Hawking argues that information is destroyed

node

In a Physical Review D paper on the breakdown of predictability in gravitational collapse, Hawking drew out the consequence of his own 1974 result: because the emitted radiation is thermal and depends only on mass, spin and charge, the correlations that would let the initial state be reconstructed do not survive evaporation. That conflicts with the unitarity of quantum mechanics. The paper converted black holes from an astrophysical topic into a foundational problem in physics, and the conflict it identified has not been resolved.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
