Guys, you really should read a lot more about astronomy.
We have nothing to fear of the black hole in the center of our galaxy.
It's not like we are sucked into it in a straight line.
Our solar system is rotating around it, like the earth is rotating our sun.
The closer you get to an extremely heavy body, the faster you'll rotate around it.
Luckily, there is nothing to force us closer to it. Or further from it.
During the creation of our galaxy, the last couple of billion years, matter (like stars and planets) has been formed in certain orbits, at certain speeds, which makes them not being slung into outer space, neither being sucked into the center. It's been in balance ever since.
The distance totally depends on mass. Mass doesn't easily change on cosmic scale. Imagine, if earth were to be 40 times as heavy all of a sudden, e.g. if Mucky would drink all Stella available, or dorito would gain all the muscles needed to beat cujo at arm wrestling, yes, then earth would distance itself from the sun. But only slowly. Simple mathematics.
I'ts like slinging a 200 pound heavy hammer around instead of a 5 pound hammer.
Our star system is more organized than you think Canner.
It seeks balance constantly.
True, our galaxy has been gobbling up other small galaxies. But a collision on this scale takes millions of years to 'flatten out'. The age of humanity means nothing in these terms. A solar system like ours could even live on happily during such an event, like nothing had ever happened. If our sun would be the size of a tennis ball, in your hand, the closest next star would be on the surface Jupiter. Chance of a direct hit is close to zero.
Better yet, our galaxy is on a collision course with another galaxy.
When I reach king pro status on Quakelive, in a couple of million years, our galaxy is going to collide with the Andromeda Galaxy. Which is really large. Larger than our Milky Way. But, even then, damage is going to be minimal, due to the enormous mutual distances between stars.
They'll just swing around the two black holes, seeking balance. Only to change orbits of planets on a minimum scale.
However an impact I wouldn't like te be around is when our center black hole is going to merge with the Andromeda black hole. That's gonna be major fireworks. But that won't happen in the next 100 billion years...
These 'Local Fluffs' you're talking about are the remains of supernovae in our star system, creating interstellar winds our system is 'flying' through.
Our sun's heliosphere is capable of withstanding most impacts of cosmic radiation, luckily.
Besides the 'Local Fluff risk' and the 'Center black hole risk' you guys mention, there is at least one really serious risk we face:

If I were to choose, I'd pick World War III above this one anytime.
Pics are really cool tho. Very few can understand the beauty of these photographs, because it lies beyond their imagination.
Pity for them. But if you can actually see it, they show the most beautiful view man in our time will ever see.
