I was wondering why Nebula didn't die after killing her past self. I mean, grandfather paradox???
Who is he?
Well, she was the good twin. Gamora is going to need someone to help her find her way back to the Guardians.Yeah that irked me but I'm sure they can explain it away somehow
Ah good, so I wasn't hallucinatingThey sure focused on him for a good while

I actually meant that it's a plot issue. Should have elaborated, sorry.That doesn't really have anything to do with the grandfather's paradox issue, but they do need her alive, plus she's cool

Echoing the quantum rant, I was wondering why Nebula didn't die after killing her past self. I mean, grandfather paradox???

When you return to the past and alter any event in it, you are creating a separate timeline from that point on, that timeline will have its own future. So for the Nebula in the past, a new timeline is created where she's killed and does not exist anymore. However, the Nebula that went from to past has her own timeline from where she came from, where she was still alive; she was never killed by another Nebula after all.
Good question/observation. I have no idea.Another question: did you also notice the boy at the ceremony, standing behind Bucky and Sam? Who is he?
So you're saying I mistook the branching off timeline for the timeline that they were in, rather than the past that they created which followed them into the future that was corrected, and thereby any "past incarnation" of a person from the timeline which we follow was never able to have an effect on the "present selves" at all?In regards to Nebula, there's one thing though that is mentioned in the movie by the ancient one when they are describing the time flow and that is also kind of the solution to the Grandfather paradox:

Some Science stuff:
In reality, everyone and everything has their own "worldline" which is the current/present/future of you described through spacetime. You are following along that line as your current self and there is only 1 world line for "you". Time travel, at least back in time, is not allowed by our current physics. This is because everything is limited by the speed of light, information has to go beyond the speed of light to revert time events as Einstein's equations state that the faster you travel towards the speed of light, the slower time will flow, traveling faster than the speed of light would theoretically revert time, but there is currently nothing that allows it (yeah not even you, black holes). So altering our own "worldline" by going back is currently not possible, sadly.
There is one exception to this and that is the concept of and infinite amount of realities existing parallel to each-other where every possibility of "you" exists for every hour/minute/second/millisecond/planck second. But this is an extreme concept of multiple realities/dimensions which so far cannot be proven (fun theoretical concept though, would be cool if we could jump between multiple realities of ourselves in a flash).

dk if any of you stayed through the whole credits, but the hammering sound at the very end of everything was also curious.

It was funny how expectant everyone was (or rather, those who hadn't left). It was rather obvious that there wouldn't be a post-credit scene, with how little they have to easter egg.Idk if any of you stayed through the whole credits, but the hammering sound at the very end of everything was also curious.
I read that it was the sound of Tony Stark building his first suit, idk if that's accurate or not.
Whether it means anything for the future or was just like an homage kind of thing, either way it was a nice touch.
During the movie, I was thinking how changing the past was affecting not just the past but the present too, but it seems that like in some Doctor Who episodes the future/present was still in flux for the time that took to bring the stones back again. Although in DW there would have been an element of time catching up eventually, so that was where I was going...Eeeeeeehm....yep?! That's the whole take on the paradox, you have to accept that altering the past creates a new future rather than changing it. Else you'd be stuck in the paradox (you change the past, which changes the future, which then changes the past again, etc. etc.). Both the paradox and branching are possible, but for this movie, we'd go with the branching, for the plot's sake.

But as you said, the repercussions of playing with time in that fashion are not yet provable, so it might just as well be that the future/present would always be in the flux-state for as long as the stolen stones were in those spacetime coordinates.
