What Version of the Multiverse Are You In?

A reflection on quantum reality, perception, and the science behind simultaneous outcomes.

We trust our senses. We are certain the ground beneath us feels firm, the chair we sit on offers support, and the objects we touch confirm that the world is stable. But what if this solidity is an illusion? What if what we experience is just one version among many, a single thread in a much larger multiverse shaped by observation, perception, and choice?

Modern physics challenges this intuitive certainty. Quantum mechanics, which studies tiny particles, shows that reality may not be definite at all. Instead, reality might come from countless possibilities existing together, forming a fluid state rather than a fixed one.

What if this uncertain nature of reality does not stop at the atomic level? What if it bleeds into our daily lives, our moods, our successes and failures, our sense of control? The idea that our perception of reality influences our experience is not new. But the latest developments in quantum mechanics, neuroscience, and psychology suggest that this connection may be far deeper than we ever imagined.

The Fragility of the Physical World

Physicists have long known that matter is mostly empty space. The atoms that make up everything around us are mostly void, with tiny energetic particles scattered within. Even these particles behave strangely. In quantum mechanics, electrons do not exist as clear, single objects until observed. Instead, they float as clouds of potential outcomes. Only when we measure or look do they settle into one definite result.

This means that at the fundamental level, the universe does not exist in a definite state unless it is being measured. It suggests something deeply unsettling: the solid world we interact with is, in some way, a construct of observation. Not just in a poetic or philosophical sense, but in a literal, physical way.

Could this explain why two people can experience the same event in completely different ways? Could reality, as we experience it, be shaped not just by external conditions but by our internal state, our beliefs, our emotions, our expectations?

This tension between possibility and collapse is famously illustrated by Schrödinger’s Cat, a thought experiment in which a cat is both alive and dead until observed. Originally meant to expose the absurdity of quantum theory when applied to real-world objects, the metaphor now resonates with a broader idea: that our reality might also remain in a state of potential until we engage with it.

The Influence of the Mind on Reality

Psychologists have long studied how perception shapes our experiences. A person in a good mood sees the world as brighter, opportunities as more abundant, setbacks as temporary. Think about days when everything seemed easy because you woke up feeling good, or how your whole day can seem darker if something minor upset you in the morning.

Someone in a depressive state, on the other hand, perceives the same environment as tedious, tough, and filled with obstacles. The phenomenon is not just metaphorical. Brain scans reveal that different emotional states activate different neural pathways – the connection between neurons that enables signals to be transmitted throughout the nervous system, literally altering how we process sensory information.

The “locus of control” theory in psychology suggests that individuals with an internal locus, those who believe they have control over their fate, tend to achieve more, persevere through difficulties, and maintain better mental health. Those with an external locus, who believe fate, luck, or outside forces dictate their lives, often feel powerless and struggle with setbacks.

But what if this goes beyond psychology? What if, much like the quantum wave function, our mental state collapses the possibilities around us into the outcomes we experience?

The Parallel Realities Within Us

In quantum physics, the idea of superposition suggests that a particle can exist in multiple states at once until observed. Some interpretations take this further, suggesting that at each moment, reality splits into different parallel outcomes.

What if every moment is a crossroads? A version of you is succeeding, another is failing, and yet another is taking an entirely different path. Without realizing it, could you be shifting between these possibilities based on nothing more than your perception?

Consider this: when you wake up in a bad mood, your perception alters your day. You become more irritable, notice more negative things, and make decisions that lead to worse outcomes. Conversely, on days when you feel confident and optimistic, you seize opportunities, interact more positively, and experience a better reality. 

Sometimes, you may even feel that a better mood is within easy reach, as if you just had to extend your hand to catch it. But you find yourself pulled back, blocked by an invisible wall that prevents you from making that change. What if these are not merely psychological effects, but actual shifts between possible realities?

It would mean that failure is not an endpoint but one of many versions of the self that we can navigate away from. That success is not predetermined but emerges from a field of potential selves. And crucially, that free will exists not in some abstract philosophical sense, but in a tangible quantum sense where our focus and intent shape the trajectory of our lives.

All these theories seem separate at first glance: quantum mechanics, perception shaping our experience, neuroplasticity – the ability of the brain to form and reorganize synaptic connections, and the psychology of belief. But could they be connected more deeply than we realize? What if they are all pointing toward a hidden truth: that our minds interact with reality in ways science is only beginning to notice?

Is Reality More Malleable Than We Think?

If the world around us is truly dependent on observation, then reality is participatory. We are not just passive travellers through a fixed universe but active sculptors of our experience.

Suffering, loss, and failure are real, and success cannot simply appear by wishing it into existence. Yet how we see the world and the choices we make might shift the likelihood of different futures becoming our reality.

Science increasingly supports these ideas. The placebo effect suggests that belief alone can change our bodies. Studies show our thoughts physically change the structure of our brains over time. Some scientists even suggest that our decisions might follow the same strange rules as quantum particles, making reality far more flexible than we thought.

What if reality itself operates like a probability wave, and our choices, both conscious and subconscious, constantly shift us between different potential versions of our lives?

The Science Behind the Ideas

This article builds on established research in quantum mechanics, neuroscience, and psychology. Science confirms that particles exist in probabilistic states until observed, perception influences cognition, and belief alters physiological responses. These findings are widely accepted, though their deeper implications remain debated.

Quantum mechanics, through the observer effect and wave-particle duality – where waves can exhibit particle-like properties while particles can exhibit wave-like properties, shows that observation determines reality at a fundamental level. Neuroscience demonstrates that perception and emotional states shape cognitive processing, and psychology establishes that belief systems, such as locus of control, influence life outcomes. Studies on neuroplasticity further reveal that thoughts reshape neural pathways over time.

The idea that these fields may interconnect to shape reality is my own interpretation. While no single study proves this broader relationship, the overlap between them raises fascinating questions. If perception and choice do influence which version of reality we experience, then we may have far more influence in shaping our lives than we realize.

The Final Question

If your brain is starting to hurt, congratulations you made it so far! This perspective does not require mysticism or conspiracy. It does not demand belief in supernatural forces or secret knowledge. It is simply a rational extension of what physics, psychology, and neuroscience already tell us. Every concept discussed, including quantum mechanics, perception-driven reality, neuroplasticity, and the impact of mindset on outcomes, is backed by well-documented studies and established theories.

The possibility that these elements are interconnected, however, is my own interpretation. While research confirms that quantum mechanics governs the microscopic world, and that perception shapes cognition, whether our awareness plays a direct role in shifting between probabilistic life paths remains speculative. 

Still, the overlap is difficult to ignore. If we acknowledge that observation collapses quantum potential, that thoughts rewire the brain, and that belief influences outcomes, then questioning the full scope of our influence on reality is not irrational. It is simply unexplored.

This does not mean that reality bends to our will or that suffering, loss, and failure are illusions. But it does suggest that the way we perceive and interact with the world does alter the probabilities of our future. If the act of observation shapes matter, if thoughts reshape neural pathways, and if belief affects real-world outcomes, then we are not passive spectators in this existence. We are participants.

This idea can be both unsettling and liberating. If reality partly depends on your perception and choices, the life you experience tomorrow may not be fully determined today. Instead, it might depend on how you think, act, and engage with your surroundings right now.

So what version of reality are you stepping into at this very moment?
