# Claim table — Khafre Pyramid SAR megastructure claim

| Reel claim | Evidence label | Assessment |
|---|---:|---|
| A team claims scans found eight spiral columns and giant chambers beneath Khafre. | Claim/source exists | Supported as a public claim by the Khafre Research Project / Biondi-Malanga-Mei media trail. Not confirmed as archaeology. |
| Four satellite operators returned identical raw tomography data. | Reported claim | WION/Daily Mail-style reports attribute this to Biondi; I did not find independent releases from Umbra, Capella, ICEYE or Cosmo-SkyMed verifying the interpretation. |
| The technology was proved with 100% accuracy in a blind test at Gran Sasso. | Reported claim | Treated as an assertion unless raw protocol/results are public and independently reviewed. |
| Existing shafts could allow physical access without drilling. | Proposal claim | Possible as a proposal, but not evidence the deep structure exists or is accessible. |
| Experts say the claimed depth/interpretation is unsupported. | Independent criticism | Supported by AFP-cited Egyptology/radar experts and Retraction Watch coverage. |
| The 2022 SAR Doppler pyramid paper supports this method. | Weakened/retracted source | The paper is now marked retracted by Remote Sensing; it should not be used as settled support. |
| Hidden spaces in pyramids can be found non-invasively. | Established in other method | True in general: ScanPyramids used muon radiography to find the Khufu Big Void. That does not validate the SAR megastructure claim. |
| Bottom line | Evidence gate | Interesting lead, not confirmed discovery. Needs raw data, methods/code, independent replication, official Egyptian permission/status, and field/geophysical confirmation. |
