Improvisation beneath the horizon: quantum bounce turns a black hole into a white hole ✦
A black hole need not die in a singularity — inside it could lurk a quantum bounce, turning collapse into a white hole. Spacetime there resembles a jazz improvisation without a conductor: one coordinate becomes a clock, and uncertainty prevents the area from going to zero. This is not just mathematics — such bounces could leave traces in gravitational waves, blurring the line between black and white.
🎯 The clock inside a black hole is one of the spatial coordinates. Usually, time flows from the horizon to the center, but in relational quantum mechanics, the role of time is taken by the variable b, describing the 'radius' of invisible cylinders. Classically, it squeezes to a point, but quantumly, it bounces, as if hitting an elastic quantum cushion.
🎬 The idea of a black hole turning into a white hole echoes the 'tunnels' from Stanisław Lem's 'Fiasco' and the timeless dimension of 'Interstellar', but here there are no wormholes — only a fundamental quantum bounce of the very fabric of reality.
