Explanation for Ball Through the Stumps

[Yaseen Dadabhay]

but wouldnt a cricket ball be able to create enough energy , given that a
spin bowler bowls at 90kmh+ and medium to fast bowlers at an average of
120-150kmh.How much energy would a ball of this speed create ?

Actually that is what is unusual about the theory that something that does not
have enough (in the classical sense) energy would still tunnel through.

If you include kinetic energy, it might even exceed E=mc^2.

Well if it was his googly it's probably the consistantly biggest spinning ball
I've seen.
