Which is interesting but perhaps less interesting than our universe rubbing up against a parallel universe in the multi-verse, or our universe bumping
into the future expanded universe meaning we are running out of room to expand into (nasty one that one) or, inter-dimensional cross-talk,
hype-dimensional (sp) time-line convergence.
Sound wave lensing, um, sound reflection, magnetic resonance amplification of the excited magnetosphere, and the trash compactor on the
space-station.
