Of course. How else do they keep the flames going?

Black holes are weird shiat. You'd think groceries in them would be cheaper, but they're not. The few food places in neighborhoods with lots of EBT have higher milk and bread prices. I know this from being a stout white guy who got lost in south Dallas. I haven't checked the new Walmart super, but I know the prices in highland village (wighter than sour cream) and I expect prices to be higher in the poor location.

Thus are NOT the object they've been claiming they were.

No Schwartzchild.
No permanent containment.
No, its NOT a "black hole"

Do you even know what any of those words mean?

The amount of radiation flowing out from a black hole cannot exceed a certain level known as the Eddington limit or this radiation will blow gas flowing inward away. This limit is based on the black hole's mass.

The Eddington limit is derived for a spherically symmetric situation, which accreting black holes generally are not.

well du, they are doorways to the dark dimension.

No remarks about subby's mom after a headline like that?

If you like this sort of thing the book Gravity's Engine is a good read.

Thank you for keeping my faith in Fark intact.

Didn't we know this already? I thought this was how Stephen Hawking became famous.

Stephen Hawking wistfully stares into the middle distance; wishes either would happen to him.

Came here to suggest this book also. Well-written, for the layperson, and fairly up-to-date cosmologically. Good stuff. Check your local library!

Arkanaut: Didn't we know this already? I thought this was how Stephen Hawking became famous.


No, that's Hawking Radiation, which comes about because a virtual particle is able to escape from a black hole. Usually, this happens because a pair of particles (one particle and its antiparticle) spontaneously form very near the event horizon, from the cosmic vacuum, and instead of annihilating with each other, one crosses the event horizon and the other does not. The particles form because of the gravitational effects of the black hole (the black hole's gravitational energy gives enough of a "boost" to form the particles), but because only one crosses back over into the event horizon, the half of the total energy that went into creating those particles does not go back into the black hole, effectively bleeding it incredibly slowly.

What is being described in the article is the stellar mass black hole's relativistic jets, which basically come about because the accretion disk, which is mostly hot gas that is being accreted onto the black hole, has a huge confluence of multiple magnetic fields from the gas which eventually line up, due to conservation of angular momentum, onto the rotation axis of the disk itself.

Well, after all that info, have you find anything else?.

Just in the off chance you aren't a troll...

This isn't saying things come from inside the black hole.  Anything that falls in is gone forever, as always.  This is talking about parts of the accretion disk (the gas and dust it's working on eating but hasn't fallen in yet) getting shot out by magnetic and kinetic forces before they fall in.  That stuff is moving a lot faster than we originally thought.

FTA: By analyzing the gas flowing into the black hole, they inferred its weight

Is proclaiming the thread "over" when someone restates the painfully obvious reference made in the headline a new Rotsky variation or something?
