Bang!
Astronomers suspect that in the first second after the universe formed, the very first black holes also formed. These tiny though profoundly dense objects — think of an atom-sized particle wielding the mass of a mountain — are dubbed “primordial black holes.” But there’s a problem: There’s still no evidence they’ve ever existed.
Now, scientists have proposed a novel idea: Perhaps the proof is in front of us, here on Earth.
In new research published in the journal Physics of the Dark Universe, researchers conclude the ancient objects could have left observable proof in the form of microscopic tunnels, or even in hollowed-out objects beyond our planet like asteroids. Though the chance of finding micro-tunnels on Earth is likely small, they may be present in places around us, like the rocks, glass, and metal of buildings — particularly old buildings.
