Professor Rovelli has an wonderful creativity.It is important like the imagination.We search after all answers and all ideas are of course welcome.I am not a big supporter of whormholes but I respect these mathematical mirrors.In fact that can permit to better understand our Black holes.A BH for me is a spherical volumes of matter not baryonic cold in logic.This mass not baryonic has properties and rules Inside this universe.They embark the galaxies these supermassive BHs central to galaxies.They recycle alos probably informations, they produce probably also this matter not baryonic named the dark matter.They permit also the rotation in logic around this universal cosmological singularity ,the central BH,the biggest sphere producing in logic this gravitational aether in producing the speedest particles of gravitation, the main primordial codes, the main primordial field ,gravitational.
The mathematical plays become relevant even if sometimes the subjectivity is taken into account instead of our objectivity.After all the imagination and the convergences are fascinating.
I liked all this reasoning ,the maths implies an ocean of possibilities, and the sortings, synchros become keys of understanding.
A beautiful creative reasoning Professor Rovelli,regards
