You’ve probably seen the posters. Or maybe you've spent three hours scrolling through a subreddit dedicated to the "Sacred Timeline." Whether it’s Marvel’s messy branching paths or the high-concept cosmological models of real-world theoretical physics, the idea of a map of the multiverse has become our generation’s version of the Great Age of Discovery. We aren't looking for the West Indies anymore. We’re looking for the exit door to this reality.
But here is the thing: a map is usually a lie.
In cartography, you’re trying to flatten a sphere onto a piece of paper. In multiversal "mapping," you’re trying to visualize dimensions that the human brain isn't even wired to perceive. We use circles. We use webs. Sometimes we use bubbles. Yet, every single map of the multiverse we create—from Max Tegmark’s four levels to Grant Morrison’s psychedelic DC Comics Orrery of Worlds—is just a metaphor to keep us from losing our minds.
Why DC Comics Actually Built the Most Influential Map
When people talk about a map of the multiverse, they often start with the 2014 Multiversity project. Grant Morrison, a writer known for thinking in four dimensions, decided that DC’s messy history needed a literal, physical chart.
It’s a circle.
At the center, you have the "Orrery of Worlds," which contains the 52 standard universes. Surrounding that is the Speed Force. Further out, you hit the Sphere of the Gods, where places like Apokolips and New Genesis sit. Then there’s the Monitor Sphere, and finally, the Source Wall. This wasn't just some cool poster for a bedroom wall; it was a functional narrative tool. It gave writers a geography of the imagination.
It also highlighted a massive problem with how we think about "other worlds." We tend to think of them as being "far away." In the DC map, they aren't distant in space. They are occupying the same space, just vibrating at different frequencies. Think of it like a radio. You’re listening to 98.7 FM, but 101.1 FM is right there in the room with you. You just need to turn the dial.

The Science: Tegmark’s Four Levels of Reality
Real physics is way weirder than comic books. Max Tegmark, a physicist at MIT, famously categorized the multiverse into four levels. This is basically the scientific map of the multiverse that researchers use to argue whether this stuff is even real.
Level I is the most boring, but also the most likely. It basically says the universe is infinite. If you travel far enough in one direction, you will eventually run into a version of Earth where you had toast for breakfast instead of cereal. Why? Because there are only so many ways you can arrange atoms in a finite volume. Eventually, the patterns have to repeat. It’s just math.
Level II gets into "Eternal Inflation." Imagine a bubbling pot of soup. Each bubble is a universe. In our bubble, gravity works. In the bubble next to us, gravity might be so weak that stars never form. These bubbles are physically separated by space that is expanding faster than the speed of light, so you can never, ever visit your neighbors.
The Many-Worlds Interpretation
Then there’s Level III. This is the one Hollywood loves. This is the "Every time you make a choice, the universe splits" idea. Based on quantum mechanics—specifically the work of Hugh Everett III—this suggests that the map of the multiverse isn't a collection of bubbles.
It’s a tree.
Every quantum event is a branch. You didn't just choose to buy this coffee; in another branch of the wave function, you walked out of the store. This map is terrifying because it means the multiverse is growing exponentially every nanosecond. It’s not "out there." It’s happening inside your cells.

The MCU and the Problem of Visualizing Time as Space
The Marvel Cinematic Universe (MCU) tried to give us a map of the multiverse through the Time Variance Authority (TVA). They showed us a single "Sacred Timeline" that looked like a glowing white rope. When things went wrong, branches sprouted.
By the time we got to Loki Season 2, that map changed. It became a tree—Yggdrasil.
This is a classic human trope. When we can't understand complex data, we turn it into nature. We take the "quantum foam" of high-level physics and turn it into roots and leaves. It’s a way of making the infinite feel manageable. But honestly, the MCU’s map is more about destiny than geography. It’s about who is allowed to exist and who isn't.
Mapping the "Everything Everywhere" Chaos
In the movie Everything Everywhere All At Once, the map of the multiverse wasn't a map at all. It was an everything bagel.
This is actually a pretty profound way to look at it. If you put everything on a bagel—all your hopes, dreams, failures, and every possible version of yourself—it eventually collapses under its own weight. It becomes a black hole. It’s the "nihilism" map. If every version of you exists, does this specific version of you even matter?
The movie argues that the map doesn't matter as much as the person standing next to you. It's a nice sentiment, but it doesn't help the people trying to calculate the cosmological constant.

The Limitations of Our Current Models
We have to admit something: we might be completely wrong.
Some physicists, like Roger Penrose, aren't fans of the standard multiverse theory. They propose things like Conformal Cyclic Cosmology (CCC). In this "map," the multiverse isn't side-by-side. It’s back-to-back. The end of one universe is the Big Bang of the next. It’s a serial multiverse rather than a parallel one.
Mapping this requires looking at the Cosmic Microwave Background (CMB) radiation. Scientists look for "bruises" on the sky—circular patterns that might be the imprints of a previous universe bumping into ours. If we ever find a definitive bruise, the map of the multiverse will look less like a tree and more like a set of nesting dolls.
How to "Use" a Multiverse Map Today
If you’re a creator, a writer, or just someone who likes to think about the "what ifs," there are actual ways to engage with these concepts without getting a PhD.
- Differentiate between "Dimensions" and "Universes." Most people use these interchangeably. They shouldn't. A dimension is a direction (up/down, left/right). A universe is the container. A map of the multiverse shows the containers; a map of dimensions shows the coordinates inside them.
- Look at the "Bulk" vs. the "Brane." In M-theory, our universe is a "brane" (like a sheet of paper) floating in a higher-dimensional "bulk." If you’re drawing a map, you’re drawing the stack of paper.
- Acknowledge the Void. Almost every map of the multiverse ignores the space between. What is the "nothing" that the "everything" sits in? In comics, it’s the Bleed or the Blind. In physics, it’s a mathematical vacuum.
Mapping the impossible is a fool’s errand, but it’s one we can't stop doing. We want to know where we fit. We want to know if there's a version of us that actually finished that novel or married that person who got away.
To truly understand a map of the multiverse, stop looking for a physical location. Start looking for the connections. The "map" is really just a list of possibilities, and the most important point on it is the "You Are Here" sticker on the reality you’re currently inhabiting.
Actionable Next Steps:
- Read "The Hidden Reality" by Brian Greene. If you want the actual science behind the maps without the comic book fluff, this is the gold standard.
- Study the "Orrery of Worlds" poster. Even if you aren't a DC fan, the spatial layout is a masterclass in how to organize high-concept information visually.
- Use the "Tree Logic" for decision making. Next time you have a major life choice, map it out like a multiversal branch. It helps visualize the "opportunity cost" of your paths.
- Check the latest CMB data. Follow NASA’s updates on the James Webb Space Telescope or the upcoming Euclid mission. They aren't specifically looking for "other universes," but the data they find on dark energy is what will eventually draw the real map.
