True or False Quiz: The Multiverse According to Laurent GuillemantLaurent Guillemant is a French physicist who works on AI and quantum physics.
He has a cool idea about the multiverse that mixes science and a bit of philosophy. For him, our reality is like one “branch” among thousands of others, created by our choices and intentions. It’s not just sci-fi: he uses quantum mechanics, where particles can be in several places at once until we look at them.
But Guillemant goes further: our mind can steer these branches toward a better future. I picked everyday examples to keep it simple and fun. Ready to test your ideas? Answer true or false to each statement, and the answer is right below (no spoilers first!).
1. In Guillemant’s theory, if you miss your bus one morning, it’s because there’s another multiverse branch where you caught it and your day goes perfectly.
False.
Guillemant says “missed” events (like a bus) are often rejections of branches where things would have gone wrong. For example, in another branch you take the bus… but it crashes. Our reality filters paths to protect us, like a GPS avoiding traffic jams. Think of those times a delay saved you from a bigger problem!
2. In Guillemant’s multiverse, Schrödinger’s cat—locked in a box that might kill it or not—is both dead and alive.
True.
This is the classic quantum example Guillemant loves. Before opening the box, the cat is in “superposition”: dead in one branch, alive in another. For Guillemant, our observation (or intention) picks the branch. Imagine: you open it and the cat is alive—nice, you “selected” the good reality. It’s not magic; it’s quantum—and it happens all the time!
3. According to Guillemant, we can physically travel to another multiverse branch, like in a superhero movie.
False.
No way! Guillemant says branches are like parallel movies—you can’t jump into them with a machine. You stay in your branch, but your decisions and mind guide it toward positive futures. Real-life example: instead of forcing a trip, meditate on what you really want—it’s like switching lanes on a highway without changing cars.
4. In Guillemant’s model, a strong intention—like wanting to heal from an illness—can create a branch where you’re perfectly healthy.
True.
Guillemant links this to consciousness: our mind isn’t passive; it “pulls” the good branches. Everyday example: people who visualize healing (like in positive therapy) often see surprising improvements. It’s not magic; it’s aligning your choices with hidden quantum probabilities. Try it with a small goal, like nailing a job interview!
5. Guillemant’s multiverse says every possible choice really exists, including ones where dinosaurs never went extinct.
True (with a nuance).
Yes, in his theory—based on Everett’s “many-worlds”—every quantum possibility makes a branch. Concrete example: imagine a coin flip—in one branch you win, in another you lose. For dinosaurs, a branch might have the asteroid missing Earth. But Guillemant adds that our reality is “synchronized” by time and consciousness, not total chaos. Picture a tree with billions of leaves, but you walk on just one branch.
6. Guillemant believes the classic multiverse theory—with identical universes that are perfect copies of us—is the only true explanation of reality.
False.
He actually criticizes those “flat” multiverses (perfect doubles of you elsewhere). For him, it’s too mechanical; he prefers a dynamic multiverse shaped by consciousness and non-linear time. Real example: instead of saying “there’s a rich you somewhere else,” he says “create your wealth by choosing better here.” Way more empowering, right?
That’s the quiz!
If you answered them all, count your trues: 3–4, you’re already a Guillemant multiverse pro; 5–6, future physicist?

Just let us know. This was fun to make—and who knows, maybe in another branch you’re the one asking the questions!
