Einstein's general theory of relativity predicts the existence of black holes, formed when giant stars collapse. But that same theory predicts that their centers are singularities, which are points of infinite density. Since we know that infinite densities cannot actually happen in the universe, we take this as a sign that Einstein's theory is incomplete. But after nearly a century of searching for extensions, we have not yet confirmed a better theory of gravity.
But we do have candidates, including string theory. In string theory all the particles of the universe are actually microscopic vibrating loops of string. In order to support the wide variety of particles and forces that we observe in the universe, these strings can't just vibrate in our three spatial dimensions. Instead, there have to be extra spatial dimensions that are curled up on themselves into manifolds so small that they escape everyday notice and experimentation.
That exotic structure in spacetime gave a team of researchers the tools they needed to identify a new class of object, something that they call a topological soliton. In their analysis they found that these topological solitons are stable defects in space-time itself. They require no matter or other forces to exist – they are as natural to the fabric of space-time as cracks in ice.
The researchers studied these solitons by examining the behavior of light that would pass near them. Because they are objects of extreme space-time, they bend space and time around them, which affects the path of light. To a distant observer, these solitons would appear exactly as we predict black holes to appear.

Thanks again for the link!

I doubt that they are defects. They serve a purpose. At the very least so galaxies can form.
bkmk
Black holes are defects?
In before the “That’s Racist” memes!
In my opinion, you can’t have a stable soliton in a scalar field without an opposed manifold such as a spinning vector field. And then you also have to assume the earth is flat.
^^^^^^^^What He Said^^^^^^^^
they’re trying to create a new dilemma that isn’t a dilemma. like you said...what is....is.
Just have Craig Alanson speak his AI “Skippy” to discern all the whys and wherefores of black holes.
Singularities... The new hip word in science.
So, now what they can’t understand is termed “defects in space-time”...even their theories point to a God who lives outside space-time....
AND, there “might” be MORMONS in them too!
All of this astrophysical stuff is a little over my head…but it certainly is fascinating.
I just like getting my scope out under the stars, which I don’t do nearly enough.
In fact, the theoretical framework of Superstring Theory posits that the Universe exists in ten different dimensions.
To much for me
Figures that black holes would use that OS.
lol!
Should have gotten the Universal extended warranty. Good for the life of the Universe or your next Universe free.
