Are We Just a Level in a Simulation?

Introduction: Reality or Rendered Illusion?

Understanding Dimensions as Levels

To understand the theory, let’s begin with dimensions. A 1D world consists only of length—like a line. A 2D world introduces width—think of a flat square. Our world adds a third dimension: depth. These are often explained in the context of Edwin Abbott’s novella Flatland, where 2D beings cannot comprehend the existence of 3D space. To them, a sphere passing through their world would look like a growing and shrinking circle. In this same way, could our inability to perceive higher dimensions simply mean we’re not designed to access them?

If we imagine dimensions as simulation levels, 3D is not the pinnacle of reality, but just another plateau. We experience time as a fourth dimension, but theories in physics suggest the existence of additional spatial dimensions beyond that. Are we just players in Level 3, oblivious to the rules of Level 4 or 5?

The Simulation Hypothesis: Scientific Theories

Philosopher Nick Bostrom introduced the simulation hypothesis in 2003. He argues that at least one of the following statements must be true:

1. Human civilization will never reach a post-human stage capable of running simulations.
2. Post-human civilizations won’t be interested in running simulations of their ancestors.
3. We are almost certainly living in a computer simulation.

The third possibility is the most provocative—and the one with increasing theoretical support.

In 2012, Dr. Silas Beane and his team at the University of Washington proposed that if our universe is simulated, it would have observable limits—similar to how pixels constrain a digital image. Their work speculated that ultra-high-energy cosmic rays might reveal a grid-like structure to the universe, akin to the lattice used in video game simulations.

Meanwhile, physicist Dr. James Gates discovered what appeared to be error-correcting codes—similar to those used in modern computing—embedded within the equations of supersymmetry (a subset of string theory). This raises a chilling question: why would nature need built-in debugging unless it was programmed?

Dimensional Constraints: Clues We’re in a Lower Level

So why can’t we access higher dimensions or realities? One answer might be: we’re simply not permitted. Like characters in a game coded with specific limitations, we’re only aware of what our environment is designed to allow.

Take quantum mechanics, for example. The double-slit experiment shows that particles behave like waves until observed. It’s as if the universe renders itself only when watched—a behavior disturbingly reminiscent of how video games conserve processing power by rendering environments only when needed.

Quantum entanglement is another clue. Two particles can affect each other instantaneously over vast distances, violating the known limits of information transfer. This “spooky action at a distance,” as Einstein called it, may be the result of underlying code that governs interactions outside our 3D view—perhaps from a higher dimension.

The Multiverse and Nested Simulations

If we’re in a simulation, could there be others? Some scientists and philosophers think so. The multiverse theory suggests an infinite number of universes, each with its own set of physical laws. If every simulation spawns others within itself—like a game running a game—we could be in a “simulation within a simulation.”

Pop Culture That Explores This Idea

Several science fiction stories have explored this idea:

• Levels (2024) – Characters move through different reality levels, each governed by its own logic and hazards. Each progression reveals a deeper truth about their existence.
• The Matrix (1999) – Humans unknowingly live in a simulated world designed to enslave them.
• Steins;Gate – Reality is a branching timeline, where small changes spawn new world lines, each layered upon the last.
• Rick and Morty – In several episodes, the characters discover they’re inside simulations of simulations, sometimes without realizing it.

These stories resonate because they reflect our suspicion: maybe what we see is not all there is.

What This Means For Us

If we live in a simulation, does anything still matter? This is a central ethical question of the simulation hypothesis. If everything is code, do free will and morality exist? Or are we just enacting a script?

Some argue that even if we’re simulated, our emotions, decisions, and experiences are real to us. Whether or not there’s a “player” behind the screen, the narrative of our lives is still meaningful.

And if simulations can exist, should we eventually try to escape ours—or build our own?

Conclusion: Game Over or Just Getting Started?

Every dimension we uncover might just be a new level in an unfathomably complex simulation. The more we learn about our universe, the more it resembles a digital construct. Patterns, laws, and even “glitches” are starting to look less like natural phenomena and more like architecture.

Are we biological beings navigating a physical universe—or digital avatars within an ultra-advanced simulation? Asking these questions may be the first step toward reaching the next level of understanding. As we consider simulation theory and dimensions, parallels between digital architecture and our layered reality begin to emerge. Even if these theories remain unproven, they push us to examine the foundations of existence and question what it truly means to be real.

Stay curious. Stay critical. Maybe that’s what the simulation wants—and needs—from us most.
