We love a genius. Albert Einstein? Synonymous with the word itself. Relativity, photoelectric effect, gravitational waves—he rewrote the rules of space, time, and gravity.
But here’s the thing. Geniuses bleed errors just like the rest of us. In fact, sometimes their biggest blunders are just as famous as their hits.
“For sure, he was wrong about tons ofthings,” said Nicolás Yunes, a theorist at UIUC. He’s not insulting Einstein’s legacy, mind you. It’s just that history loves the hits and ignores the miss notes. We remember what shook the world. The things that got us wrong? Mostly forgotten. Or corrected quietly in the margins of physics journals.
The Math That Broke
Take gravitational waves. In 1917, Einstein got them right in his head. Matter accelerating ripples space-time. Simple enough conceptually. Then he tried to prove it with math alongside Nathan Rosen.
It failed. Hard.
The equations didn’t just wobble—they exploded. Singularities everywhere. “They diverge,” Yunes says. “They can’t represent reality.” So Einstein did what any sensible physicist would do: he changed his mind. Gravitational waves couldn’t exist.
He published this conclusion in Physical Review.
The journal sent the paper to an anonymous reviewer. The reviewer caught an error. A massive one. Einstein wasn’t dealing with a physical impossibility but a coordinate artifact. Think of the North Pole. Lines of longitude meet there. Does a singularity exist in your living room? No. You just need a different map.
Einstein found out his paper was being critiqued. He flew off the handle. Withdrew the manuscript entirely. Submitted it elsewhere.
Meanwhile, the anonymous reviewer (who turned out to be Hermann Weyl, though that’s beside the point) befriended Einstein’s assistant. Explained the error gently. Einstein eventually realized the mistake. Republished. Same waves. Different math. This time, the conclusion flipped. Waves were real.
The Black Hole Denial
He made the same mistake twice. That’s embarrassing even for a legend.
Einstein looked at the math for black holes and saw the same “impossible infinities.” Same result. No such object exists. He stuck to this guns blazing while everyone else began to suspect spacetime curvature could indeed trap light forever.
John Norton, a philosophy professor at Pitt, noted that Einstein remained resolutely skeptical. He believed the singularity at the event horizon was real physics, not just bad coordinates.
Was this stubbornness? Partially. But also philosophy.
Norton suggests it was deeper. Einstein believed physics and math had to dance a certain way. When others showed those infinities were artifacts of his preferred coordinate system, he wasn’t convinced.
“He was unmoved,” Norton wrote.
Maybe because the idea felt wrong on a visceral level. Or maybe because changing the map felt like changing reality itself. Either way, he ignored the evidence piling up.
Quantum Spookiness
Now for the big one. Quantum mechanics.
Einstein hated it. Not the results, which were robust and experimentally verified. The nature of it. Specifically entanglement.
Two particles, linked across distances. Measure one, and the other snaps into place instantly. Faster than light. Einstein called this “spooky action at a distance.” He wrote to Max Born in 1947 saying he couldn’t believe in a theory that relied on ghosts. He wanted local reality. Cause here affects effect here. No jumping around the universe.
He thought quantum mechanics was incomplete. Just a placeholder for a deeper truth. A truth that would bring order back.
He was wrong about that, too.
In 1964—nearly a decade after Einstein died—John Bell proved the math. Entanglement is real. The spookiness isn’t a glitch. It’s a feature.
“It’s still incompatible with general relativity.”
Today, Yunes points out that our phones and laptops rely on quantum mechanics. So that part? Settled. Einstein’s classical theory of gravity remains brilliant, but it doesn’t mesh with the quantum world.
Where does this leave us? In a black hole, for example. The center is small enough for quantum effects yet massive enough for relativistic gravity. Both theories crash into singularities there. Neither can explain what happens.
Maybe general relativity needs fixing. Maybe quantum mechanics needs expanding at those extreme scales. Who knows.
The Joy of Error
Here is the twist. None of these errors stopped him from changing everything.
General relativity started from assumptions Einstein later abandoned. He based it on extending relativity to acceleration. On Mach’s principle. Turns out? Neither fits the final theory neatly. The result stands anyway. The path was messy, but the destination was new physics.
Einstein knew his reputation wasn’t flawless. He laughed about it, actually. Writing with Leopold Infeld once, Infeld noted the importance of getting details right because of the big name on the cover. Einstein just laughed.
“There are incorrect papers under my name,” he said.
Fair point. Science isn’t about being right. It’s about correcting the people who were wrong yesterday. Including him. Including us.
What does he get wrong tomorrow? Probably something we haven’t discovered yet.
