Yes, it logically should be a paradoxbut then again, pretty much all the time travel in bttf2 and 3 involved paradoxes i think bttf2 established that the bttf series uses a version of the 'many worlds' theory of time travel, wherein, every time jump to the past creates an alternate timeline. So neither backward causation nor time travel logically entails each other and time travel is distinct from back-in-time travel of the problem can be found in the philosophical literature before michael dummett and anthony flew initiated their discussion in the mid 1950s dk, 1976, “the paradoxes of time travel”, american. How would a philosopher explain the time travel paradoxes 2003 forthcoming) describes a version of 'time travel' where the time traveller hops to alternate time streams for example, you could hop to a time stream where it is september 10, 2001 and foil the terrorist attack on the twin towers that might make you feel good for a while. This relates to a direction in time, proving there's a well-defined direction in time and we will always travel from past to present, marcus scheck from the university of the west of scotland told kenneth macdonald at bbc news at the time.
Depends, what kind of time travel is involved is it transporting your present self into the past, thus creating a timeline in which your present and past selves could co-exist (ala back to the future) or or is it the kind of time travel where you go back in time and inhabit the same body of yourself in the past, but with all your future knowledge (ala hot tub time machine. In addition to prohibiting the grandfather paradox, the p-ctc theory also has the advantage that it doesn’t require the distortions of spacetime that traditional time travel theories rely on. Explores time and space, time travel, and some of the paradoxes involved in time travel the author examines the science and science fiction of many popular ideas sagan, carl.
Time-travel in the quantum world seems to avoid famous paradoxes the experiment shows bizarre behaviour of such quantum particles but on larger scales time travel still remains implausible, say. The predestination paradox involves a cause for time travel that wouldn't have occurred without that time travel in effect meaning the instance of time travelling is causing itself, thus it's. I hope to lead the reader through a discussion of the nature of time and space and then to show the physics involved in creating a time machine then i shall discuss the rather outrageous consequences that time travel holds for the nature of the universe.

The first video, titled 3 time travel paradoxes, talks about three different types of paradoxes associated with time travel the first is the bootstrap paradox, which states that objects involved in time travel may not necessarily have an origin, as an existing object from the future may be taken back to the past, where it could continue to.
The grandfather paradox is a paradox of time travel in which inconsistencies emerge through changing the past the name comes from the paradox's common description: a person travels to the past and kills their own grandfather before the conception of their father or mother, which prevents the time traveler's existence [2. The time travel paradoxes which follow fall into two broad categories, namely 1) closed causal loops, such as the predestination paradox and the bootstrap paradox, which involve a self-existing time loop in which cause and effect run in a repeating circle, but is also internally consistent with the timeline's history, and 2) consistency paradoxes. From millennium-skipping victorians to phone booth-hopping teenagers, the term time travel often summons our most fantastic visions of what it means to move through the fourth dimension but of course you don't need a time machine or a fancy wormhole to jaunt through the years. Time travel is a sticky subject for a plot device in that it comes with a set of built-in contradictions could a time traveler bring back objects or information from the future if those objects.
A time travel story can simply use time travel as a vehicle to get the hero to the adventure towns, or the phlebotinum involved can be a key plot driver no matter what story type the hero is going to need a time machine or time master to get around. The bootstrap paradox is the opposite of the classic grandfather paradox: rather than going back in time and preventing oneself from going back in time, some information or object is brought back. The physics of time travel is it real, or is it fable in hg wells’ novel, the time machine, our protagonist jumped into a special chair with blinking lights, spun a few dials, and found himself catapulted several hundred thousand years into the future, where england has long disappeared and is now inhabited by strange creatures called the morlocks and eloi.
Relativity and ftl travel by jason w hinson ([email protected]) it discusses the various problems involved with ftl travel and how they apply to particular ftl concepts we can allow for non-warp/non-subspace-using ftl travel in trek while still preventing unsolvable paradoxes further, consider time travel in trek actual time. Among those involved in the very real debate on the possibility of time travel was the inestimable stephen hawking, and others involved in the research are serious and respected scientists time travel has taken its first steps out of science fiction. There are too many paradoxes involved and i think that this is evidence that time travel is indeed impossible in reality, but movies and books about it are a hell of a lot of fun and can lead to interesting conversations. The scientific part of this site has examined time travel as a feasible mode of transportation through time it has also shown that the most interesting direction for travel is back into the past but suppose time travel were possible is it ever ethical to travel back in time to change events that.
