Secrets Behind the Stones

Three very different tools, working without a single drill, reshaped what we know about the world's most famous tomb:

• Muon tomography found a thirty-meter void above the Grand Gallery in 2017
• A robot camera met a sealed door with copper handles deep in a Queen's Chamber shaft
• Thermal scanning flagged unexplained heat patches on the eastern face

Each new clue widens the gap between curiosity and caution: the more we want to look inside, the more carefully we must protect what we are looking at.
