The Digital Lie: How 3D Scanners Are Erasing History (And What COSCH Reveals)
We think we're saving history with 3D scans and high-tech cameras. But what if the technology itself is lying to us? This deep dive into the COSCH project—a massive European network of over 200 experts—reveals a shocking truth: our digital preservation tools can actually erase historical fingerprints. From Roman coins that fool modern algorithms to a 14th-century ship slowly collapsing under its own weight, we expose the physics behind the deception. Learn how X-rays uncovered a state-sponsored financial fraud, how infrared light reveals hidden drawings beneath ancient paintings, and why 19 top labs couldn't agree on the color of a simple test card. Featuring insights from leaders like Annabelle Kälka and Lindsay MacDonald, this is a journey into the fragile, messy reality of preserving our past in a digital age.
