Are You Creating Reality Just by Looking at It? What is the Double Slit Experiment?

Imagine walking into a dark room and flipping on the light. Instantly, the space is illuminated, objects come into view, and suddenly, reality seems to exist where there was once only darkness. Now, what if the universe works the same way?
What if, at the most fundamental level, reality itself doesn’t “exist” until you observe it?
This isn’t just philosophy or science fiction—it’s one of the most mind-bending discoveries in quantum physics.
It’s called the Double-Slit Experiment, and it suggests that the way you observe reality literally changes it.

The Experiment That Broke Reality
Scientists wanted to understand how particles—tiny bits of matter—would behave when shot through a barrier with two slits.
They expected one of two outcomes:
If particles behaved like tiny solid objects, they would go through one slit or the other, forming two lines on the screen behind the slits.
If they behaved like waves, they would spread out, go through both slits at once, and create an interference pattern—multiple overlapping lines on the screen.
So, they fired electrons (tiny pieces of matter) at the slits, expecting them to behave like little bullets.
But what happened shocked everyone.
Instead of forming two neat lines, the electrons created a wave-like interference pattern.
They weren’t behaving like particles—they were behaving like waves of possibility, spreading out and going through both slits at the same time.
It was as if the electrons didn’t decide where to be until they hit the back screen.
Reality wasn’t fixed—it was uncertain, fluid, undefined.
But then, scientists did something even stranger.
The Moment Reality Changed
They placed a measuring device at the slits to observe which slit the electrons passed through.
The moment they did this, everything changed.
The electrons stopped acting like waves and started behaving like little particles again—forming two clean lines, just as expected.
In other words, the act of observing them changed their behavior.
Somehow, the electrons knew they were being watched and adjusted accordingly.
This single experiment broke reality as we know it.
It suggested that particles exist in a state of possibility until they are observed—only then do they "choose" where to be.
What This Means for Reality
The implications of the Double-Slit Experiment are huge.
It suggests that:
Reality isn’t solid and fixed—it’s fluid until observed.
The act of looking at something changes what it is.
Consciousness (your awareness) may play a role in shaping the physical world.
If particles don’t “decide” where to be until we look at them, then what about everything else?
Could it mean that your focus, your thoughts, and your attention literally shape the world around you?

Does Reality Exist When You're Not Looking?
The Double-Slit Experiment suggests that reality exists as waves of probability until observed.
So does that mean…
Your house disappears when you’re not looking?
Your job stops existing when you go home?
The world only continues because other people are observing it?
Let’s break it down.
Is My House Still There When I’m Not Looking?
Short answer: Yes, but not in the way you think.
If the quantum world follows the same rules as the Double-Slit Experiment, your house is not necessarily sitting there in a fixed, solid state when you’re not perceiving it.
Instead, it exists in a state of potential—an informational field of probability—until an observer collapses it into a specific experience.
This doesn’t mean your house disappears. It just means that its exact, definite state is unknown until someone interacts with it.
When you return home, your observation “collapses” the possibilities into a defined experience of your home.
But here’s the big question: If you’re not looking at your house, what keeps it there?

Does Reality Stay "Real" Because Other People Are Observing It?
One possibility is that reality persists because other people are observing it.
Quantum mechanics suggests that the act of observation affects the state of a particle.
If this principle applies to everything, then objects might only maintain a stable form because collective consciousness is holding them in place.
In other words, when you’re at work, your house still exists because other people (your neighbors, a passing bird, a security camera) are interacting with it in some way.
But if no one—human or otherwise—was observing it at all?
Quantum theory suggests that it may exist in a more fluid, undefined state.
Does My Job Exist When I Go Home?
Your job, your workplace, and even your co-workers exist in the same way—as potential until observed.
When you leave work, the exact details of your desk, the conversations happening in the breakroom, or even the placement of objects may not exist in a fixed state.
Then, when you return, you re-engage with that environment, collapsing it into a stable reality based on your expectations, past experiences, and observations.
Think of it like a video game—when you’re in one location, the rest of the game world isn’t “loaded” in full detail. Instead, it exists as a framework of possibilities that only materializes when you interact with it.

What Does This Mean for Everyday Life?
If reality is shaped by observation, then our perception plays a huge role in how the world unfolds around us.
Your Attention Shapes Your Experience. If quantum reality exists as possibilities until observed, then what you focus on in life becomes more “real” to you.
Focus on fear, and fear becomes your reality.
Focus on abundance, and you’ll find more of it.
Focus on gratitude, and life will reflect it back to you.
Your Expectations May Influence the Physical World. In the Double-Slit Experiment, particles behaved differently when observed. Could this mean that our expectations and beliefs subtly shape what happens in our lives?
Reality Is More Flexible Than We Think. If things exist in states of possibility until observed, then perhaps we have more power than we realize to shape our own experiences—by shifting our focus, beliefs, and level of awareness.
Your Presence Matters. The simple act of being aware and engaged with your surroundings might have a direct impact on how reality unfolds around you.
Are You Just Watching Life, or Creating It?
If the Double-Slit Experiment tells us anything, it’s that consciousness and observation influence reality in ways we don’t fully understand.
If reality responds to awareness, then what happens when we shift how we see the world?
What happens when we stop being passive observers…
And start consciously creating?
