Why Mass Isn’t What You Think — Feynman’s Perspective

Ever wondered what mass really is — and why almost all of your weight has nothing to do with the Higgs field? ⚖️ We feel heavy standing on Earth. Objects resist being pushed. Things have inertia. We casually call all of this “mass.” But here’s the unsettling truth: most of what we experience as weight doesn’t come from the Higgs field at all. So where does mass actually come from? Most people imagine mass as a kind of built-in substance — a fundamental “stuff” that particles simply possess. A number assigned by nature. But that picture is deeply misleading. Just like energy, mass isn’t a single thing with a single source. It’s not an ingredient poured into particles. It’s an emergent property — the result of interactions, motion, and stored energy. The resistance you feel when you push an object isn’t mainly from the Higgs field. And the weight you feel standing on Earth isn’t either. The forward intuition — that mass is something intrinsic and static — is not built into the underlying physics. And that’s the mystery. Physicists discovered that for everyday matter, nearly all of its mass comes from energy locked in motion. Protons and neutrons are made of quarks bound together by gluons, and those gluons are constantly moving at relativistic speeds. If you could somehow “turn off” that motion, almost all the mass would vanish. The Higgs field gives quarks their tiny bare masses — but that accounts for less than 1% of what you weigh. So where does the rest come from? The answer isn’t hidden in particles themselves — it’s hidden in dynamics, binding energy, and relativity. Mass emerges not because matter contains it, but because energy contributes inertia. Not as a substance. As a consequence of motion and interaction. This is where Richard Feynman enters the story. Mass isn’t a thing, he emphasized. It’s a measure — a bookkeeping concept — for how much energy a system has and how stubbornly it resists acceleration. When quarks race around inside a proton, their energy shows up as mass. And systems almost always carry far more energy in motion and binding than in Higgs-generated rest mass. That overwhelming, relativistic contribution — unavoidable and dominant — is what gives everyday objects their weight. Feynman’s genius was to strip away the mystique and say it plainly: The Higgs field allows particles to exist with mass. But it does not explain where most mass comes from. Once you see that, the confusion clears. Objects aren’t heavy because the Higgs field weighs them down. They’re heavy because energy — trapped, moving, and interacting — resists change. Mass isn’t fundamental stuff. It’s an accounting result of energy behaving relativistically. This perspective explains why mass can change with energy. Why heating an object increases its mass (ever so slightly). Why binding energy makes nuclei lighter or heavier. And why “weight” is mostly about forces and interactions — even though the word suggests substance. The universe doesn’t run on mass. The universe is described by it. Ready to rethink one of the most misunderstood ideas in physics? Let’s take it apart — clearly. ⚖️⚡ 💬 QUESTION FOR YOU: What feels more counterintuitive — that most of your mass comes from motion and energy, or that the Higgs field plays only a tiny role in your weight?
