Hypothetical Extreme Spacetime Disconnect and Cosmic Expansion Abstract imagine a exrtreme curvature event in 3d where spacetime is curved too much in that certain region of that blackholes or huge mass body . then due to that extreame curvature event the spacetime region may cutted down . like if u put too much force on a rope it get cut . like that spacetime will also get cut and it will seprated from the region of blackholes from each of the direction but the local area of black holes may still feel the gravitational pull of that blackholes . As the curving force of cut down spacetime get a force after cut down it will start to expand . that's how it works . this events may occur in every region of universe for huge curvature events on the universe . the expansion of spacetime comes after fully disconnection of the spacetime from a huge curvature zone and start to expanding with stress released velocity but the local region of that high curvature zone of the objects still pull the local zone by it's gravity .the nearby zone of event horizon still get affected by the spacetime curvature of blackholes but the outer edge of the space fabric of blackholes starts to expands as it get causally disconnected after the huge gravitational or curvature pull. so the outer zone get cut and the inner zone of blackholes still get gravitationally activated pull but the outer edge of spacetime zone which get cut starts to expand with the stress energy that it got after the disconnection . The disconnection doesn't form in the core of blackholes rather it is disconnection of the outer edge spacetime of the blackholes
