In some alternate reality, no one is talking about All at once, everywhere. The extraordinary sci-fi story, created by the Daniels — Daniel Kwan and Daniel Scheinert — ended its jackpot season yesterday: the Oscar for best film, one of seven statuettes he received last night. And while we could spend weeks celebrating the film’s benefits —because there are so many—, here we can’t help but think of just one thing: Could the multiverse proposed by the tape exist in reality?

If you haven’t seen it yet, here we leave you, not one, but two reviews we’ve done. But, in general lines, the central plot of the film develops around the idea that there are multiple universes. He argues that, in these other realities, there are alternate versions of ourselves: more powerful, more humiliating or even contradictory. That’s why it’s so fascinating. Yes, it might sound like Marvel to you.

We don’t want to drive you crazy. In fact, we warn you that Hugh Everett III, the American physicist who first proposed the theory of parallel universes, was ridiculed by his colleagues at the time, left physics overwhelmed with the complexity of his postulates, and died prematurely. A heart attack in 1982. So take it easy.

What’s the multiverse they talk about all at once everywhere?

Yes, the existence of the multiverse has not been proven, but the very idea continues to keep many up all night. It is a concept with many theories, which sometimes dances between the scientific and the philosophical. Physicists George Ellis and Joe Silk described the multiverse debate in an article published in Nature in 2014, as “Fight for the heart and soul of physics.”

One of the simplest explanations of the multiverse that we see in All at once, everywhere It has to do with the theory of “cosmic inflation”. Let’s go to “multiverse for beginners” mode – because that’s how we asked them to explain it to us.

Does he ring a bell? big Bang? When the Universe grew exponentially in less than the blink of an eye after the Big Bang, some parts of spacetime expanded faster than others. This could have created a kind of bubbles that would harbor their own universes. These other “bubbles” would be universes parallel to ours, which could have very different physical laws. Sort of like the scene in the movie where everyone has sausage hands.

Evelyn, the protagonist of ‘Everything at the same time everywhere’.

A lot? This explanation may be simpler: the “many worlds interpretation” of quantum mechanics. This has to do with what you explained everett iii – the one with the heart attack. In the world of quantum reality, everything is described in probabilities.

According to this version of the multiverse, any event can have more than one outcome, either because we make some decision or because some random event occurs that changes everything. Each decision creates an alternate timeline in which we choose something else. Something like what we think when we ask ourselves: what would have happened if…? Except actually this other thing would be happening in a parallel universe. Like when Evelyn, the protagonist of All at once, everywhere, the universe jumps in and gets to see a world where she has decided not to marry. And he saw that it was a happier world.

Could we jump between universes?

The directors of All at once, everywhere said in an interview with New York Times who were inspired by what we just explained: both the many-worlds interpretation of quantum mechanics and the idea of ​​cosmic bubble universes.

Now: how about being able to jump between these realities, like in the movie? There is still no theory on how to travel between different parallel universes. The closest that has ever been written has to do with the idea that these “bubble universes” collide with each other, leaving a kind of “scars” that may give us some clue to the existence of other realities.

One of the craziest scenes ever All at once, everywhere.

The Daniels explained that their film is less about physics than how physics makes you feel. “If you could see alternative lives, it would put you in a spiral with all the lives you could have led and all the choices you could have made,” Scheinert said. The New York Times newspaper.

They clarified that their multiverse is less science and more metaphor. “I grew up in a very religious home, so everything mattered… And when it all matters, it’s a horrible experience to navigate the world.”said, in turn, Kwan, the other creative. This is paralyzing: “Everything, every action, is full of remorse, and every action is full of guilt.”

Perhaps, in the midst of so much reflection on bubble universes, on the arbitrary or insignificant aspects of our existence, we can understand that, in reality, “nothing matters”. And, if nothing matters, anything is possible.
