In my opinion yes because when somebody changes an event there always are dumb consequences that are literally unrelated to the event that person changed. For example i go back in time to save John Lennon but now I'm born as a female instead of as a male. In the MCU when you change an event nothing happens because when you kill a past version of you you still exist
@Xandermcc You 5 seconds explanation makes a lot sense I had never thought of that, I always thought "how would Nora dying a moment later affect so much" but your explanation makes a lot of sense. Although, what about how other people's schedules would still be the same, so Barry would have to arrive to those on time, which could "course-correct" his timeline again and set him back on track to the events of the normal timeline? Well I guess since he already arrives late for everything (before becoming a speedster at least) it may not have much of an effect... idk...
I also agree that time travel like that should have many unforseen effects. The only problem is, the Arrowverse is not consistent with this, especially on Legends of Tomorrow. Although it's somewhat justified because you don't want to have to change the cast of the show every time you have time travel (see here).
For example, you have Flashpoint have ripple effects, but then for example, Eobard waiting over a minute before turning on the accelerator in What's Past is Prologue should have many more ripple effects than it does (it doesn't have any that we know of), since so many of the meta-humans who got powers due to specific situations would be in slightly different situations at that point.
Also, because of the butterfly effect, Eobard probably should have been erased the moment he first interacted with The Flash in the past, or at least once he killed Nora. The Flash could have taken place in a closed loop/predestinative paradox (as Barry seemed to think would be the case in some episodes of season 1 when he learned his future self fought Eobard) up until the moment Eddie killed himself, which established there was in fact an original timeline. Also, Savitar is another example of a predestination paradox, though he could also potentially have resulted from a linear Back to the Future style system. For example, Barry initially makes time remnants to stop DeVoe or someone else, or Iris originally dies another way, etc, but once he becomes Savitar it "closes the loop" and turns it into what looks like a predestination paradox.
Well we know the events in The Past is Prologue already happened as Cisco mentioned getting some drinks before turning on the accelerator.
Also it's not just the lateness. It's that early on changes because of said lateness result in the future changes. For example, Joe arriving at the house late, Barry saying different things as a child on who did it because he showed up later. Events that then lead to further changes and not just a consistent time delay. So yeah, it does cancel out and you are right, but the changes are still started and move forward on their lonesome for that seventeen years.
Ok that makes sense, good thinking. And while Barry would have arrived back at his house at the same time because Eobard killed Nora after future Barry took him away, we see in the Pilot that the police were already there, so that still makes sense. Also, I imagine Eobard's longer/neater hair in episodes like Therefore I Am and What's Past is Prologue is also somehow a result of Flashpoint.
And about What's Past is Prologue, that also makes sense. I also saw a theory that Harry figured out Barry was from the future in the episode, which is why he was confident the recreation of the accident that gave Barry his powers would work. And while the original flashback in Things You Can't Outrun didn't have Wells pausing before turning the accelerator on, that could just retroactively be "tricky editing" to deceive us that there was no pause in between.
However, why then is the time travel in What's Past is Prologue different from episodes like Flash Back, where the past is definitely altered?
Barry did not change baby Sara's gender, baby Sara is a different person to baby John. Even if John and Lyla conceived a second later than they had, it would've been a different child.
I agree, though I think in this context people may often say that as a shorthand for saying the person was turned into a different person, even if it's not completely accurate.
It's not dumb but definitely confusing. Nora Allen dying 5 seconds later has more consequences than a stuffed toy fighting a time demon in the wild west.
That's because the Time Bureau restored events as per normal.
I wonder why the Time Bureau doesn't interfere with speedster time travel. Maybe they too are affected by it so they can't tell the difference.
Given we see that they are affected even by the anachronisms themselves, it seems so. It's a different kind of time travel as we have seen a few times.
What do you think?
