Physicists have insisted for a long time that black holes are impenetrable ciphers. Whatever goes in is lost, impossible to study or meaningfully understand. Some small amount of matter and energy might escape a black hole in the form of "Hawking radiation," but anything still inside the black hole is functionally disappeared from the physical universe.
The idea is a basic premise of modern physics: If something falls into a black hole, it can't be contacted, it's future can't be predicted. No observer could possibly survive traveling into the dark space, not even long enough to glance around and notice a few things before being annihilated.
Now, a team of mathematicians and physicists scattered across Portugal, Canada, the Netherlands and the United States is trying to poke a hole in the hypothesis. It's just a pinprick, but it's already sparked a rush of interest and research from their colleagues.
In a paper published Jan. 17 in the journal Physical Review Letters, the team of researchers showed that in certain extreme situations, black holes could exist that would allow theoretical observers to pass through their outer borders without being instantly destroyed. Plow your shielded spaceship into the event horizon of one of these singularities (the infinitely tiny spots into which all black holes disappear all of their matter and energy), and you might live just long enough to see what's going on inside. It's a crack in the black hole cipher, albeit a tiny one. [What Would Happen if You Fell Into a Black Hole?]
To understand why this is such a big deal to physicists, you have to understand how they think about the universe.
The notion that black holes must be walled off, that their interiors are necessarily impossible to observe, is called the cosmic censorship hypothesis...

MH370 will return.
Big deal. The Pentagon’s budget process accomplishes the same thing, and you can sign up for a tour.
If Congress would pass a Black Hole Neutrality law all would be fixed!

Hare Hooey, as I recall.

Some weeks ago I was watching one of those intermittent science shows about black holes. In fact a whole sequence of episodes about black holes. In one they expressed the notion that the conditions of some massive black holes may be such that they can cause at their cores big bangs which then develop as universes.
This as part of explaining the idea that our own universe is in fact just such a thing, that we exist within a black hole that is itself part of some larger reality.
This notion was hardly novel to me, at least on a personal level, because years ago I noticed the possibility in Einstein’s equations that if time ever became “null” or gravity “infinite” then that point in space-time would suddenly achieve a very low state of energy and as a consequence there would be no reason for all the energy that HAD been there to stick around.
At the time I was pondering just for funsies extreme vacuum and how it might lead to a universe with macroscalar structure like our own (each cell centered around a point where there had been a “Bigish Bang”) and things like dark matter weren’t really on my radar screen.
Still, the idea that a universe could exist in a black hole is not much weirder.
But here’s the thing, in the very next show in the series aired they were discussing the mystery of super massive black holes. Black holes that were simply too large to be explained by any science we know.
Humorously, at least to me, they never even contemplated the universe in a black hole possibility for why.
Consider: we don’t see black holes. We only see their effects. If a black hole is super-massive what we are seeing is not an indication of its MASS but of its SIZE, its surface area.
They apparently assume a large surface area translates into a commensurately large mass.
But now consider what would happen within a black hole that had experienced a Big Bang? Would it erupt within the universe it existed in or would it fluff up, appear larger from without, as some time and dimensionality unfolded within it?
As for the unfolding (subordinate or micro) universe within it, it seems likely that an observer in that universe should be able to eventually perceive the effects of the black hole they existed in, all around them, as mass, gravity and energy ... IOW maybe something like “dark matter” and “dark energy”.
It seemed, at least at the time, that by not noticing this possibility for these giant black holes they were leaving the low hanging fruit on the tree.
And possibly totally imaginary.
Only a very prosperous society can afford to employ such people.
A more appropriate name for them would be “rabbit holes”.
Involves everyone clapping in unison, perhaps.
If they truly believe, that is.
“:it becomes possible for some unknown or unrecognized or as yet undiscovered aspect of reality can come into being and can be recognized by the rest of us.”
I don’t know about it being ‘fooey’. Liberals came up with LGBTQ(an undiscovered aspect of reality) and it is now recognized by the rest of us.
But...but...Can Black holes become transgender?
Huh?
As I recall, he thought we create our own reality as we go along. If enough people believed something, they could bring it into being. Remembering how many people believed in alchemy, I decided more was cracked than the cosmic egg.
Good point. And it didn’t take all that many people to do it.
Now, if they’d just shut up about it.
“And possibly totally imaginary. “
Not that.
I always thought the Wall of Death was the Microsoft blue screen.
AKA "Faith"
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
Yup. I think God allows even pagans to reveal the complexity and overwhelming greatness of His creation to the rest of us. They will have no excuses.
LOL reminds me of the scene in Live Free or Die Hard when the geek explains to McClane that if the chief of the security team of the FBI knew everything the geek knew his fuzzy little head would explode.
