So, now we know that Black Holes have no 'wells' (funneling) but, instead, are disk shaped; these are called 'accretion disks'. We also know that there is nothing on the other side of the Black Hole, yet everything goes into it and nothing ever comes out of it. Where, then, is all of this stuff located.... in the event horizon on the edge of the Black Hole? Let's take another step toward that accretion disk area....๐Ÿ˜€
http://www.stronggravity.eu/public-outreach-tmp/accretion-disks/

A question for thought: For what reason(s) does a Black Hole exist at all in the universes?*-) (Science has no answer....)

One small step further: the Quasar....

'....These accretion disks are also known as quasars (quasi-stellar radio sources). Quasars are the oldest known bodies in the universe and (with the exception of gamma ray bursts) the most distant objects we can actually see, as well as being the brightest and most massive, outshining trillions of stars. A quasar is, then, a bright halo of matter surrounding, and being drawn into, a rotating black hole, effectively feeding it with matter. A quasar dims into a normal black hole when there is no matter around it left to eat....'

Let's peek at the last question:

For what reason(s) does a Black Hole exist at all in the universes?
Any thoughts??? ๐Ÿ™‚

Although science has found no definitive answer as to why Black Holes exist, a few possible reasons - based on the physics of the Big Band Theory - have been suggested: One of these is 'Galactic Evolution'.

"....Original supermassive black holes most likely arose prior to and helped in the creation of the galaxies that continue to spin about them. They were essential to galactic evolution (they still are!) and, in the long run, to the creation of our Sun, our planet and our very existence. They are both the universal omega and the cosmic alpha....."

So, Black Holes may, in fact, have been and continue to be essential to Galactic Evolution! Having said that, was a Black Hole also responsible for the origin of the Universe? Was a Black Hole, in fact, "The Big Bang"?

".... this new understanding compels some to indulge in a bit of speculation that's evocative, intriguing and somewhat disquieting. Could it be possible that the Big Bang was simply the consequence of some universal black hole that accreted all the matter of a previous Universe, imploded then exploded resulting in the Cosmos where humankind exists? ...."

Was a Black Hole, in fact, "The Big Bang"?" ..........my belief is that this may be true! Perhaps some day we might find that to be factual.

Could it be possible that the Big Bang was simply the consequence of some "Universal Black Hole" (of unimaginable proportions as compared to a Galactic Black Hole of which we are familiar), that accreted (devoured) all the matter of a previous Universe, imploded then exploded resulting in the Cosmos where humankind exists?

A question comes to mind: Regarding that possible scenario, what exactly went "hyper-universal-supernovae" to cause that Universe to collapse on itself, thereby resulting in the initiation of a Universal Black Hole ( if we follow the hypothesis that the birth of a Galactic Black Hole is due to the supernovae of a star).

And, in perhaps multi-billions of years from now and into the future, what might happen to 'this' Universe that we live in and enjoy.....after the "implosion and explosion resulting in the Cosmos where humankind exists", will this Universe experience a Cosmic 'Crunch'? After the "implosion and explosion resulting in the Cosmos where humankind exists", was there left behind another Universe-size "Universal Black Hole" that will ultimately accrete this current, new, expanding Universe as it possibly enters the 'Big Crunch' phase? (Is that what accretion is...a 'crunch' whether galactic or universal?).

No one knows, and so it's left for everyone - for all of us - to speculate, ponder, dream about, talk about, research, and have fun with as we stand on our tiny, blue dot admiring what all the cosmos continues to offer us....overwhelming and mind staggering possibilities....

How can one not adore these Black Holes that challenge the science of Physics, stagger the imagination of mathematical geniuses, pose more questions yet to be answered, force the mind to think beyond limitations. "A black hole is a place where you can go in but you can never escape; is there a place where you can leave, but you can never go back?โ€

According to a speculative theory called 'Loop Quantum Gravity', physicists think so: They refer to it as "A White Hole".

"....In 1916, the Austrian physicist Ludwig Flamm, while looking over Karl Schwarzschild's solution to Einstein's field equations, which describes a particular form of black hole known as a Schwarzschild black hole, noticed a possible phenomenon which later came to be known as a โ€œwhite holeโ€. A white hole is the theoretical time reversal of a black hole and, while a black hole acts as a vacuum, drawing in any matter that crosses the event horizon, a white hole acts as a source that ejects matter from its event horizon. Some have even speculated that there is a white hole on the "other side" of all black holes, where all the matter the black hole sucks up is blown out in some alternative universe, and even that what we think of as the Big Bang might in fact have been the result of just such a phenomenon....."

Enter another strange character, one which actually may be the connection between the Black Hole and the White Hole: Meet The Wormhole: ๐Ÿ™‚

Jupiter continues to protect Earth from asteroids and comets that may threaten the very existence of life on our small, blue planet; she doesn't want any additions, deletions, or rearrangements of any planets made within the solar system by wandering space rocks and she plans to maintain harmony among the planets for billions of years to come. Period. You see, Jupiter wanted her own Solar System, but was not large enough to become a star; hence, she adopted our Solar System from our sun, Sol. Saturn deserves much credit in assisting Jupiter in drawing in and tossing out planetary bodies and debris they deemed unwanted. Thank you both....! We enjoy it here....
?1452549106

KISSIMMEE, Fla. โ€” Without Jupiter and Saturn orbiting out past Earth, life may not have been able to gain a foothold on our planet, new simulations suggest.

The two gas giants likely helped stabilize the solar system, protecting Earth and the other interior, rocky planets from frequent run-ins with big, fast-moving objects, researchers said.

In other words, giant planets appear to have a giant impact on giant impacts.

"If you don't have giant planets in your system, you have a very, very different planetary system," Tom Barclay, of NASA's Ames Research Center in Moffett Field, California said here Friday (Jan. 8) at the 227th meeting of the American Astronomical Society.

Barclay and his colleagues found that massive impacts โ€” such as the one involving the proto-Earth that's thought to be responsible for the formation of the moon 4.5 billion years ago โ€” would happen more frequently, and for a longer time periods, in solar systems that lack giant outer planets.

Such giant impacts could result in the loss of a planet's atmosphere, potentially making the world uninhabitable, Barclay said.

"If you have giant planets, your last giant impact happens somewhere between 10 and 100 million years [after planet formation], which is pretty fine โ€” it's like what happened on Earth," Barclay said. "If you don't have giant planets, the last giant impact can happen hundreds [of millions] to billions of years in. This really is a risk to habitability."

As a solar system forms, planetary building blocks and debris zoom around in a broad disk before eventually aggregating into planets with stable orbits. Barclay's group started its simulation after Mars-size planet embryos had already formed in the system, and looked at cases with and without giant planets on the outer perimeter.

The researchers found that, with giant planets around, the remaining small solar system bodies were either ejected out of the system more quickly โ€” because of the angular momentum the gas giants add to the system, Barclay said โ€” or became a part of the existing planets sooner.

Without the influence of giant planets, the fragments formed a large, dangerous cloud orbiting close within the system that took much longer to disperse โ€” kind of like a closer-in version of the icy Oort Cloud, a shell of debris that orbits in the outer solar system and occasionally casts comets toward Earth.

From DanielB_STX - "All can be squared." True. However, that's not the 'rule' regarding the numbers. What is the rule?

The rule for 4, 16, 36 is doubling each number.

The rule for 2, 13, 33 is a finite sequence. You start will adding 11 to 2 then adding 10 to 13 then adding 9 to 33 and so on until you get to 1
