APOD: GRO J1655 40: Evidence for a Black... (2010 Sep 05)

You mean to tell me that there is an actual Really Big GIANT bar magnet in pulsars?

Yes, and most amazing, it is naturally red at one end and white at the other, and has a giant "N" and "S" engraved on it.
Researchers are still working on extensions to General Relativity to explain these phenomena.

Chris - you wouldn't happen to have some sort of visual or infared picture of that "bar" would you?
I'm feeling a tug on my pants legs.

Are they well ironed pants?

[Beyond]

it's black Holes all the way down.

In the book Small Gods, the question "what does the turtle stand on?" is asked, and gets the reply "It's a turtle, for heaven's sake. It swims. That's what turtles are for."

Gee, thanks owlice. All this time i thought that Turtles were for sunning themselves on rocks and things that stick up out of the water and for singing songs such as, but not limited to - "So Happy Together."

[Beyond]

Are they well ironed pants?

GOOD HEAVENS NO!! I don't want to be sucked up by a pulsar with one of those red and white ended bar magnets and get caught in an engraved S or N.

I saw one of those in my telescope once. I was trying to observe the arrow that points to Pluto.

Is pluto magnetic?

[Beyond]

a black hole can only have three attibutes

Wouldn't the ability to suck up anything that came near it be an attribute?

[bystander]

That's covered by mass, mass implies gravity.

That is a cute little sucker!

AH, so the 'suck' factor is just the result of a really strong gravity caused by all the mass that has been sucked up? Sort of like a self-expanding Vaccuum cleaner??, in that the more it sucks up - the more it sucks up. Would that be considered to be more like a catch-44 than a catch-22?

"Donald and Pluto" September 12, 1936

Click to play embedded YouTube video.

<<From Ryan Kilpatrick at The Disney Film Project : Pluto takes up the majority of the short with a simple premise: he swallows a magnet and ends up having all sorts of things being attracted to his rear end where the magnet is lodged. Pots, pans, knives, Donald’s hammer – they are all chasing Pluto throughout the short. [What] amazes me about Pluto, is that the animators always seem to keep in mind that he is a dog. The human reaction to the magnet antics would be much different than a dog. As a dog, Pluto spends half of his time trying to figure out what is going on, then trying to move on when he’s satisfied that it’s “over.” This is exactly what a dog would do, so it makes perfect sense.>>

Hey - what a good demonstration of the speed of c. In this case c representing the maximum speed of a cartoon dog in a cellulose medium when knives were being attracted to him.

<<English photographer John Carbutt founded the Keystone Dry Plate Works in 1879 with the intention of producing gelatin dry plates. The Celluloid Manufacturing Company was contracted for this work by means of thinly slicing layers out of celluloid blocks and then removing the slice marks with heated pressure plates. After this, the celluloid strips were coated with a photosensitive gelatin emulsion. It is not certain exactly how long it took for Carbutt to standardize his process, but it occurred no later than 1888. A 15-inch-wide (380 mm) sheet of Carbutt's film was used by William Dickson for the early Edison motion picture experiments on a cylinder drum Kinetograph. However, the celluloid film base produced by this means was still considered too stiff for the needs of motion picture photography. By 1889, more flexible celluloids for photographic film were developed, and both Hannibal Goodwin and the Eastman Kodak Company obtained patents for a film product (Ansco, which purchased Goodwin's patent when he died, was eventually successful in an infringement suit against Kodak). This ability to produce photographic images on a flexible material (as opposed to a glass or metal plate) was a crucial step toward the advent of motion pictures.>>

The shape of a black hole's event horizon? http://www.bautforum.com/archive/index.php/t-80286.html

Question: Why do artists always seem to depict a black hole as being below the plane of the incoming material? Is it a misunderstanding of the gravity well?

I don't think it's "always". But in those cases where they do, your hypothesis is probably as good as any.

In this APOD I'm more concerned about the lampshade around the central object. Cosmic censorship?

It may not be that unreasonable to assume the thickness of the accretion disk is larger than the diameter of the black hole.

Black holes do not suck! Or at least, do not "suck" any more (or any differently) than the same amount of mass in any other form would do.

I think that if you happened to get caught in the gravity well of a black hole, you would most likely say it sucks as it begins to deform you on the way to being totally gravitized or whatever it is called when something enters into the black hole. I can't speak from personal experience, so it is much of a guess. But i figure that the word "sucks" would probably fit the situation pretty good.

This is an Electrolux vacuum cleaner, a Swedish brand (or it used to be, I don't know if it is any more):



In the 1950s the Electrolux people tried to come up with a great advertisement that would make American customers interested in buying this Swedish vacuum cleaner. In Swedish "vacuum cleaner" is "dammsugare", literally "dust-sucker", that is, it is something that sucks in dust. So the advertisement the Swedes came up with for the American market was:

NOTHING SUCKS LIKE ELECTROLUX!

So beware, black holes, you little suckers! You've got nothing on an Electrolux vacuum cleaner!

Ann

[Beyond]

Ann, I've got a long canister model, but with a different hose then it came with. They really SUCK!!

[Beyond]

Neufer's Wall e Vacuum cleaner clip video pretty much define's the word "suck" under most conditions.

[Ann]

Wall E's vacuum cleaner didn't suck, it spat out!

But I'll bet there's an Electrolux vacuum cleaner at the bottom of today's APOD black hole!

(And hey... now I understand what a "white hole" is. It is a black hole that spits out the dust it has sucked up, like Wall-E's vacuum cleaner. You only have to wonder why they call it a "white" hole? Did Wall-E look white in that video when he was covered in all that dust?)

Ann

[Beyond]

Wall E's vacuum cleaner didn't suck, it spat out.

EGGZAKLY The situation "sucked" because of what happened, at least to whomever had to clean up the mess and to Wall e who went away in a mess. HAHAHAHA. Funny video. Wall e must be related to Johnny 5, he's such a good actor.

[Beyond]

Could it be a black hole inside a black hole?

Could that possibly be a baby black hole?? if it is, I'd bet that it would be a cute little sucker

Baby dressed in black hole.

Here is an example of a "Black Hole" evolving into a "White Hole." It takes in much material and creates much mass that repels all but the parental Black Holes that created it. The parental Black holes share the task of dealing with the energy input and the mass that is produced as the little "Wonder" grows out of the younger I want it black hole stage, to the more mature adult White Hole stage that puts out useful energies.
