What happens to everything that gets pulled into a black hole? Do planets etc. add to the bulk of the collapsed star causing an increase in it's size and the strength of its gravitational pull? I know what creates them, but as far as anything else concerning black holes goes, I have to plead ignorance.

If each plume is 25,000 light years in length then doesn't that mean that this has been going on for a minimum of 25,000 years? I say this because unless gamma radiation can somehow move faster than the speed of light then it has to be constrained by it right?
I'm sure someone will correct me if I'm wrong here, otherwise this isn't really anything to be scared of since it hasn't bothered us for at least 25,000 years.

clearly from the pictures our galaxys blackhole is emmiting something dont you think?
Dude, for all we really know, the black hole could be emitting the Galaxy. No, really.

nothing can escape the gravity of a black hole lol
except hawking radiation
except gamma rays
i wounder how long the list is going to get
This is oversimplified to the point of nonsense.
If an object crosses the radius of Schwarzschild sphere, then indeed nothing will escape. However, violent processes happening just outside can and will result in emission of all sorts of radiation and particles. That's one of the ways we can explain such emissions happening in the Universe, which can't be explained by normal star evolution.
