Opposing ideas can be symbiotic because each side sustains attention on the other—ongoing debate prevents consensus and keeps both ideas circulating longer.
Adding a tiny, controlled oxygen partial pressure extends mirror lifetime because oxygen reacts with or alters surface chemistry of damaging species, preventing or reversing collector-coating degradation and reducing maintenance frequency.
