Black Hole Information Loss Paradox Solution Proposed
Anuborn Satirak writes to tell us that Physicists from Case Western Reserve University claim to have cracked the black hole information loss paradox that has puzzled physicists for the past 40 years. "The physicists are quick to assure astronomers and astrophysicists that what is observed in gravity pulling masses together still holds true, but what is controversial about the new finding is that 'from an external viewer's point it takes an infinite amount of time to form an event horizon and that the clock for the objects falling into the black hole appears to slow down to zero,' said Krauss, director of Case's Center for Education and Research in Cosmology."
Are they saying black holes are perpetually in the creation phase, or they just don't exist at all unless they formed at the beginning of time?
No, that's not correct. Normal GR predicts that (in the frame of someone away from the BH) the person falling into the black hole will take an infinite amount of time to reach the event horizon. In GR infinite time isn't the same thing as never! In the frame of the person falling into the BH (the proper time frame,) the faller crosses the event horizon in finite time and hits the center quite quickly (for non-huge black holes). The confusion and controversy lies in the concept of infinite time. Some take it to mean that black holes can't actually form (and must either be primordial or not exist). But infinite time might be a finite distance away due to weirdness with coordinates. An object falling through an event horizon might pass through infinite future and then travel back in time from the infinite future to the current. In the outside viewers frame, there might be two copies of the in-falling person, one inside and one outside. In this scenario, black holes can exist, and can contain the mass of stuff that falls into the hole...before it falls into the hole! Or it could all be bullshit and artifact of a broken theory of gravity.
To my understanding, the suggestion is that the collapsing matter will never create a true event horizon (a boundary from which nothing can ever escape). However this doesn't prevent the matter from collapsing to an arbitrarily high density and creating an increasingly large escape velocity. Think of a dense chunk of matter (but not infinitely dense). It will warp spacetime around it significantly, and it will bend the direction of light rays significantly. If a ray of light strays too close to the center of this quasi-singularity, it will get caught in a tight orbit. Now, the orbit won't be truly stable, and the light ray will, after some rotations around the gravity well, finally escape.
The denser the quasi-singularity is, the more rays will get trapped (temporarily) in these orbits, and the longer they will stay trapped. At a certain point, when light is being trapped for 10E80 year, the object could very sensibly be called a black hole. For all intents and purposes, infalling light does not escape. In principle, in a very long time the light may escape. Or, according to this new theory, the black hole may evaporate before actually forming (although this, too, will take a long time). But the massive curvature of spacetime will still lead to all the light-trapping and time-dilating effects normally predicted for black holes. This theory is merely suggesting that the containment is not absolute. Eventually, the stuff will escape. (Although for material objects, they will have been crushed and distorted beyond recognition. But at least in principle, the 'information' about them wasn't lost.)
Under the new theory, objects of near-infinite density still form, and still (in any practical sense) trap all incoming matter. However the question comes down to whether the singularity at the center is a true singularity with a true event horizon, or a perpetually-collapsing mass that has not quite yet reached the point of being a true black hole.

Ohh boy... isnt that like saying the world was flat back in the middle ages? Yet some people the world believe the world is round, sounds good on paper, but really since we cant detect that it its probabley just a belief anyway..
That's an interesting viewpoint, but I don't think you understand physics.
QM lies at the physical border of observable physics. At the QM boundary, concepts we take for granted such as electrons and the speed of light have different meaning. Humanity has nothing to do with it. At a small scale, the behavior of matter changes.
Here's an analogy:
Let's say Newtonian (ordinary) physics involves sitting on the side of the road and tracking how fast people are driving in their cars. From this perspective, you can get a pretty good idea where the cars are going. But there's still some randomness to it, if some driver changes their mind.
In this analogy, QM would be like sitting inside each car tracking who is having what conversation, who is on their cellphone, whether their hands are on the gearshift or on their girlfriend's boob, etc. It's a whole other level that you can't see from the side of the road.
If you could be inside each car, then you would know. But you can't. That's QM, the individual decision-making of each driver on the road.
Each driver==each electron. Whether you choose to track electrons with free will or with robotics, it's still too small and random to keep track of all the time.
