I had this strange thought experiment the other day.
Imagine this: every living species in the universe—humans, animals, birds, insects, even whatever life might exist far away in space—closes their eyes at the exact same time.
No one watching. No one observing. Just silence.
The big question is—would the world vanish in that moment? And if we opened our eyes again, would we still see the same world… or a completely different one?
Why This Even Makes Sense (Quantum Side of Things)
Quantum mechanics says something very weird: particles don’t exist in a fixed state until they are observed. Until then, they exist in many possible states at once. This is called superposition.
Normally, we laugh about it with “Schrödinger’s cat”—alive and dead at the same time until someone opens the box. But what if it’s not just a cat? What if it’s the whole universe?
The Eye-Closing Experiment
So imagine it really happens. Every consciousness shuts off vision at once.
No human. No animal. No alien. No witness.
In that instant, maybe the universe slips back into that “probability haze.” Mountains and rivers lose their shape. Stars stop burning. History rewinds. The world un-exists.
And then we open our eyes again.
The universe reappears—but maybe not the same one. Maybe the sky is not blue anymore. Maybe the person you loved never existed here. Maybe you are in a version of reality you don’t even recognize.
Every blink becomes a roll of the dice.
But Science Doesn’t Agree So Easily
Of course, physics doesn’t let us dream so wildly. According to current science, the universe doesn’t need us to exist. Atoms and photons keep interacting with each other. Gravity keeps pulling. Light keeps bouncing.
Even if nobody looks at the Moon, it’s still there—because the universe is always “measuring” itself. This idea is called decoherence.
So by this logic, closing all eyes changes nothing. When we open them again, we’ll see the same world.
Still, the Mystery Remains…
And yet, I can’t shake off the thought. What if consciousness is more than just a passive witness? What if we are not only seeing reality but also anchoring it?
It’s one of those questions where science gives you one answer, but your imagination whispers another.
Final Thought
Maybe the universe doesn’t vanish when we blink. Maybe it’s not that fragile.
But maybe, just maybe, every time we close our eyes, the universe does hold its breath for a moment—waiting for us to look again.
