I'm a Computer (Web) Programmer/Analyst based in Anchorage, AK and Minneapolis, MN. I use (among other things) ASP.NET, C# and SQL Server.

I build things. Bicycles, computers, websites, guitars, cars, motorcycles, sound sytems... lots of things.

comment Could the Heisenberg Uncertainty Principle turn out to be false?
The Heisenberg Uncertainty Principle is an unfalsifiable claim? All of (good) science is falsifiable. See the first paragraph: en.wikipedia.org/wiki/Falsifiability

comment Would it be economical to add a counterweight to rocket launches?
How about four steel cables, each holding 100 tons? Some bridge reinforcement cables are rated for more than this.

Further, I do refer to wikipedia. Since you seem to be of the opinion that this has been answered therein, could you provide a wikipedia link that properly addresses this question?

I'm aware the total energy would be the same, but lifting the counterweights could be powered by renewable resources like wind and solar, reduce the amount of fuel carried to start acceleration and thus lowering the weight and thus further reducing fuel (the Tsiolkovsky rocket equation), and could perhaps be economical across multiple launches.

In the case where pair formation happens within the event horizon and the escaping particle 'tunnels' out, then I can perhaps see some energy theft as it leaves the event horizon (though how it does so, I do not understand). However, pair formation could take place outside of the event horizon, in which case how does a particle not in the event horizon leaving take energy away from the black hole?

Okay, so you have a real particle, with mass, leaving. By what mechanism does the virtual particle 'steal' energy or mass from the black hole by falling into it? Does it annihilate a particle without a release of energy? The outgoing particle can't balance its own creation energy, or even if it did how would that affect the black hole whatsoever?

comment Since when were Loop Quantum Gravity (LQG) and Einstein-Cartan (EC) theories experimentally proven?
"Fully compatible with observation" seems to mean, at minimum "no observations currently contradict it". This would, at least on the surface of it, apply to string theory.

But then, if the in-falling particle is/becomes real, wouldn't that just add to the energy of the black hole? Wouldn't it need to have negative energy, or negative mass, to 'rob' from the black hole and balance the conservation of energy? (and lead to the disintegration of the black hole?)

Would this summation be accurate: "In an instance in which one member of pair production is taken out of the negative energy well, the well converts itself into providing mass of the remaining particle"? It seems a bit bizarre to me that it somehow 'chose' which particle to provide mass to, why couldn't it provide mass to the in-falling particle instead?
