Claim 3: “transfers it onto the forming a compact, superheated accretion disk with a comparable size to Saturn, and heated to temperatures far above those found on the surface of the sun.”

SINGLE SOURCE

The provided evidence for claim 5 consists of general definitions of mass and unrelated YouTube/government links. There is no specific evidence regarding the accretion disk size or temperature for the ATLAS system.
