.1016/S0262-4079(19)32393-0Chelsea WhyteThe New Scientist
Time travel is deterministic and locally free, a paper says—resolving an age-old paradox. This follows research observing that the present is not changed by a time-traveling qubit. It’s still not very nice to step on butterflies, though.In...
A scientist has mathematically proven the physical feasibility of paradox-free time travel. But once you go back, you might not like what you find.
unlike all those other time travel clone games, you must not encounter your past self at all. even looking him in the eye will cause you both to "faint" and create a time paradox, resetting the stage. there's even a horrible little scream that plays when you fail, one that is at ...
The time travel paradox We define the time travel paradox in physical terms and prove its existence by constructing an explicit example. We argue further that in theories -- such as general relativity -- where the spacetime geometry is subject to nothing but di... S Krasnikov - 《Physics》...
pause to wonder if Season Two might not be on as firm a footing as I had first thought. But you can’t count your chickens before they hatch, and we still have half the season to go. With that in mind, let us jump into this episode before the episode starts a paradox it can’t...
Hello my time travel movies fans Yesterday night I watched a wonderful film and I wanted to share it with you. If you didn’t see the ‘Paradox’ time travel movie you should:) Maybe it is not a very new or original concept but don’t worry, I am not talking from the point of vi...

A Predestination Paradox, on the other hand, results in an internally consistent version of history, albeit involving an event that appears to predate the time traveler’s initial decision to travel to the past. A chrononaut visiting the past to prevent someone from being killed may still ultimat...
