My brother claims that sunspots can send off flares and 'fry' us, as he puts it. This is kind of scary. I'm not the most knowledgable person when it comes to these things. I thought maybe some of you experts could tell me what these big spots mean and what they could do to us. I've gone years and years without knowing of their existence, and all of a sudden I'm being bombarded by people talking about space storms and protons, and death rays basically.
Would someone be so kind as to educate me in layman's speak about what happens when earth is hit by a big solar flare? I have two kids and I'm getting kind of depressed about our possible imminent incineration.
