Black Hole Emits a 1,000-Light-Year-Wide Gas Bubble

PhrostyMcByte writes "12 million light-years away, in the outer spiral of galaxy NGC 7793, a bubble of hot gas approximately 1,000 light-years in diameter can be found shooting out of a black hole — one of the most powerful jets of energy ever seen. (Abstract available at Nature.) The bubble has been growing for approximately 200,000 years, and is expanding at around 1,000,000 kilometers per hour."

Re:How can a black hole emit anything?

I love how people talk about black holes like they know how they work.

It always amazes me that both laymen and scientists as well talk about such things as if we KNOW whats going on.

We don't. We have theories. I assure you, without a bit of doubt, that should we ever get close enough to a black whole to actually uncover its secrets we will be utterly if not completely wrong about our understanding of them.

We don't know how they work, stop pretending we do, all we have is some observations made based on assumptions that other theories are correct, ignoring the fact that these underlying theories and the theories about black holes themselves don't even all actually add up without us throwing in random tweaks for reasons we don't have the slightest understanding of.

We don't know shit about black holes, even if we have seen a couple drive in movies that talked about them in the cosmos.
