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

Quote:
Our universe may exist inside a black hole. This may sound strange, but it could actually be the best explanation of how the universe began, and what we observe today. It's a theory that has been explored over the past few decades by a small group of physicists including myself.
Is this TOE? Does it really link quantum-sized world with the Cosmos?

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?

I read this last week when it came out. Pretty interesting but I don't think it's really a new idea.

Isaac Asimov's The Collapsing Universe (1977, and probably quite out of date by now) ends with such a speculation.

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?

It probably loops around in an infinite regression such that no universe is not inside another one. Still looking for the First Cause though.

Thanks Fred. That's a good possibility.

But I don't remember reading this book and quick Google does not show it based on any of his columns.

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.

Some religions have their God breathing life into the Universe. Your approach seems to just as valid.

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).

Quote:
It also appears as a remedy to several major problems of current theory of gravity and cosmology. Physicists still need to combine the Einstein-Cartan-Sciama-Kibble theory fully with quantum mechanics into a quantum theory of gravity.
Ah, so it hasn’t apparently remedied that major problem of the “current theory of gravity and cosmology”. Much like the cart and the horse it seems they are putting the black hole before the universe (well inside another universe with a black hole before that inside another universe with a black hole…) and thinking they might be winning the race before even jumping that first big hurdle (combine the Einstein-Cartan-Sciama-Kibble theory fully with quantum mechanics into a quantum theory of gravity). Heck them zany Physicists need something to do anyway so why not just come up with ‘black holes all the way down’ and let the rest of them zany Physicists figure out how it fundamentally works.

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.

Then Spock will get to meet Evil Spock With A Beard and go to Quark's for a few Pan-Galactic Gargle Blasters. Rowdy Starship Troopers start a brawl and are calmed down by Jame Retief in a diplomatic fashion. John Carter and his trusty Thoat, Freddy, are asking if Thuvia is still tending bar during Friday Happy Week.

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

Well, like Playboy, don't just look at the pictures and you just might find some science (probably more in High Times than Playboy though).

And what if, it stopped expanding and collapsed and.........

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?

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.

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 event horizon of a black hole does expand as the black hole consumes mass and becomes more massive. But the contents of the hole, the mass, is squinched down to a point.

They're hard-pulling bastards, but I very seriously doubt they're universes.
