Is there anything I’ve missed beyond Banner saying it doesn’t work like other movies and the Ancient one talking about branched timelines. Are there two branched timelines now? The original MCU and now MCU up to 2014 then no Thanos.
Ok.
This basic version is "you can't change
your past". Anything they do in the past won't change your present (because you already lived the past. It happened for you). . It's very different from most other media presenations of time travel. But the present is fixed. You can't change it, because it's you. If you take that as the starting point it largely makes sense.That's no cause/effect
That's why !PresentNebula could shoot !PastNebula without herself disappearing/changing. (And !PastThanos and his army were destroyed with no effect on our history)
The Ancient one explains it as if you change the past you make a new timeline (i]your[/i] timeline doesn't change). So when Bruce took the stone, he was making a new (darker) timeline for her world. That's why Bruce said they'd take the stone back to her.
So there's potentially many different timelines around now - 2012 Morag split, 1970s Tessect/Pym Splt, 2013 Ether Split etc (My guess is Doctor Strange 2 might explore them)
This only problem with the "past becomes different timelines" thing is that then how does Cap go back, make a different timeline where he stays....but then end up in our timeline at the end to pass on the shield?
(Edit This also means that even if Thor saved his mum, he'd have made a different timeline where she lived, when he came back she'd still be dead)
