Lived from 1858 to 1947, aged 89.

Max Planck

Max Planck didn’t seek to overturn classical physics. He ran into its limits. By taking experimental results seriously and refusing to force certainty where it no longer fit, Planck revealed one of science’s deepest lessons: progress often begins when explanation must stop.

History

Quote

“It was an act of despair, to sacrifice physics for the sake of finding an explanation.”

Max Planck
circa 1900

Planck Constant

A later reflection by Planck about the year.

Planck didn’t advance physics by defending what he believed, but by surrendering it when the evidence refused to cooperate. His “act of despair” reminds us that truth doesn’t yield to confidence. It yields to honesty—especially at the moment when our most trusted explanations stop working.

FAQ

Is space truly empty? Anywhere?

Space

“Empty space” is a convenient shorthand, not a physical reality. Even where atoms are scarce, gravity still acts, light still travels, and particles like neutrinos pass through. The universe has no true voids—only regions where matter is spread astonishingly thin. Emptiness, it turns out, is relative.

Empirical Metaphysics

Forces, fields, and fundamental law.

Physics studies the deepest measurable structures of reality — matter, energy, space, and time. It asks not only how things move, but what they are. From quantum fields to gravitational curvature, physics bridges the gap between what exists and how we describe it. It is metaphysics disciplined by experiment.
