... No.
If we survive another 600 billion years, I'd expect that we'd be more concerned with entropy killing us all than anything else. You're also wrong about the poles flipping. IIRC, we're actually supposed to be a couple million years
late. Not only that, but the earth's poles flipping won't have any influence on the sun's tendency to produce solar flares. Yes, solar flares are stupidly powerful compared to the energy levels we're used to, but then you have to remember that the sun is a seething fusion reactor hundreds of times the size of the earth so it's not much of a surprise. Also, why do you mention the 1900's? When speaking on the scale of something that happens every few million years, a century isn't really relevant. I'm not addressing 2 and 3.
Quasars are generally hypermassive black holes, but gamma rays are still light and quasars don't pump out gamma rays directly. The blue stuff you see shooting out the poles is typically interstellar hydrogen that
narrowly escapes being eaten. It just depends on the trajectory of the object near the black hole.
And in other news, this thread is making a lot of you guys remind me of this...
