🚨 THE SECOND IS CHANGING


The most accurate clocks we've had are atomic.
They count pulses off cesium atoms.
9,192,631,770 oscillations = 1 second.
But strontium and ytterbium vibrate 100,000x faster.
More ticks per second. Less room for error.
Cesium drifts 1 second every 300 million years.
Optical lattice clocks drift 1 second every 15 billion years.
That's older than the universe.
GPS, financial systems, internet routing all run on atomic time.
And a more precise second means more precise everything.
The second is the foundation of modern civilization.
And we just made it better.
