It the past, a massive once-a-century solar storm could pass without incident, but now it could knock out the electrical grid, communication systems and satellites. Solar storms in Quebec, Canada in 1989 and in and Malmö, Sweden in 2003 knocked-out electricity grids. However, geologists at Lund University in Sweden have uncovered more evidence for a massive solar storm in the distant past. “If that solar storm had occurred today, it could have had severe effects on our high-tech society", says Raimund Muscheler, professor of geology at Lund University, who previously detected evidence of massive solar storms in 775 and 994 CE. In separate research, mathematicians think they’ve proved that massive solar storms are more unlikely than previously thought.
