Get To Grips With The Science Behind Avengers: Endgame Ahead Of This Weekend's Re-Release

Time travel can be hard to get your head around at the best of times, but Avengers: Endgame really took the concept to the next level.

Six weeks have passed since the worldwide release of Avengers: Endgame and we are still pretty emotionally fragile about the whole thing. Now, Marvel decides to drop a re-release of the movie in theaters that includes a little bit of bonus footage. Naturally, we are going to go and see it but we're not sure if we can handle watching Iron Man die all over again.

Hardcore MCU fan or not, it's hard to argue that together, Infinity War and Endgame were pretty perfect movies. That says a lot considering the time travel element to the second of the two movies. Doing time travel in a movie and doing it well is incredibly difficult. Marvel knowing that all too well employed the services of a physicist to help them map out the whole thing as accurately as possible.

That naturally made for some quite confusing scenes and phrases when it comes to the layman. Luckily, the aforementioned physicist Dr. Clifford Johnson recently explained the science behind Endgame's time travel to Entertainment Weekly. "What [the filmmakers] wanted to avoid was the obvious paradox of you go back and you change something, and then you see things become," explained Johnson.

That's why Marvel introduced the concept of multiple universes. That if you go back in time and change something, you create a new timeline. The future you traveled back from continues to exist and remains unchanged. "When the Avengers go back in time to recover the Infinity Stones, they discover that their past becomes their future and their present their past." We had to re-read that quote a few times to get our heads around it, but it makes perfect sense.

During the movie, some of the characters joke about other takes on time travel being ridiculous. Honestly, after watching Endgame, we're totally on board with that. Although time travel hasn't technically been discovered (yet) if it ever is, we believe Endgame's take on it will be much closer to the real thing than any other movie has managed. It will certainly be far less messy.
