Abstract The intensity behaviour of gravitationally focused (de‐focused) scalar massive matter φ( x ϱ) generating the focusing (defocusing) spacetime via Einstein's equation is investigated in different collapse regions (weak collapse, strong and weak dynamical collapse domain in the region of strong collapse). The dynamical collapse of, in general, non‐geodesic moving matter φ is braked by de‐focusing effects inherent in field theoretic description. If the intensity is greater than definite bounds at significant states, the collapsing matter φ cannot be stopped by de‐focusing caustic diffraction before singular states of matter φ and curvature R μv are reached; this singularities could be related to the notion physical singularity.
