Hi Carol While I accepted the article's slant, it crossed my mind (again) that mainstream science has a history of making complacent assumptions and over-valuing modern human achievements; causing misapprehensions which sometimes persist for generations. Maybe some large or small phenomena now classed as 'natural' - even big stuff like quasars, magnetars etc. - might be higher Kardashev civilizations' engineering or power generation works?
