Show HN: I 3D scanned the interior of the Great Pyramid at Giza
Semi-related, the Great Pyramid was also scanned using muon radiography, by which a "big void" was discovered [0]. Muons can penetrate through a lot of material, so they can see through very large, thick things like the pyramids.<p>Muon tomography was also used to scan the Fukushima reactors [1] and see where the fuel ended up.<p>[0] <a href="https://arxiv.org/pdf/1711.01576.pdf" rel="nofollow">https://arxiv.org/pdf/1711.01576.pdf</a>
