The scientist predictions

I'm no scientist, so I will try my best of what Ive learned on this part so far. The sun's gravity is revolving off center, and each planet pulls on it as it rotates.Most of all the giant jupiter, being so large. Any extra pull from to many planets pulling at the same time causes a solar flare.In Dec 2012 our solar system will be in direct line with the black hole at the center of our galaxy(The Milky Way).And this will cause more gravity to our sun. The sun haveing all that pull is going to give off more activity then we've encountered before. Giveing the probability of A flare hitting us is more likly.All so changing our gravitational pull causing earthquakes,volcano's,& tsunamis across the earth.
