Price also made pioneering numerical simulations which established (nonrigorously) a precise scenario for the emission of gravitational radiation during the merger of two compact objects (such as two black holes).
Price foretog også grundlæggende numeriske simulationer, som beskrev et præcist scenarie for udsendelse af gravitationsstråling ved sammensmeltning af to kompakte objekter (som f.eks. to sorte huller).
