The Hulk said in Avengers: Endgame that changing the past doesn't change the future; however, the last episode of Runaways showed their time travel efforts in fact changing the outcome and thus paving the way for a brighter future for them all -- furthermore, one of the seasons of Agents of S.H.I.E.L.D. saw the lead agents trying to save the future by traveling into the past (and, while not in fact part of the M.C.U., X-Men: Days of Future Past and, by extent, X-Men: Days of Future Past - The Rogue Cut saw Wolverine alter the past to save the future). If you ask me, whether time travel does or doesn't alter the future or create alternate timelines isn't a solid science. It all depends on a wide variety of factors: the time period one's traveling back to, whether one exists or not in that point in time, the location, the people involved, if they know or not yet know the people who are time traveling in that era, certain events and the circumstances surrounding them, and the means by which time travel is executed, whether it be transferring one's consciousness into their younger body, actually physically transporting back to such an era, using some kind of vehicle like a "time ship" or something like that to time travel, and so on and so forth. Anyone else have any similar analyses?
Steve had to be in the Main Timeline and just not get involved with Business that surrounded the stones or S.H.I.E.LD./Any of the Avengers. It's the only thing that Make Sense as they set it up that Peggy and Steve would always get back to together as far back as Winter Solider. There is only One "Sacred Timeline" for the TVA.
If you are saying that Peggy married Steve in the Sacred Timeline, then that doesn't make sense either. According to Professor Hulk, the past does not change the future. So Peggy had to have married someone else.
According to Anicent One, That whole belief is wrong though,
THE ANCIENT ONE (2012): I'm sorry, I can't help you, Bruce. If I give up the Time Stone to help your Reality, I'm dooming my own.
BRUCE BANNER: With all due respect, I'm not sure the science really supports that.
[The Ancient One creates a projection with a long ray that simulates the flow of time.]
THE ANCIENT ONE (2012): The Infinity Stones create what you experience as the flow of time. Remove one stone and that flow splits. [She flicks the Time Stone projection away and Shows black stream indicating a point of divergence] Now, this may benefit your reality, but my new one…not so much. In this new branched Reality, without our chief weapon against the forces of darkness, our world will be overrun. Millions will suffer. So, tell me, Doctor, can your science prevent all that?
BRUCE BANNER: No, but we can erase it. Because once we are done with the stones, we can return each one to its own timeline at the moment it was taken. So, chronologically, [Holds the Time Stone projection] in that reality, [puts it back to its spot] it never left.
[Bruce's astral form takes the projection of the removed Time Stone, replaces it back amongst the other five, and the doomed alternate dimension fades away, illustrating his point.]
I don't see how that contradicts Hulk's theory.
The Ancient One Only mentions the Stones nothing else. They are what made the flow of time, Let's use The Widows for example, If Steve was to say Rescue Natasha, they would have screwed up the history of the timeline and thus messed with the Stones and it's history as Nat may never become a Avenger, but if he rescue someone who has no Experience with any of the Avengers because they are usually the most who are involved with the stones like say Dottie Underwood from agent Carter then he is good to stay in the past. We see in Mrs. Marvel that not all time travel create Branches as Kamala time travel didn't cause a branch timeline.
Hmmm...
Kamala’s time travel was one of those “What happened happened” sort of things, her time travel created the events that lead to her being born, which allowed her to time travel. It’s the predestination paradox, totally separate from other time travel.
How is that separate from time travel? I'm pretty sure Ms. Marvel is another example of contradicting time travel in the MCU.
I’m not saying it isn’t time travel. It just doesn’t work in the same way with the Endgame rules. I’m saying that Ms. Marvel did not create alternate timelines.
Oh, okay.
What do you think?
