On campus I had a lecturer who would fill three boards with equations, stop, and say, "and this is why the bridge won't fall." I remember sitting there thinking: how does scribbling on a board know anything about concrete?

I filed it away. Engineers do that. You pass the course and move on.

Then recently I was watching a documentary on how Neptune was discovered, and the question came back with teeth.

In 1846 a French mathematician named Le Verrier noticed Uranus was wobbling in a way Newton's equations didn't predict. So he sat at a desk, did the arithmetic, and told astronomers exactly where to point a telescope. They pointed it. Neptune was there. A planet nobody had ever seen was found with a pencil.

𝗧𝗵𝗮𝘁 𝘀𝗵𝗼𝘂𝗹𝗱 𝗻𝗼𝘁 𝘄𝗼𝗿𝗸. And it keeps working.

Maxwell wrote four equations about electricity and magnetism in the 1860s. The maths said invisible waves should exist travelling at the speed of light. Nobody had seen one. Twenty years later Hertz built a machine and there they were. Every phone call you make rides on waves a man found in algebra before anyone found them in the air.

Dirac wrote an equation in 1928 that only balanced if there was a particle like the electron with opposite charge. He didn't want it to be true. It looked like a mistake. Four years later antimatter was detected in a cloud chamber.

Einstein's equations predicted ripples in spacetime in 1916. We detected them in 2015. The universe honoured a hundred-year-old piece of paper.

Here is the question that nobody, believer or atheist, has a comfortable answer for.

Mathematics happens inside human heads. Galaxies do not care what happens inside human heads. Yet the symbols we invent on Tuesday describe stars that collapsed before Tuesday existed. If the cosmos were random, there is no reason the notebook and the nebula should agree. They agree with terrifying precision.

Einstein felt it. "The most incomprehensible thing about the universe is that it is comprehensible." The physicist Eugene Wigner wrote a whole paper about it and could only call it "the unreasonable effectiveness of mathematics." Unreasonable. His word. A Nobel laureate admitting the foundation of his field is a mystery he cannot justify.

Think about what you do every time you trust an equation. You are assuming the universe is rational all the way down. That it is built on logic. That it was, in some sense, written.

Nobody believes a book wrote itself just because the grammar is consistent. Consistency is the fingerprint of an author.

John opened his gospel with a Greek word that every philosopher in his day knew. "In the beginning was the Logos." Logos: word, reason, ratio, the underlying logic of things. "All things were made by him; and without him was not any thing made that was made." John 1:1-3

That is not a religious slogan. It is the only hypothesis on the table that predicts what Le Verrier found. If the universe was spoken by a Mind, then of course minds can read it. We are reading the handwriting of the One who made both the stars and the eyes.

So the next time an equation on a board turns out to be true in the sky, pause before you move on.

You just watched the universe behave like a sentence.

Sentences have speakers.
