Abstract We study the energy issue in critical collapse. It is found that collapse, contribution from material greater than gravitational energy. The quantity m / r plays an important role identifying formation of apparent horizon where Misner–Sharp mass and areal radius. observe maximum value fluctuates between 2/15 4/15. This denotes a large gap collapse black hole for which criterion = 1/2.
