Try this right now.
Put your hand on a table.
Feels solid, right? Obvious. Undeniable.
Except… you didn’t actually touch it.
That sounds like clickbait, but it’s not philosophy, and it’s not wordplay. It’s straight-up physics.
The Illusion of Contact
On the smallest scales, matter is mostly empty space. Atoms are made of a tiny nucleus surrounded by electrons buzzing around in probability clouds. And here’s the key part:
Electrons don’t like each other.
When your hand approaches the table, the electrons in your skin repel the electrons in the table through the electromagnetic force. That repulsion creates resistance, and your nerves interpret that resistance as the sensation of touch.
So what you’re feeling isn’t contact—it’s force.
So Why Does Everything Feel Solid?
Because your brain is extremely good at lying to you.
Evolution didn’t care about accuracy—it cared about survival. If your ancestors had to consciously think, “I am currently experiencing electron repulsion mediated by quantum fields,” they wouldn’t have lasted very long.
Instead, your brain compresses all of that complexity into one simple story:
“Solid object. Don’t walk through it.”
That story works so well that we forget it is a story.
Solidity Is a Collective Agreement
Zoom out, and “solid” stops being a property of matter and starts being a behavior.
That’s why:
-
Glass is solid but transparent
-
Steel is solid but bendable
-
And air feels like nothing… until you’re falling through it at 200 mph
You Are a Walking Field Interaction
Right now, your body is:
-
exchanging forces with the floor
-
exchanging photons with the room
-
exchanging air molecules with your lungs
At no point does “contact” actually happen.
You are a pattern of forces, interacting with other patterns of forces, in a universe where emptiness vastly outnumbers matter.
The Mind-Blowing Part
This means your entire physical reality—the feeling of keys, cups, skin, walls—is not how the universe is…
…it’s how your brain makes sense of it.
And somehow, that interface convinces you that invisible force fields feel like solid objects.
Which might be the most impressive trick your brain pulls off every single second.
