Avengers: Endgame - 15 Essential NEW Rumours & Theories

11. Everything Is A Time Loop

The Theory

One theory on Reddit, which is pretty damn compelling, states that everything we've seen in the MCU since the time of Doctor Strange's solo movie has been a time loop, which will be broken only in Endgame. That theory points towards Bruce Banner mentioning "this is a time loop" in Age Of Ultron and how illogical the maths of Strange only seeing one positive outcome in 14000605 universes would be.

The logic suggests that Strange doesn't check different realities (that would require the Reality Stone, not the Time Stone), but that he saw 14000605 loops UNTIL the Avengers won, and mentions the Time Stone's mysterious glow as indication that it was active when he handed it over to Thanos.

Response

It's the point about the Reality Stone that's so compelling here. The Time Stone being active is something we've seen theorised about before, but that detail feels like a bit of a game changer. And the theory's mention of Ant-Man being outside of the loop thanks to him being in the Quantum Realm also gives us a means to imagining a key to break the loop too.

If this isn't true, it's an interesting alternative Marvel could have gone with.
