As I guess everyone knows, during the Bin Laden raid the Seal's stealth helicopter crashed. Several things were offered as possible reasons: the stealth modifications altered the flight characteristics in unpredictable ways, it was more humid or hot than they expected, and that the high walls...

Hi, I have some brief questions I was hoping to get some help with: 1. Can any aspect of entanglement survive measurement? What I mean is, does the so-called collapse of the wave function in some sense delete any previous entanglements? 2. Does every event (particle interactions) result in...

I was wondering if there's another aspect to the measurement problem in terms of what one defines as the environment. I don't think I totally get decoherence yet, but doesn't it suggest that the environment gets entangled with the system so that the system's superposition gets restricted to...

Lets say some aliens scaled up the two slit experiment to an enormous size. It is so large that shooting 100kg masses of carbon through the slits creates a diffraction pattern. The aliens then decide to replace the carbon with some captive humans and shoot them through the slits to see what...

Yeah, I am just throwing around ideas, and am not arguing that the human NS would be the only thing that could make an observation (although it might be lol). I don't think QM supports a "physical" universe though as you seem to be using the term. When I ponder the NS bringing a superposition...

Yes, this is actually what I thought PAP says. Other aspects of the system would have been restricted by previous observations, but the main point I thought was, as Wheeler said:"no elementary phenomenon is a phenomenon until it is an observed phenomenon." Think of Wheeler's delayed choice...

Would it matter how the accuracy of the detector is reduced? Let's say you reduce the amount of knowledge by just adding a circuit to the detector that adds electrical noise to the results. Would that decrease in knowledge work as well to adjust the diffraction?

I have a question about the situation with the two slit experiment where detectors are placed by the two slits to determine which slit the particle has gone through (and destroy the diffraction pattern). Okay, so what I'm wondering is what happens if the detectors' accuracy is not fixed, but...

I guess I thought PAP would have a more gradual collapse of the wave function of various systems across the universe, thereby doing a more gradual fine tuning. Just for the sake of this discussion let's just make the huge assumption that wave function collapse is somehow linked to animal...

I have been thinking about this some more and I think it also depends on how PAP would work and how you define universe. I was under the impression that Wheeler thought the fine tuning wasn't a sudden collapse of the entire universe's wave function but more of a gradual process that fine tuned...

Interesting discussion. I just finished reading Lanza's Biocentrism. All the good stuff seems to be what Wheeler already thought up with the Participatory Anthropic Principle. Although I have to admit I never quite understood how Wheeler could violently resist the idea that consciousness was...

Lets say you take a ladder and put it on a scale and measure it's weight while balancing it vertical. If you then lean the ladder at varying angles against a wall, would the scale's reading remain unchanged? I take it that it would, but for some reason this seems odd to me. Lets say the...
