299846604 The Natural Speed of Light. The Geometric Truth - David Charlie Charles;David Paul Charles

299,846,604 metres per second.

Not 299,792,458. That is the number physics has measured for three hundred and fifty years, fixed by international committee, frozen into the SI definition, taught in every classroom on Earth.

It is wrong by 0.018 per cent.

Not because the measurements were sloppy - they were extraordinary. Not because the physicists were careless - they were brilliant. The number is wrong because the second they used to measure it was inherited from a Babylonian division of the day made four thousand years ago, by people who had never heard of hydrogen.

The hydrogen atom does not care what the Babylonians chose. It does not care what the international committee agreed. It produces its own number, in its own units, and has been producing it for fourteen billion years.

This book derives that number from pure geometry - from four nested circles built outward from the simplest atom in the universe. No clock. No second. No measurement of time at any stage. The proof is constructive. Every step is shown. The reader is invited to check each one.

What emerges is not just the speed of light, but Planck's constant, Einstein's second postulate as a theorem rather than an assumption, and the geometric meaning of E = mc².

None of which requires new physics. All of which follows from the geometry of the simplest atom, performed with the tools of classical Euclidean construction, by a method that any high school student can check.

Hydrogen knew all along.
