This will probably get me in trouble ( with the usual suspects ), but I would add to Joigus' point ... And there are plenty more genetic conditions and 'abnormalities', which we apparently spend millions of dollars researching ways to cure. Why do some 'abnormalities' require concentrated efforts to find cures or treatments, but, just mentioning 'cure/treatment' for others gets you labelled a '****phobe', or worse ? Please explain.

What I make is classified as a WMD by the American Government. Phosphine, liquified at 700 psi, tends to blow-up quite nicely on escape to atmosphere ) I seem to recall the FBI coming up to tour/investigate our facility.

I don't do 'tweets' nor do I care what others 'tweet' about in social media. ( forums is as far as I go ) And my opinion of Joe Rogan is that he should have stuck to announcing MMA fights.

I just noticed a mistake in my post which might confuse some, in Phi's quote. Where it says should say my apologies.

Virtual particles are properties of a quantum field, below the threshold of action that would render them real. The only way to claim virtual particles are a property of space, or space-time, is if you consider space-time a quantum field. GR considers the geometry of space-time a field, but one that is purely classical in nature. There is, currently, no description of space-time, and its associated vacuum energy, as a quantum field. LQG might strive to do that; I'm not sure SString theory does.

What oother view would you expect me to take ? We are discussing humans., are we not ? I've been called worse. 🙂 INow recently called me a fascist.

While I agree with his first post on the matter, once he shifted his focus to Israel, I have to again disagree I don't know why the focus of the thread shifted to Israeli actions ( most of this thread was posted shortly after my eye operation ), but the above seems an irresponsible statement. Russia occupied the Ukraine for over 50 years, under the guise of the USSR, took all of their produce to sell and finance their 5 year modernization plans, and in the process, starved 8 million Ukrainians to death. ( yes, 8 million; more than the Jews that died in the Holocaust ) Three years ago, Russia again invaded the Ukraine, branding them Nazis, and currently has 300000 troops in Ukrainian land which they have seized by force and untold missile attacks. ( and I won't even mention China and its oppression of some of their people, and people of lands they've occupied, like Tibet ) Yet, Mistermack, who has openly defended Russia's actions in the Ukraine on this forum in the past, chooses to call out Israel as the worst offender ? Methinks there is a bit of anti-Semitism at play here. ( it's a good thing I don't give demerits )

I could very well be a descendant of B Mussolini. 😁

I will try to explain to the best of my abilities ( and without giving demerit points ), even though I sometimes find the situation ridiculous myself. Words are defined by context. In reproductive Biology there are only two sexes, because an idealized male of the species is needed to reproduce with the idealized female of the species. However, in modern Fashion, it is difficult to define male clothing and female clothing, as there is a huge amount of overlap These are extreme examples, so before Phi calls them 'flippant, and non-serious', I should explain further. I'm of Southern European discent, and in the summer my skin is darker than a couple of black individuals that I know. Yet, if I 'perm' my hair into tight curls, and 'identify' as black, I cannot use the 'N' word, as that usage is now based on a shared cultural experience. If their group uses the term,it brings them together, if others use it, it offends. And I understand that, and am fine with it. When it comes to the term 'woman', however, that term is still in general usage, and some people feel free to include themselves in the group denoted by that term. And I can sort of understand that also. Some feminists, however, and people like J K Rawling, are wondering why women don't deserve to 'own' their shared cultural experience as they have a much longer history of oppression all over the world. And I can understand that too. The confusing part, for me, is that we choose to avoid offending people who want to identify as 'women' by not letting the group own their shared cultural history, and 'owning' the term, and continuing to be oppressed. Doesn't seem very enlightened to me, and very possibly needs more discussion, not less. But what do I know, I usually get neg reps also when discussing similar subjects, as if discussion is not needed ( or wanted ).

But we need armed militias to prevent the Government from 'fixing' the outcome of the Super Bowl ... It's a Constitutional right.

I didn't notice a question in the OP ... And who the f**k builds looms ? ( are you now in Pennsylvania, Dim 😄 )

That is commendable, and it is the law, here in Canada/ Unfortunately, some areas of the US are still the 'wild west' when it comes to carrying and storing firearms. Here in Canada, most of the legal guns on the street come from break-ins and theft from legal gun collectors and hobbyists. Actually, a lot are stolen in the US, and smuggled into Canada. Most are handguns. No gang member will steal a hunting shotgun; it cannot be concealed. ( and you can't hold them sideways, like you can handguns, for that extra 'wow' facto )

Single place or single time makes no difference to Heisenberg. Singular place means infinitely indeterminate momentum, and singular time means infinitely indeterminate energy. Either way, that electron cannot be confined. Hawking radiation is generated just outside the event horizon, and Heisenberg Uncertainty applies everywhere, as it is a fundamental aspect of nature.

I am not understanding these 'ruptures' of space-time you speak of. And how they arise from conditions more extreme ( ? ) than those that lead to a Black Hole. You cannot curve space-time any more than a Black Hole does. And Black Holes certainly don't cause 'ruptures' in space-time or negative time dilation. ( too much Star Trek or Marvel multiverse madness ? ) I have a simple argument against the existence of central singularities in Black Holes. Consider an electron swallowed by a BH. It crosses the EV and reaches the 'singularity'. At this point its position is exact; it is a point. That means that, according to Heisenberg, its momentum ( and speed ) could be any value up to infinite. That means the electron could escape the BH. Since this same argument can be applied to every other particle swallowed by the BH, every particle could then escape, and there would be no BH And since we have photographic evidence that BHs exist, the above inconsistency means that singular points, in a BH, cannot be possible.

OMG ! It's worse than Vietnam ... I'm starting to have flashbacks of 'typing' Hollerith punch cards, to solve the energy levels of the Helium atom, circa 1978-79.

The direction is uncertain before an interaction and collapse. The spins are always opposite, before or after the collapse. Some observables are always uncertain.

Sometimes the models we build allow for predictions which are non-physical. They are 'weeded out' by inconsistencies that arise ( you should look into some of the absurd properties negative mass would have ), or experimental observations.

Maybe I got it confused with Canada's 36 million. I'm over 65 now; my mind is starting to go. ( or, maybe your immigration system/laws need to change ) At the time that was the definition of 'arms'. Today 'arms' means automatic assault weapons, as well as turbine engined tanks, stealthy fighter jets, aircraft carriers the size of a town, and chemical/biological/ thermonuclear weapons. Do you think that because the American armed forces have them, any rich individual should have access to them also ? ( hate to imagine what that goofball, E Musk, would do with an aircraft carrier )

Com puters are specific to their use. An old Pentium will suffice for Net surfing, as the speed is limited by your internet connection, not computing power. But you might want a Ryzen with 16 cores if you want to edit graphics or videos. Similarly guns have specific purposes. An assault rifle of low caliber has little stopping power and is almost useless for hunting game larger than a rabbit. Its purpose is to incapacitate, as a wounded enemy combatant will tie up two others to care/carry him, while a dead enemy can be left behind. You don't want to have wounded game run off and die somewhere you cannot find it, so assault rifles are bad for hunting. I read statistics that 360 million Americans own 400 million guns, but 3/4 of Americans do not own guns, only 1/4 of them do. At some point, it is simply saying " look, I have more, bigger, guns than you." Nothing more than showing everyone that you have ( are ? ) a bigger dick. And those insecure incels are the ones usually committing the mass killings

Energy and mass are equivalent properties. You cannot have negative mass without negative energy, and the same arguments against their existence apply to both. Only 'exatic' matter is postulated to have negative mass/energy, but it could be just an 'accounting' trick as it is the complement of Hawking Radiation and must be harvested just inside the event horizon of a Black Hole. Good luck with that. The speed a light, c , is reserved for massless particles and nothing having any mass can reach that speed. At one time Tachyons were postulated, which move faster than light and cannot ever slow down to the speed of light, travelling backwards in time. The term Tachyonic has recently gained a new meaning. Particles or quantum fields with imaginary/complex mass are unstable, and said to be tachyonic. see here Tachyon - Wikipedia and here Tachyonic field - Wikipedia

Excellent video, JC. I think you should ... Pay special attention at the end where he explains how neither Republicans or Democrats fixed anything during the years they each controlled all parts of Government. But the blame game works and keeps politicians getting re-elected without ever having to do anything abut it. And the fact that all American politicians are rich enough to have illegal aliens as gardeners, nannies, drivers, etc. ( no sense having to pay Americans real living wages for those 'menial' services )

Sorry. I guess I picked the wrong choice from the auto-correct suggestions.

Going by purely Heisenberg considerations, if at a certain scale translational symmetry ceases to have meaning, can a classical theorem like Noether still say anything about momentum conservation ? If position and momentum are 'fuzzy', or smeared out, translational symmetry and momentum conservation must necessarily be also. Feynman diagrams essentially put a box around an interaction within which all possible series of interaction can happen. The largest series of interactions, with the most nodes are least likely to be realizable as they describe virtual interactions, which are 'off shelf' and don't need to satisfy energy-momentum considerations. I would think that means our current models do not necessarily conserve energy or momentum at small enough scales. The conservation condition is approached, or emerges, when off shelf virtual particle effects become negligible, and you 'zoom back' out of the Feynman box. And it is already exceedingly difficult to keep the few electrons trapped in narrow, shallow potential wells, at current feature size of modern semiconductors in order to define logic levels, but Moore's Law has had a good run, going from a couple of thousand transistors 50 years ago, to over 100 billion in Apple's latest ARM implementation.

Helium ?!?!? Imagine how bad the executioners would feel whrn the condemned person starts talking with a little girl's voice.

very badly posed question. Of course it depends on the properties of the objects in the box. What if they are a lite -weight sponge, and make no noise ? What if they are a compound object, like 'nested' balls, that make multiple sounds on collision ? the hardest part of finding an answer is making sure you ask the right question. And you can call it AI modelling, but it's still a computer, so the old adage still applies; "garbage in, garbage out".
