It Really is "Turtles all the Way Down".
Sometime in the my dim distant past, before the days of the Internet when paper still ruled, I remember reading an article in ISTR a science fiction magazine that claimed the the Universe was a Black Hole because it was of the right density to be one -- the size of a black hole been dependent on its mass and all that.
Then today I read: Every black hole contains a new universe By Nikodem Poplawski ++ Published May 17, 2012 ++ Inside Science News Service

People were playing with this back in the 90s. On the basis that your source is fox news rather than any popular science book written in the last 20 years I'm kinda worried.

Maybe this will help with the legitimacy of the source?
http://phys.org/news/2012-05-black-h...-solution.html ![]() I read this last week when it came out. Pretty interesting but I don't think it's really a new idea. |

Recent observational evidence suggesting the universe is in fact accelerating in its expansion might just put the black hole theory back in the game

So, if the universe is in a black hole, what do we call the thing that has all the black holes with universes in them?

What would this mean for cosmic drift and the universe flying apart into a cold death? Would there be any indication of scale or size in terms we can relate to?
As a kid I used to be fascinated with the idea that there were infinitely regressing and progressing universes both inside and outside of each other, a never ending babushka/matryoshka doll in both directions. |

A fractal universe... just the thought made my stomach churn from that old existential feeling.

Intriguing article. I know nowhere near enough to determine whether it's credible though...

Black Holes all the way down (who would have guessed).
Wait, so every black hole in our universe has another universe inside it and our universe is inside a black hole of some other universe that is inside a black hole of some other universe that is inside a black hole of some other universe that is inside a black hole of some other universe that is inside a black hole of some other universe that is inside a…..
So its black holes all the way down now instead of turtles (heck at least the turtles were kind of a cute image).

Nah, not an infinite regression. Just three. The black holes inside the black holes inside the black holes don't have anything in them.

Why three? Just because that’s how many licks it takes to get to the center of a Tootsie Pop? (you know the owl was the wisest). Without some special pleading those last terminal layers (nothing inside the black hole below and no black hole around the universe above) are going to need some real fundamental differences in the quantum gravity that explains their formation. Oops there's that big first hurdle again.

It is absolutely special pleading, in that I made it up entirely.

This thread already existed earlier today and last evening or I have somehow skipped through a sister black hole on my way back from the bat'leth tournament. Which one of you is my wife again?

Pretty sure I've seen Sol shoot down this idea with a very simple argument based on observations which contradict the possibility.

How was that falsified?
Which prediction? Which observation? |

I don't know dude but that was like so excrementally phantasmagorically deep. You should like do that thing where you know you like write stuff down and then people like read it. Dude that would be so assume. You could bifurcate the disestablishment and recoflabulate it to a more incohesive, sorry, dicocohesive embellishment. You know what I'm saying!! Ok, who's got the liter?

Didn't Hawkings' 1993 book "Black Holes and The Baby Universes" deal with this as well? http://en.wikipedia.org/wiki/Black_H...d_Other_Essays |

Baby universes don't need black holes to hide in. They can be spawned by random quantum fluctuations, breaking off from the underlying Void into their own private spacetimes.
The black hole speculation requires that a universe must already exist, to make the black holes the baby ones are born in. This is madness. How did the first one come about? If you imagine an infinite regression, then how did the entire infinite regression come about? What kind of hole was IT born in? Therein lies madness, and then religion. |

How about science by science. Just because this article is the first you've heard of it doesn't mean the same is true for everyone else. This is absolutely real science. It may well be wrong, but that's a very different matter.
Indeed. I doubt we'll ever get an answer that will settle that part. Either you need to get something from nothing, or it's infinite turtles. Even if we manage to come up with what seems to be a definitive answer, it's just not going to satisfy most people since neither of those options really seem to make sense from a human-scale perspective. |

We don't need to get something from nothing if 'nothing' is a bogus concept to begin with. All that's really required is a fundamental, timeless Void (the closest possible 'something' to the contradictory nothingness), and you've got your bottom turtle. Then all you need is quantum mechanics, which apparently thrives in a Void. Both Void and mechanics were noticed decades ago, and have been successfully toyed with since.

Black holes are finite in size, they have event horizons and at least from the outside would appear to have a middle. Also, don't they collapse inward, not expand outward?
[The author of this post admits having not yet read the articles and to only skimming the other thread posts. ]
