  1. Einstein's theory certainly is correct within its known bounds of applicability, but the non existent problem you present is actually explained by good old Newtonian mechanics. The Sun and planets formed from a rotating accretion disk 5 billion years ago, the angular momentum of that disk, saw it flattened so enabling the Sun/planets to form in nearly all the same plane. Much the same reason applies to why the Earth is an oblate spheroid.
  2. And of course before I forget, and to avoid any need to address this again, jailing criminals is not just about incarceration, it also is for punishment and deterrence. To repeat as I see you have raised it again.....Society in general is demanding more thought into the "softly softly" approach, as I exampled earlier, and it is not all based on one sensational media story (not sure how one can sensationalise the violence and repeated rape of a little girl by a monster already out on parole?) It is based on many cases, and near everyday and that's just in my own little corner of the world.
  3. No actually I'm arguing against someone who at times is talking in riddles and ignoring hard facts. I'll end this little escapade now, as you finally have agreed to what I am saying in as many words. Far better then any unrealsitic, unworkable system with no jails, which you were pushing. And really whatever you mean by my revenge beyond incarceration is beyond me. I have already said I disagree with the death penalty for obvious reasons, and I certainly have not mentioned anything about whipping, stoning, or other torture in anyway...perhaps some fabricated drama on your part?
  4. You won't be banned for disagreeing with anyone. You are at a science forum, and while certainly this is in the religious section, the scientists here, and others like myself, have every right to question your "absolute claims" specifically when they are not supported by evidence. The bible is simply an obscure book, mostly based on myth, written in an obscure age, by obscure men. If you want yes answers with no questions asked re your claim, then your best bet is to go to a forum where similar unscientific beliefs are the norm...Freewill is imho, simply a product of evolution that enables reasonably advanced Apes to make decisions, reason, chose, and act independantly. Others might argue that in reality we do not have freewill, as that and us, are governed by the laws of physics. Also the quantum world and/or determinism may have some effect on what some may determine as freewill. https://link.springer.com/article/10.1007/s40509-014-0008-4 "Quantum theory and determinism usually do not go together. A natural combination is quantum theory and randomness. ... But I feel that we should not give up the idea that the Universe is governed by a deterministic law. Quantum theory is correct, but determinism is correct too". https://link.springer.com/content/pdf/10.1007/s40509-014-0008-4.pdf Abstract: Historically, appearance of the quantum theory led to a prevailing view that Nature is indeterministic. The arguments for the indeterminism and proposals for indeterministic and deterministic approaches are reviewed. These include collapse theories, Bohmian Mechanics and the many-worlds interpretation. It is argued that ontic interpretations of the quantum wave function provide simpler and clearer physical explanation and that the manyworlds interpretation is the most attractive since it provides a deterministic and local theory for our physical Universe explaining the illusion of randomness and nonlocality in the world we experience. 6 Conclusions: "In this paper, I reviewed the interpretations and the fundamental aspects of quantum mechanics, arguing that, contrary to a popular view, quantum theory can be considered as a deterministic theory describing Nature. The theory has two parts. The first part is physical, mathematical, the one to which I attach the words “ontological” or “ontic” (without attributing a distinction between them). It is a counterpart of the theory of particles and fields in classical physics. This is the part of a theory about what is in the physical Universe. Although I discussed several approaches, I find by far the best option to take the wave function of the Universe, and only it, as the ontology of the theory. Major part of the paper explains why I have this view. I also review numerous recent works on the subject pointing in this direction. The theory of the wave function is a deterministic theory without action at a distance. It is the theory about what is, irrespectively of us. Even quantum observables, like momentum, energy, spin, etc. which are frequently considered to be the starting point of quantum mechanics, are not considered ontological in this approach. Thus, various uncertainty relations between quantum variables do not lead to indeterminism". ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: personally, I havn't got a bloody clue as to where freewill comes from, but am inclined to accept that it is simply a product of evolution.
  5. Thanks for that...I was looking forward to some reasonable critique on the matter, as I was somewhat questionable on the full nature of their claims in my OP. Still, its progress and who knows where to from here......the mind boggles!
  6. https://www.smithsonianmag.com/smart-news/scientists-unveiled-the-worlds-first-living-robots-last-year-now-they-can-now-reproduce-180979150/ Scientists Unveiled the World’s First Living Robots Last Year. Now, They Can Reproduce: By clustering free-floating stem cells together, ‘xenobots’ can assemble baby bots: Early last year, a team of researchers announced the world's first living machines—bundles of stem cells from African clawed frogs (Xenopus laevis) that could be programmed to accomplish certain tasks. The sand grain–sized cells could successfully move microscopic objects, whiz around Petri dishes and even self-heal, Katherine J. Wu reported for Smithsonian last year. "Most people think of robots as made of metals and ceramics but it's not so much what a robot is made from but what it does, which is act on its own on behalf of people," co-author Josh Bongard, a computer scientist at the University of Vermont, tells Katie Hunt for CNN. "In that way it's a robot, but it's also clearly an organism made from genetically unmodified frog cell." Since their original study, the team has been working to harness the power of these tiny robots—named "xenobots" after the clawed frogs' genus Xenopus. In a new development, the team announced that xenobots can now reproduce in a way that is completely different from any plant or animal known to science: by scooping up free-floating cells and assembling them into new clusters, Nicola Davis reports for the Guardian. The team published their findings this week in the journal Proceedings of the National Academy of Sciences. more at link...............
  7. As far as I am aware, a singularity can be defined as where infinite spacetime curvature and densities take place (this version is generally rejected by most scientists) and a singularity defined by where our laws of physics and GR are non applicable. https://www.universetoday.com/84147/singularity/ The Hawking Singularity Theorem added to this by stating that a space-like singularity can occur when matter is forcibly compressed to a point, causing the rules that govern matter to break down. Hawking traced this back in time to the Big Bang, which he claimed was a point of infinite density. However, Hawking later revised this to claim that general relativity breaks down at times prior to the Big Bang, and hence no singularity could be predicted by it. """""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" The highlighted part by me, can I believe also apply to the core of a BH. The predicted singularity obviously applies to singularities as defined by infinite spacetime curvatures and densities.
  8. This is getting boring and again going round in circles....Are you at all listening to me? obviously not with those blinkers. Let me simply repeat...... Obviously the biggest unworkable scenario re your softly softly approach, is the fact that due to the numbers of incorridgibles and criminals re-offending when being given the softly softly approach, many areas of society are instead increasing incarceration terms, and reducing rehabilitive solutions. As I have said a couple of times, this is just making it harder for the young first timers that deserves a chance, with judges and magistrates being less inclined to be lenient. Let me get straight to the point again...I'm all for rehabilitation after punishment, and protection of the victim and society, but some crimes are so animalistic, so violent, so horrific, so utterly evil, that rehabilitation is out of the question. In other words, I would rather err on the side of caution, and chance not giving a criminal a second chance that may well deserve it, to giving some (unknown) incorridgilble bastard a second chance ( as in my "ad naeseum" example) that will go out and commit another horrific deed. ( as per the ad nauseum example) which of course has been shown to be more common than what you are trying to pretend it is not. You are corrected....(other then a night in the clink at the local police station when I was about 20 years old, for being drunk and disorderly) I was just that, ( drunk and disorderly), although the disorderly part was simply me singing loudly around 0300hrs on the way home and waking up the neigbourhood) and accepted my punishment. 😁 Society in general is demanding more thought into the "softly softly" approach, as I exampled earlier, and it is not all based on one sensational media story (not sure how one can sensationalise the violence and repeated rape of a little girl by a monster already out on parole?) It is based on many cases, and near everyday and that's just in my own little corner of the world. Here's another for your collection.......... https://www.mamamia.com.au/murders-by-people-on-bail/ The question of bail is a question of human rights. Every person has the right to the presumption of innocence – or is “innocent until proven guilty” – as stated in The Universal Declaration of Human Rights. It’s about freedom and justice. The entitlement to a fair trial. But people are dying and we have to ask why. When people like 40-year-old mother Teresa Bradford is stabbed to death in her own home while her four children (the youngest is eight) are in the next room, we must wonder how, why, the man who killed her – her husband, 52-year-old David Bradford – was free to do so. Mr Bradford had been in court less than three weeks prior to Tuesday – the day he murdered his estranged wife. He’d been in custody since November for assaulting and choking Ms Bradford. He had knocked her unconscious, gaffa taped her mouth shut, and attempted to strangle her. Despite police opposing bail, he was released after 44 days in detention. Bradford, who was in custody for 44 days, had known mental health issues and a domestic violence support group was aware of the risk he posed to his former partner. https://www.9news.com.au/national/bail-laws-masa-vukotic-sydney-siege-jill-meagher/258febb5-4601-4325-a9c4-8360e3336587 :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Oh heck, here's another..... https://www.mondaq.com/australia/crime/1126996/man-granted-bail-for-proceeds-of-crime-charges-disappears A man who was granted bail for proceeds of crime charges has disappeared after cutting off his ankle monitor. Mostafa Baluch is accused of masterminding a 900kg cocaine shipment into Australia. However, he was granted bail when he agreed to forfeit his $4million property and wear an ankle monitor. Police described him as "dangerous" and urged the public not to approach him. ::::::::::::::::::::::::::::::::::::::::::::::::::
  9. Hasn't this "unphysical" prediction been rejected by scientists? If by unphysical, you mean a singularity of infinite density and curvature. And of course ( my reasoning now) GR tells us nothing about the quantum/Planck region, where this prediction takes place...so in effect it can be reasonably discarded. Which then leaves a physical singularity with a surface of sorts, (in an unknown state of existence) at or below the quantum/Planck level. Of course all predictions inside the EH are essentially unknown. With any Kerr BH, (the most likely real life example) we would have a "ring singularity" If one were to enter the BH at the polar regions and survive spaghettification, one could pass directly central through this ring singularity without any catastrophic effects. The gravitation would be equally acting on all sides.
  10. It does work in most cases as is evidenced in society. The cases where it isn't working are the examples of incorridgible evil criminals...you know, those that sometimes you reluctantly admit to existing. And "your alternative" has been shown to be unworkable. These studies you fall back on, studies of psychiatry and physiology are known as "soft sciences"...while in some respects they are indispensible, they are labeled soft sciences for a reason. Why not use the many real to life, factual examples I have given? Instead of blocking your ears and going nanannanana. Instead, it seems you have found a new word to hang your hat on....sad. 🤕 You see your problem is equating revenge to punishment. But obviously you need that error as the foundation of your philosophy. "First, revenge is personal, an act of private justice taken by individuals for wrongs done to them or to those close to them, usually blood relatives. ... Punishment thus commits itself to impersonality, where the response to an offense is assumed by an authorized third party, typically the state". https://science.jrank.org/pages/10919/Punishment-Vengeance-Punishment.html Judges also obviously are prone to errors, as was shown in my prime example. Thankfully, ( as I'm sure you will agree) that error was not made the second time around. Not forgetting of course that this monster's name was not Robinson Crusoe. Obviously the biggest unworkable scenario re your softly softly approach, is the fact that due to the numbers of incorridgibles and criminals re-offending when being given the softly softly approach, many areas of society are instead increasing incarceration terms, and reducing rehabilitive solutions. As I have said a couple of times, this is just making it harder for the young first time that deserves a chance, with judges and magistrates being less inclined to be lenient.
  11. It was you who labeled the thread a pantomine...(presumably because you could not offer any challenge to real true to life examples that invalidated your "justice philosophy") It is you quoting Jesus....it is you claiming others have resorted to gainsay and ridicule and consequently casting aspersions..... Yet in the next breath you (reluctantly) admit that incorridgible criminals do exist. That therefor constitutes the need for prison and jails. We all agree that rehabilitation should be attempted, but we also need the deterence factor...that's what prisons and punishment is for.
  12. https://phys.org/news/2021-12-astronomers-strangely-massive-black-hole.html Astronomers discover strangely massive black hole in Milky Way satellite galaxy: Astronomers at The University of Texas at Austin's McDonald Observatory have discovered an unusually massive black hole at the heart of one of the Milky Way's dwarf satellite galaxies, called Leo I. Almost as massive as the black hole in our own galaxy, the finding could redefine our understanding of how all galaxies—the building blocks of the universe—evolve. The work is published in a recent issue of The Astrophysical Journal. The team decided to study Leo I because of its peculiarity. Unlike most dwarf galaxies orbiting the Milky Way, Leo I does not contain much dark matter. Researchers measured Leo I's dark matter profile—that is, how the density of dark matter changes from the outer edges of the galaxy all the way into its center. They did this by measuring its gravitational pull on the stars: The faster the stars are moving, the more matter there is enclosed in their orbits. In particular, the team wanted to know whether dark matter density increases toward the galaxy's center. They also wanted to know whether their profile measurement would match previous ones made using older telescope data combined with computer models. more at link.............. the paper: https://iopscience.iop.org/article/10.3847/1538-4357/ac0c79 Dynamical Analysis of the Dark Matter and Central Black Hole Mass in the Dwarf Spheroidal Leo I: Abstract We measure the central kinematics for the dwarf spheroidal galaxy Leo I using integrated-light measurements and previously published data. We find a steady rise in the velocity dispersion from 300'' into the center. The integrated-light kinematics provide a velocity dispersion of 11.76 ± 0.66 km s−1 inside 75''. After applying appropriate corrections to crowding in the central regions, we achieve consistent velocity dispersion values using velocities from individual stars. Crowding corrections need to be applied when targeting individual stars in high-density stellar environments. From integrated light, we measure the surface brightness profile and find a shallow cusp toward the center. Axisymmetric, orbit-based models measure the stellar mass-to-light ratio, black hole mass, and parameters for a dark matter halo. At large radii it is important to consider possible tidal effects from the Milky Way, so we include a variety of assumptions regarding the tidal radius. For every set of assumptions, models require a central black hole consistent with a mass (3.3 ± 2) × 106 M⊙. The no-black-hole case for any of our assumptions is excluded at over 95% significance, with 6.4 < Δχ2 < 14. A black hole of this mass would have significant effects on dwarf galaxy formation and evolution. The dark halo parameters are heavily affected by the assumptions for the tidal radii, with the circular velocity only constrained to be above 30 km s−1. Reasonable assumptions for the tidal radius result in stellar orbits consistent with an isotropic distribution in the velocities. These more realistic models have little need for a dark matter halo.
  13. https://phys.org/news/2021-12-astronomers-binary-star.html Astronomers observe a new type of binary star long predicted to exist: Researchers at the Center for Astrophysics | Harvard & Smithsonian have observed a new type of binary star that has long been theorized to exist. The discovery finally confirms how a rare type of star in the universe forms and evolves. The new class of stars, described in this month's issue of the Monthly Notices of the Royal Astronomical Society, was discovered by postdoctoral fellow Kareem El-Badry using the Shane Telescope at Lick Observatory in California and data from several astronomical surveys. "We have observed the first physical proof of a new population of transitional binary stars," says El-Badry. "This is exciting; it's a missing evolutionary link in binary star formation models that we've been looking for." MORE AT LINK.............. the paper: https://academic.oup.com/mnras/article-abstract/508/3/4106/6368873?redirectedFrom=fulltext Birth of the ELMs: a ZTF survey for evolved cataclysmic variables turning into extremely low-mass white dwarfs: ABSTRACT We present a systematic survey for mass-transferring and recently detached cataclysmic variables (CVs) with evolved secondaries, which are progenitors of extremely low mass white dwarfs (ELM WDs), AM CVn systems, and detached ultracompact binaries. We select targets below the main sequence in the Gaia colour–magnitude diagram with ZTF light curves showing large-amplitude ellipsoidal variability and orbital period Porb < 6 h. This yields 51 candidates brighter than G = 18, of which we have obtained many-epoch spectra for 21. We confirm all 21 to be completely or nearly Roche lobe filling close binaries. Thirteen show evidence of ongoing mass transfer, which has likely just ceased in the other eight. Most of the secondaries are hotter than any previously known CV donors, with temperatures 4700 < Teff/K < 8000. Remarkably, all secondaries with Teff≳7000KTeff≳7000K appear to be detached, while all cooler secondaries are still mass-transferring. This transition likely marks the temperature where magnetic braking becomes inefficient due to loss of the donor’s convective envelope. Most of the proto-WD secondaries have masses near 0.15M⊙0.15M⊙⁠; their companions have masses near 0.8M⊙0.8M⊙⁠. We infer a space density of ∼60kpc−3∼60kpc−3⁠, roughly 80 times lower than that of normal CVs and three times lower than that of ELM WDs. The implied Galactic birth rate, R∼60Myr−1R∼60Myr−1⁠, is half that of AM CVn binaries. Most systems are well-described by MESA models for CVs in which mass transfer begins only as the donor leaves the main sequence. All are predicted to reach minimum periods 5 ≲ Porb min−1 ≲ 30 within a Hubble time, where they will become AM CVn binaries or merge. This sample triples the known evolved CV population and offers broad opportunities for improving understanding of the compact binary population.
  14. That to me says he did not know, or was not sure, of her age. 🙄 You did then of course move the goal posts when a reasonable answer was given re who the victim was. Either way, yes as an adult, he needs to shoulder some responsibility, part of which would include drinking in moderation, although essentially he still is the victim, and the girl a coniving little criminal. Then you went on to argue about who can know all the facts and who has the right to judge. Which was wisely answered by Intoscience along the lines of who elects our officials. Nothing to do with credulity or incredulity for that matter. The cases I present that invalidate your dream (just within my own region) are real examples of crime, rehabilitation attempts, cruelty, violence, victims, and justice, where sometimes locking them up and throwing away the key is the only option. Sadly I don't see that scenario changing anytime soon.I +1 and therein lies the meat of this debate. Colour me also as not strictly aligning with all new age political correctness. IMO, though, in time, it will settle down....the extremes of political correctness will rightly fade into oblivion and the reasonable aspects will become the norm, and much thankfully already has.
