  1. The reputation system is a weird blend as a gauge of how much a poster contributes. Every member gets one vote on each post, even staff. You talk down about science quite a bit, so perhaps you've acquired some haters (or misread your audience?). You seem to enjoy an aspect of competition that embraces denigration of a perceived "opponent", which is very common in people who like to "debate" what they think they know. All of this tends to sit poorly with people who just want to discuss science and learn. We have to hope you don't start really trying. It's all about expanding my

  2. Quantum entanglement is neither to do with non-locality, nor with action at a distance; it has to do with non-separability of states, and statistical correlation of measurement outcomes. This difference is crucially important. The outcome of each measurement is subject to the usual rules of quantum mechanics, so the entanglement is not apparent to either one of the observers until they compare measurement outcomes - which is of course only possible at or below the speed of light. So no exchange of information at superluminal speeds is possible; and of course it can’t be, since entanglement fea

  3. Do you know of any laws that are completely resistant to varying interpretations? Seriously asking because I'd say there are none, but you're welcome to try and change my mind.

  4. The are actually saying very strongly what youre pointing out in their own paper right after the 2 proofs on page 11: "4. Examples The above characterisation of process functions allows us to consider specific examples that cannot occur in an ordinary, causally ordered spacetime" is my layman understanding of this correct?: We can very much time travel without the risks of getting into the grandfather paradox with just a small exception - we can’t do it in our universe?

  5. That is speculative. And not at all consistent with the accepted definition of a Closed Timelike Curve. https://en.wikipedia.org/wiki/Closed_timelike_curve

  6. Black holes are very small in relation to their mass. The whole Milky Way is somewhere between 100-200 thousand light years across. Yet its Schwarzschild radius is about 0.31 light years only. On the contrary, the accelerated expansion is only noticeable beyond the range of billions of light years. So black holes would never overcome expansion. The mass would have to be ridiculously big. You can do the comparison yourself. G=6.674×10−11N⋅m2/kg2 c=3×108 ms-1 1 light year = 3×108 ms-1 × 365×24×3600 s M = (1 billion light years)× c2 /2×G Somewhere a

  7. Scientists have alerted to this fact. Suddenly this gives people wise like us. But yes I know. Let's say the universe at its beginning was no bigger than a pinhead.

  8. It's not clear how that is an example of this If you say "And if We desire, We may return them to that state again", I'm going to laugh at you. Not because the statement is religious, but because it is absurd. We simply do not have that ability or anything like it, no matter hat we may "desire". There are statements in various religious works that forecast an end to the universe. With a bit of care, you may be able to "interpret" them so that they coincide with either a Universe ripped apart by dark energy or a "heat death" as the universe expands and cools.

  9. I don't understand the question. To apply scientific principles to develop a solution to a problem that can then be patented surely requires being creative. What does "simply being creative" mean?

  10. Your question is ambiguous. I am wondering whether you're talking about instructions of TCP protocol or instruction like command-line or what else? If you want to learn PID you can try: Dump all active processes to a text file before running something, dump it again after running something, compare the differences between text files.. and you will know which processes were created by "something". You can make a script. Dump, compare, display differences, wait 0.1-1s, repeat.

  11. Human, and that’s only a crude summary, since there’s detail that “interpretation” doesn’t necessarily cover. Philosophy and religion are also interpretations of the universe, but these are not science.

  12. Nonsense, and nonsense clouded by a needlessly verbose and loquacious post. The number of Justices on the SCOTUS is both arbitrary and unconstrained. There could a thousand Justices if that’s what the congress decided. Even if statutes actually bounded the allowed number (which they don’t), it is the Congress who authors those same statutes anyway. Summarized, it can be changed and your point is moot. To be frank, your post also comes across as historically ignorant. In 1789, the SCOTUS had 6 Justices. Then in 1807 there were 7 Justices. Then in 1837 the number bumped up to 9, and

  13. Thank you for the references. Yes, this (mild) scepticism has been in the air for quite some time. Back in year 2000 you simply could not say you had problems with Copenhagen's interpretation without being classed as a heretic. It was dogma, no doubt due to its astonishing calculational power. Adding to it was Von Neumann's impressive authority on the matter, that went almost unchallenged for decades. It is my posture that the standing uneasiness can be addressed through a concept sketched by John Bell's (one of the first Copenhagen's sceptics) notion of beables. If you wholeheartedl

  15. Yes it's ambiguous for others who Demystifies Entanglement and Quantum Nonlocality or find A Closer Connection Between Entanglement and Nonlocality But I understood that both have nothing to do. It is true that the correlation was subject to debate namely the transfer comes at the start or after. For the rest it is a nice explanation. Thank you

  16. Exactly my usual points about this question. Correlations are there since the very start of the state preparation. So nothing non-local is implied. This is the problem: Suppose elementary particles (say, electrons) are coloured balls. Balls can be found to be in any colour state as referred to a basis R, G, B, and you have devices to measure this "colour." You set both balls to be in an overall state that is white (colourless). So there is perfect anticorrelation; when one of them is found to be at R (total redness) the other one is found to be at GB (total anti-redness). For

  17. Due to the effects of gravity. Remember that in General Relativity, all forms of energy-momentum are sources of gravity, not just mass; so whether the universe contracts, expands, or stagnates just depends on the average energy-density, even if there is no conventional form of mass). Note also that in this scenario there would be no singularity; contraction just turns into expansion below a certain minimum scale.

  18. More to the point of OP's topic title "Constitutional laws" and OP's questions. In order for any form of human government to be "constitutional", it must be founded upon a "constitution" that establishes the parameters that such a form of government must be founded within by constitutional boundaries established within its constitution. If such a constitutional form of government be a Constitutional Democracy or a Constitutional Republic, is an experimental a priori (relating to or denoting reasoning or knowledge which proceeds from theoretical deduction rather than from observation

  19. I haven’t bothered with the details because the basis of the argument is invalid. Once you posit that the moon is made of cheese, I don’t need to delve into the subsequent analysis. It would be a waste of time. Not at all. You can analyze linear actuators with newtonian physics in an inertial frame. It’s ludicrous to suggest otherwise.

  20. Laymen are like any student. They are arguably more passionate than most undergrads, in being so self directed. I have a question for you. How many of the individuals you speak to online, have personally self identified themselves to you, as either a layman or an expert in a given field? How are you judging and determining who is who? Really? Without an exception? That doesn't sound like Laymen at all. It sounds like atheists, with zero appreciation for the literary arts and the power of writing. I've met plenty of researchers from Atheistic, Theistic to Agnostic, who had t

  22. We are almost certainly limited this way, but that’s why we build instruments. They can be sensitive to signals that humans aren’t Science is not the search for truth. Science is our attempt to discern how nature behaves, because behavior is what we are able to test.

  23. Those were actually sincere suggestions. If you were a little less worried about your own ego and being right, then maybe you'd see them as such. Sounds to me like you just don't know how to respond to my posts so you are making problems where there are none. If we were in a classroom debate, you wouldn't have the luxury of ignoring what I said if you wanted to get a good grade. It's only presumptuous if I'm wrong. You've not given me amy indication that is the case. At the risk of sounding like a math teacher, show me your working please.

  24. Yes this confuses many people and is not the only situation in Science where sign conventions differ. Here we have the situation that the original Laws of Thermodynamics were written by folks who worked with steam engines. They put coal or wood into the machine and took mechanical work out. To derive the First Law break the process down into two stages, so there is an intermediate stage. First add the heat put in from the coal, then subtract the work performed by the machine. The machine must have had some internal energy to start with add to this the heat energy

  25. Look MSC, the Mods created this site. Why do you think they did that? Was it to further the progress of Science. Or was it or another reason. Such as expanding their own ego's?
