Somehow we are less than six months away from Avengers: Endgame. Considering Spider-Man–who along with half of all life in the universe was turned to dust at the end of Infinity War–already filmed his sequel, we’re confident many victims of the Mad Titan will return. The question is how.

How will the remaining Avengers undo the Snappening? Two new Marvel art books might have confirmed the key was revealed at the end of Ant-Man and the Wasp. But the Quantum Realm could be even more important than that, because it could open up all new worlds for the MCU to explore even after Avengers 4.

On today’s Nerdist News, Hector Navarro looks at two seemingly tiny tidbits that might reveal some huge insights into just how important the Quantum Realm will be to undoing Thanos’ Snapture (something Michael Douglas hinted at). They also indicate those annoying time vortexes, the ones Janet Van Dyne warned Scott Lang about before she went poof, will make it possible. Just how many (or rather few) infinity stones will some time-traveling Avengers need to steal to slow down Thanos? And how will that help shape the future of the franchise?

If the Quantum Realm is the key to saving the universe, can we use a time vortex to watch Avengers 4 now? At the very least, can we skip ahead to find out what it’s called?

What do you think? How will the Avengers use the Quantum Realm? Tell us your best theory in the comments below.
