The original press release said that the jet (from the poles) is now pointing directly toward us. That makes it a "blazar". https://spaceref.com/science-and-exploration/a-galaxy-changes-its-classification-as-a-relativistic-jet-changes-direction/

This article would probably put a lot of minds at ease. Headlines today made it seem like we're totally screwed.

I read the og article and had an existential crisis for the first part of my day and this put my mind at ease

Wouldn't all black holes face everything? Isn't it a sphere?

A black hole's event horizon is spherical, yes. But some black holes rotate, and thus have a top and bottom. The article is saying that the top or bottom is facing us.

So is it shooting stuff at us or sucking us in and how far away is it half a galaxy away or just a few systems over
__Raptor__ t1_jdxsdu9 wrote
Its shooting stuff at us. Or, rather, has been for 657 million years and its just taken that long for the light to reach us.

Black holes don't "suck things in" anymore than anything else in the universe does.

That would make the black hole 2 dimensional. I really doubt they are 2d

Actually, the current model treats them as such! A spinning black hole is treated like a ring with 0 radius, and a non-spinning one is treated as a point.
The laws of physics break down within a black hole. Time and space literally reverse.

I think our understanding is so limited. Maybe a few lifetimes from now we will be sending probes into them to see them better.

You cant. Nothing escapes the gravity of a black hole. Not light, not energy, not even time.
Postnificent t1_je35ubz wrote
You do realize that is still a theory? Problem is we don’t have actual local black holes to throw things into to test the theory. We have recently learned some black holes spit stars out so some things escape sometimes and we won’t fully understand them for a long time.
__Raptor__ t1_je3cukh wrote
where the heck did you learn that???

Hells bells, that one was on CNN among other places. The fact is we think we know all these things about space and all we know is what we observe vs what a couple guys guessed far before space travel was possible. That’s not facts, facts are observable. The theory was nothing escapes, the fact is this is how stars are made…

That is not how stars are made. A black hole is a star corpse.

Now you aren’t ignoring me, you are ignoring astronomers, astrophysicists and scientists. What we think and “know” are two different things. You keep presenting theory as fact. Science much?

Beyond the possibility of Hawking radiation, all current understanding has it that nothing can cross back out from a black hole's event horizon.
And /u/__Raptor__ is correct. Black holes certainly don't "spit stars out." In fact, large star life cycles end with black holes. If CNN said otherwise, they're quite wrong, perhaps misunderstanding orbital ejection of objects outside the event horizon - a phenomenon common to all multi-body orbiting systems, not just black holes.

As I told him you can go do your own research. Space is dynamic in the fact that our understanding of it changes almost daily at this point. We are constantly learning new things. Just because you haven’t learned the new information doesn’t mean it doesn’t exist. Imagine the concept that we don’t know everything. Because we don’t. We think lots of things, doesn’t mean they are correct. I’ve been tired of this conversation. It’s obvious that I am not on the same wavelength as the rest of this thread. I learned a lot about this particular Reddit and the experience was the opposite of positive. Congratulations to everyone who participated, you definitely helped me formulate an opinion about this place.

When reading such ignorant and sensationalized press reports, consider when they're reporting on subjects about which one is not familiar, and wonder then on the inaccuracy there.

Headline: Earth faces a Black hole, World is relieved from mass destructive.

black holes with jets that point toward Earth are called blazers. They’re not that uncommon so I’m not sure what the news is here? “Object in universe rotates” is not really news?
