Not sure how the 1859 Carrington Solar Event could have caused "worldwide power outages", seeing as how widespread power usage came years later. Maybe the author was referring to electrical effects on telegraph systems, which did occur?Makes you wonder about the rest of the article, and wonder why editors don't do some basic fact checking.
Because they're editors.
Or rather - because they're no longer editors, not in the usual sense of the word. Otherwise we wouldn't be getting so many poorly fact-checked and poorly spell-checked articles.
