Feliks Zemdegssolved his 5×5 cube at Melbourne Cube Day in 44.837 seconds . And the crowd went not at all idle .

The 5×5 Rubik ’s cube — or Professor ’s cube — has over 282 trevigintillion ( 10 ^ 72 ) permutations , and requires intimate noesis of the solving algorithmic rule for both the 3×3 and 4×4 . Even thetutorialfor resolve one of these complicated toys is over 40 arcminute long . Because of all the moving part , a Professor is also much more delicate than the run - of - the - pulverization Rubik’s — just follow how much more gingerlythis guytreats his bigger cubes . Long history short , it ’s really , really difficult . Why was no one else in the room impressed ?

Zemdegs , an Australian , broke the previous world track record of 46.97 hold by … himself . In fact , Felix has moderate onto and slowly whittled away at his own criminal record for the Professor since 2009 , when he twist the deed away from the comparatively molasses - fingeredDan Cohen , who clocked 1:07.25 as his best .

perhaps everyone else at Melbourne Cube Day was too engaged solving their own puzzler , or maybe watching Zemdegs win was simply the first moment ( “ Oh great , this guy rope again ” ) . Either path , it ’s a remarkable exploit of teaser solving not soon to be flummox , except maybe by Feliks himself .
