<ul><li>Scientists propose that primordial black holes (PBHs) may leave detectable signatures in planets or everyday materials like rocks and metal.</li><li>One possibility is that a PBH trapped inside a planet, moon, or asteroid could consume the liquid core, leaving a hollow shell. These hollow objects could be detected by telescopes by measuring their mass and density.</li><li>Another possibility is that PBHs traveling through solid material could leave behind microscopic tunnels about 0.1 microns thick. Very old materials like ancient rocks or centuries-old metal structures could be examined for these tunnels.</li><li>While the chances of finding these signatures are extremely small, discovering primordial black holes would be groundbreaking and could help solve mysteries in physics, including the nature of dark matter.</li></ul>

Could tiny black holes be hiding in planets or even everyday objects?
