Avengers End Game - Alternate Realities

alt
So Before Infinity war we got many fan theories and after infinity war it just got doubled.So now only 100 days are left to avengers End Game , here another fan theory by a reddit user. In End Game we may see many things such as Quantum Realm , time travel ,Barf technology , alternate timeline .All other plot holes which we have seen till now are going to be solved in this movie.So we know nothing about this movie and Trailer is also not helping us with this matter , So many theories are coming which tells us about Hela's return in end Game , Ultron's return in End Game and sacrifice of a main character and many more .So here comes this theory which tells about alternate realties in MCU.

So from End Game set images we can guess that something like time traveling is going to happen in End Game .But we must not forget that Russo Brothers are not going to present a simple story which everyone can guess .This theory is also very complex so read carefully .

This theory states that our heroes have to face multiple realties and dimension.Multiple realties means like quantum realm has a world where different creatures lives there.Same way there are different dimensions where different creatures lives and dew are identical to our earth.In comics there are alternate characters of almost every superhero.So in Endgame we saw Captain America twice . So according to this theory the Captain America which was crying was of our world and the captain which was in suit was of alternate dimension .So we can say that black widow went to alternate dimension where she met Hawkeye who was of alternate realty and we saw a leaked image were pepper was wearing a suit and this could of other realty where she would be known as Iron Woman.So the plan about which Widow and Cap were talking could be going to different dimensions and constructing a team against Thanos.

So now lets come to alternate realties.So every action done in our main universe will give different result thus creating alternate. So according to Dr.strange we have 14,000,605 alternate realties .So marvel could explore some of realties and show us where we will know what would have happened if Peter Quill have not beaten Thanos, if Spider Man would have taken out the Gauntlet or what if Dr.strange would not given the time stone to Thanos. And at the end of the movie, every changer would be set to normal including to of alternate dimensions or it will confuse the audience like X men Days of future past.

Here comes the butterfly effect which means a small event in any dimension which will give a huge effect in future.So if someone will play with time and dimension then consequence will be there .So according to theory , here comes the Living tribunal , if you don't know the living tribunal then, he is a cosmic entity who keeps a balance in different realties and dimension of marvel universe and this cosmic entity will help everyone in the end .

We have seen a glimpse of living tribunal in the Dr.Strange movie were Kal Mordo uses a weapon know as the the staff of the living tribunal.So this confirms that the living tribunal is present in MCU.

But guys at the end it is a fan theory not a spoiler , so we cannot blindly trust this and we have to wait till April to know the truth.
