Namely: A trapped surface forces all rays to point towards a centre, regardless of whether the surface curves outwards or inwards. Using trapped surfaces, Penrose was able to prove that a black hole always hides a singularity. So I tried to understand this quote by the means of Blender 4, Gimp3 and my idea seems to be: ^^^ upperwise picture with normals of 2 directions showing this way energy disappears. But with normals pointing towards center only there must be the blast of energy without her red opponent like on my picture which is red darkness as opposition towards blue lightness. My question is: How can same space and time lose specularity of light? Its phase of wave must become a line or vector with one directional normal. The light loses specularity via wave lining towards flat vector _ | _ and not () Source: https://www.nobelprize.org/prizes/physics/2020/popular-information/
