Astrophysicist evaluates the physics in Project Hail Mary — centrifugal gravity and orbital mechanics fare well, astrophage does not
Northeastern University astrophysicist Jacqueline McCleary reviews the scientific accuracy of the film. She approves of the centrifugal gravity system and how orbital mechanics are handled, but notes the astrophage concept falls apart at scale — the energy a microorganism could store is orders of magnitude below what the sun outputs. She also touches on why the film's depiction of Rocky as a completely alien biology may actually be more scientifically grounded than most sci-fi creatures.
