When Reality Is Not Solid

Sometimes I wonder if reality is really as solid as the chair I sit on, or if it is something far more strange and fragile beneath the surface. The first time I seriously think about this was not in a classroom, but alone at night, watching a video about quantum physics. I did not expect that simple curiosity would slowly change the way I see the world, science, and even myself.

I still remember the first time I feel confused but also excited about quantum physics. It was not from university or formal class. I just watching random video late night, and suddenly someone explain about quantum superposition and double slit experiment. At that moment I stop the video and just staring at the wall. I feel like… wait, what? Reality is not solid?

Before that, physics for me is simple. Object fall because gravity. Light move straight. Cause and effect. Clear. But when I hear about particle can be wave and particle same time, honestly my brain refuse it first. It feel like science fiction, not real science. But then I start read more, search more, and slowly I realize this is not imagination. This is real experiment.

For example, the double slit experiment show that particle like electron can behave different when observed and when not observed. This idea disturb me deeply. Because if observation change outcome, then what is reality actually? Is reality independent from us, or we are part of equation? I know many physicist explain this carefully, and it not mean “mind create reality” in mystical way. But still, it shake something inside me.

Neils Bohr (Wikipedia)
I read about Niels Bohr and his Copenhagen interpretation. He basically say that we cannot talk about reality without measurement. Then I also find idea from Albert Einstein who not comfortable with this randomness. He say, “God does not play dice.” When I read that, I feel little relief. Because Einstein also confused and disagree. So I not alone.
Later I discover Richard Feynman who said, “I think I can safely say that nobody understands quantum mechanics.” This quote hit me hard. Because if genius like him say nobody understand fully, then maybe it is okay if I also confused.
But the more I read, the more I feel something strange but beautiful. Quantum physics is not only about particle. It is about limitation of human knowledge. It show that nature at very small scale does not follow our everyday intuition. And maybe that is okay. Universe not designed to fit human logic.

I remember one night I try explain superposition to my friend. Halfway talking, I realize I also not really understand it completely. We both laugh. But inside me I feel something growing — curiosity. Not to “control” reality, but to accept that reality is deeper than what we see.
Some physicist like Werner Heisenberg talk about uncertainty principle. It say we cannot know position and momentum exactly same time. When I first read this, I feel uncomfortable. As someone who like engineering and structure, I like certainty. I like numbers clear. But quantum world say: no, there is fundamental uncertainty.
Maybe that is why quantum physics attract me. It humble me. It remind me that even strongest theory still leave mystery. It teach me that doubt is not weakness, but part of science.
Sometimes I sit alone and think — if reality at small scale is probability wave, then what about our life decisions? Of course this is metaphor, not literal physics. But still, it make me reflect. Maybe life also not binary. Maybe many possibility exist until we choose.
I know my understanding still very limited. I am not physicist. I just someone curious. But quantum physics change how I see certainty, control, and knowledge. It make me more open to complexity.
And maybe that is the most powerful thing science can do — not give comfort, but expand our mind even when it feel uncomfortable.

And maybe in the end, quantum physics is not about finding final answers, but learning how to live with deeper questions. It teach me that reality is not always simple, not always fixed, and not always fully understandable. But instead of making me afraid, it make me more curious. And maybe that curiosity — even with imperfect understanding and broken English — is already a small step closer to truth.
