$this->bbcode_second_pass_quote('FairMaiden', 'a')nyone know where fusion is at with regards to implementation?
About as far as Ulam and Teller got.

$this->bbcode_second_pass_quote('EnergyUnlimited', 'B')lack holes are at the moment theoretical objects only and in Nature they may not even exist.
Current astronomical observations are lending some support to hypothesis, that everything what we are considering a BH is in fact MECO (magnetospheric ethernally collapsing object), entity devoid of singularity.
Existance of such objects imply non existance of BH and vice versa.
There is a good chance that Nature is a bit more boring than S. Hawking believes.
The only rigorous solution of Einsteins equations yielding BH is so called Schwartzchild solution.
There is one funny snag in it. It is solution yielding black hole of mass equalling zero, eg it is a mathematical construct yielding entity not capable to exist in physical world.
There are other solutions allowing existence of non zero mass BH, but they are not rigorous (incomplete) and open to challenge.
I suspect more and more, that BH are only product of human imagination and frantic attempts to employ General Relativity to resolve issues ruled by Quantum Mechanics in fact.

OK so what do You, Energyunlimited, think happens to a mass where gravity exceeds the speed of light?
The orriginal classic defenition of a singularity was a point mass that collapsed to such a great density that the gravity field emitted by itself has an acceleration greater than the speed of light, hence any light entering or emitted from the singularity is bent into orbit or reabsorbed below the Schwartzchild radius.
$this->bbcode_second_pass_quote('Alfred Tennyson', 'W')e are not now that strength which in old days
Moved earth and heaven, that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not to yield.

That is wrong question.
What, if it is impossible for gravity to collapse an object tight enough to form event horizon in the first place?
I bet you are aware of so called virtual particles.
In sufficiently dense environment ones with positive energy are "forced into reality" and leaving contracting matter ball as radiation, while negative energy counterpart work towards decreasing of mass of collapsing body...so event horizon actually never forms.
Under this scenario nothing can be squizzed fast enough to form event horizon, before it cease to exist.
Such objects are known as magnetospheric eternally collapsing objects (as they would display magnetic fields) and their existance would imply nonexistance of BH.
Detailed astronomical observations would distinguish between MECO and BH.
Here you have example of such observation, which is supporting for existance of MECO, not BH:

That is definition of BH/event horizon, but not definition of singularity.
If you found yourself in BH with ring singularity (rotating Kerr type BH, in practice any BH, if it exist at all), you would observe singularity emitting light in fact, but light would not leave the hole and would be falling back on singularity).
You would also fail to leave that hole, even if you tried...
Should the hole rotate fast enough, event horizons would "merge" and disappear and you would be observing glowing singularity from the distance.
That would be naked singularity, the one which is not locked in the hole.
You would also observe the environment, where our laws of physics (including concept of causality) are no longer working.

The pp/CNO-based fusion would probable be somewhat complicated, but there are other ways.
