Hey Cancer, quit trying to destroy the universe!

NASA just saw something come out of a black hole for the first time ever

 

 

You don’t have to know a whole lot about science to know that black holes typically suck things in, not spew things out. But NASA just spotted something mighty strange at the supermassive black hole Markarian 335.

 

Two of NASA’s space telescopes, including the Nuclear Spectroscopic Telescope Array (NuSTAR), miraculously observed a black hole’s corona “launched” away from the supermassive black hole. Then a massive pulse of X-ray energy spewed out. So, what exactly happened? That’s what scientists are trying to figure out now.

 

I know you're up to something, so stop it!

Never trusted you astrologers.

I'm sorry, did another universe just knock our universe up? 

 

Bastard should have used a condom!

I am just about certain that this illustration, like just about all of them you will find, give an important and drastically wrong impression.

 

There are lots of astrophysical phenomena which are powered by an accretion feeding onto a central massive object; in this case, a black hole. Accretion disk phenomena are difficult to treat, but the above picture gives the impression that the disk is thin compared to the diameter of the central massive object.

 

At the point where the matter is coming down onto the central thing, that may or may not be true. But further out, it is certain NOT the right picture.

 

The accretion disk is a big fat slab of gas, with the gas moving in orbit around the center thing, and grinding against its neighbor gas, which means the faster it goes the hotter it is (and since it moves faster the closer it is to the center, the hotter it is in the middle), and most (?) of the gas gradually makes its way into shrinking orbits and eventually joins the thing in the middle. A fraction of the gas in the periphery of the disk, though, actually moves outward.

 

This slab is fat. Many many times larger than the central object. In the immediate vicinity of the center object, the disk is pinched thinner. This naturally makes it hotter, as the disk material is grinding against more and more of its neighbors, at higher and higher speeds. And Hot equals Bright, in terms of giving off light.

 

Black holes, kind of by definition, are the most compact things in the Universe. So that fat slab of a disk has to pinch down by a very large factor in the center for the material to feed onto the black hole. And, that only happens in space a few times the black hole's size.

 

The traffic problem is ferocious, and most of the time, some stuff has the spectacular crash with something else that's also trying to cut in line, and pieces go flying. And the only way they can go and keep flying is if they go straight out the pole axis (both "up" and "down" out of it). (Lots of pieces don't go that way; those just rejoin the general spiral-in flow once they've bounced around off of everyone else in the vicinity.) The rest just makes for a nastier hotter traffic snarl in the center, as every car in the Los Angeles Basin tries to swirl down the open manhole in the middle of the intersection of Broadway and 1st Street in the middle of L.A. itself.

 

THE BLACK HOLE IS TINY COMPARED TO THE THICKNESS OF THE DISK. All the pretty pictures of this skimpy disk like an old vinyl LP around the midline of a bowling ball is VERY WRONG.

 

The black hole is a single fleck of black pepper in the middle of a big round fountain a foot deep with pancake batter. If you aren't looking direct down the throat of one of the polar axes, you have NO HOPE AT ALL of having a sightline to the black hole. All you see is either the edge of the disk (if you are kind of in the plane of the disk), or a MOFO INSANELY HOT BRIGHT ZIT right in the middle of the disk, maybe sitting in a dimple but it's hard to see that for sure. And if there has been a cosmic crunchola collision very recently, you may also see the insanely hot blast fragments of the incinerated guts of the sumbeech who tried cutting into line feeding the on-ramp, and those blast fragments have been reduced to fully ionized ten-million-degree plasma and are being expelled at very healthy fraction of lightspeed.

 

But this image of the Big Looming All-Consuming Black Orb looming over the paper-thin sheet of stuff feeding into it ... No. WrongwrongwrongwrongwrongwrongwrongwrongwrongwrongwrongWRONG!

Grumble.
