Scientists are mapping Earth's hidden interior with 'ghost particles'

Every second, trillions of geoneutrinos — near-massless particles born from radioactive decay deep inside the planet — stream through your body and the entire Earth without touching a thing.

Every second, trillions of geoneutrinos — near-massless particles born from radioactive decay deep inside the planet — stream through your body and the entire Earth without touching a thing. Now, as Wired reported Oct 4, physicists are catching a handful of them in giant underground detectors and using them to build a brand-new map of Earth's volatile interior — imaging the planet's core with particles older than human civilization. The true-strange part: we can't drill there (the deepest hole ever is about 12 km; the core is 2,900 km down), so the only "camera" that reaches it is one made of ghost particles.

Verified science from published detector research, not speculation.
