Thermal Anisotropy and Interstellar Tunnels in the Local Bubble: A Topological Reading from the DQ Framework

Recent observations from the eROSITA X-ray telescope have revealed an unexpectedly complex
structure in the Local Hot Bubble (LHB), the tenuous plasma environment surrounding our Solar
System. The study, led by the Max Planck Institute for Extraterrestrial Physics (MPE), confirms the
existence of a large-scale temperature gradient and an ”interstellar tunnel” connecting our bubble
with the neighboring superbubble in the direction of Centaurus. In this work, we interpret these
findings under the Quantum Diffusion (DQ) framework. We propose that thermal anisotropies and
gas tunnels are not mere hydrodynamic accidents, but act as baryonic tracers of high-diffusivity
channels in the underlying informational substrate. The ”Bubble” is thus reinterpreted as a domain
of low information density where the subspace metric facilitates transport, validating the hypothesis
that the vacuum is structured by entropic gradients.
