The NFL’s commissioner and chief negotiator, Roger Goodell, the guy reviled by Tom Brady and network television CEOs alike, made a salary of nearly $32 million in 2015, not including his massive expense account. With the big money dangling like a gold ring on a carousel, you would think nothing could stop kids from wanting to reach for that ring.

In 1859, Richard C. Carrington, a British astronomer, observed and recorded a major geomagnetic solar storm that produced a white light flare. The next day, "auroras could be seen in tropical latitudes and telegraph systems all over the world, starting to shock telegraph operators, operating while unplugged, and igniting the telegraph paper," according to a recent public interest report by the Federation of American Scientists. The author of the report, Robert Coker, a former aerospace engineer for NASA Marshall Space Flight Center, says solar flares are known to have detrimental effects on satellite operations, GPS systems, hi-frequency airplane communications, navigation, and for good measure, the electrical power grid. Coker calls sun flares and other electromagnetic disruptions space weather events. Minor events occur almost yearly, he says, resulting in GPS disruptions and rerouting of aircraft. More significant events occur once a decade, with extended local outag
