James' World 2

Inside every rechargeable battery—in electric cars and phones and robot vacuums—lurks a cosmic mystery. The lithium that we use to power much of our lives these days is so common as to seem almost prosaic. But this element turns out to be a wild card, a rebel that’s been challenging our most basic understanding of the formation of the universe itself. 

Beyond the lithium ion-powered batteries, beyond the glass and ceramic manufacture, optical systems, air purification, fireworks and rocket propellants, nuclear weapons, and mood stabilizing pills, lithium is cast about the cosmos. But there is not nearly as much of it out there as there should be. And we don’t know why. 

This wily little element has defied explanation for generations, refusing to obey the rest of our cosmological orthodoxy. The robust Big Bang theory, among other accomplishments, allows us to precisely predict the abundances of all of the light elements across the universe.

Except lithium.

Which means there might be something wrong with our understanding of the Big Bang. There might be something wrong with our measurements. There might be something wrong with both. Or this might be a signal that there are new, as-yet undiscovered forces that were at work in the early universe. Whatever the solution is, this rebel and its so-called “cosmological lithium problem” are here to teach us a radical new fact about the universe.

We just have to figure it out.

Here on Earth, lithium had laid underfoot since the planet’s formation, with nobody suspecting that the element even existed. Taken from the Greek word for “rock,” on Earth, lithium is usually only found in trace amounts in larger mineral conglomerations. In 1800, the Brazilian chemist José Bonifácio de Andrada e Silva discovered it as a new ore on the island of Uto, Sweden. Seventeen years later, the chemist Jöns Jakob Berzelius isolated the new element within the ore. Since then, the silvery-white metal has found itself making possible so many of our contemporary luxuries.

But most of the universe’s lithium is bound up inside of stars.
