This new zero thermal expansion (ZTE) material made of scandium, aluminum, tungsten and oxygen did not change in volume at temperatures ranging from 4 to 1400 Kelvin (-269 to 1126 °C, -452 to 2059 °F). That's a wider range of temperatures, say scientists from the University of New South Wales (UNSW), than any other material demonstrated to date, and it could make orthorhombic Sc1.5Al0.5W3O12 (catchy name, eh?) a very handy tool for anyone engineering something that needs to work in extremely varied thermal environments. more at link........................ the paper: https://pubs.acs.org/doi/10.1021/acs.chemmater.1c01007 Sc1.5Al0.5W3O12 Exhibits Zero Thermal Expansion between 4 and 1400 K: Abstract Zero thermal expansion (ZTE) is a rare physical property; however, if accessible, these ZTE or near ZTE materials can be widely applied in electronic devices and aerospace engineering in addition to being of significant fundamental interest. ZTE materials illustrate this property over a certain temperature range. Here, orthorhombic (Pnca space group) Sc1.5Al0.5W3O12 is demonstrated to deliver ZTE over the widest temperature reported to date, from 4 to 1400 K, with a coefficient of thermal expansion of αv = −6(14) × 10–8 K–1. Sc1.5Al0.5W3O12 maybe is one of the most thermally stable materials known based on the temperature range of stability and the consistent thermal expansion coefficients observed along the crystallographic axes and volumetrically. Furthermore, this work demonstrates the atomic perturbations that lead to ZTE and how varying the Sc:Al ratio can alter the coefficient of thermal expansion. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: ANSTO = Australian Nuclear Science and Technology Organisation

OK, I watched the video. And I understand why to any individual experiencing such a apparently highly mystical event, such as Pam experienced, may see that as a NDE and view it as she has. Still, the point that struck me was around the 8 minute mark and the "unexplained" conclusion. Science does not know everything as I'm sure you know. Not knowing too much about any supposed NDE, I googled and came across this excellent article in "Scientific American". Please take the time to read all of it...it discusses NDE's from different well known people........ https://www.scientificamerican.com/article/what-near-death-experiences-reveal-about-the-brain/ an extract from the article: "Modern death requires irreversible loss of brain function. When the brain is starved of blood flow (ischemia) and oxygen (anoxia), the patient faints in a fraction of a minute and his or her electroencephalogram, or EEG, becomes isoelectric—in other words, flat. This implies that large-scale, spatially distributed electrical activity within the cortex, the outermost layer of the brain, has broken down. Like a town that loses power one neighborhood at a time, local regions of the brain go offline one after another. The mind, whose substrate is whichever neurons remain capable of generating electrical activity, does what it always does: it tells a story shaped by the person’s experience, memory and cultural expectations. Given these power outages, this experience may produce the rather strange and idiosyncratic stories that make up the corpus of NDE reports. To the person undergoing it, the NDE is as real as anything the mind produces during normal waking. When the entire brain has shut down because of complete power loss, the mind is extinguished, along with consciousness. If and when oxygen and blood flow are restored, the brain boots up, and the narrative flow of experience resumes".

The bombing of Tokyo? All war is basically immoral.

BH's or more correctly, "gravitationally completely collapsed Objects" simply curve/warp spacetime, such that at a parameter called the Event Horizon, the escape velocity equals "c" The Sun/Stars are simply nuclear fusion furnaces that create photons/light.

Thanks for that informative rundown, particularly the highlighted part. In even more recent times, I remember at school [a Catholic school] how with reference to the Vietnam war, the now discredited "domino theory" was shoved down our throats. That of course was shown to be wrong, with the western leaders lead by Einsenhower mistaking their thought processes re the spread of communism, with the real facts of Ho Chi Minh wanting independence for Vietnam and as a united nation.

Nor mine when as a teenage I fell of a second story balcony, or the time I was bowled arse over head by a motor vehicle.... Seriously probably the nearest "death like" experience I have realy had was when under general anaesthetic for a procedure...It was like a slice out of my life...no memory, no recall, no feeling, just blank. I imagine death like that. We are a product of evolution to a stage where we are able to reason, think logically [some of us] have feelings, love, hate, etc

The first militarisitc question in my mind is concerned with more recent times...Like the many times asked question, was the US morally and/or tactically correct in dropping Little Boy and Fat man? Considering what I do know, such as Pearl Harbour, the fanatical "hari kari" approach of Japan in preference to capture or defeat, and consequently the numbers of Allied forces that may have been lost, if invading Japan had of eventuated, the already achieved situation of the Allies having driven Japan back to their homeland and already near actual defeat, tells me sadly, that they really had no choice. In saying that, I have been to Japan twice and find the Japanese as probably the most polite, helpful and considerate people I have seen.

While it only has less then 5% of the total rotational angular momentum of the Solar System. http://www.zipcon.net/~swhite/docs/astronomy/Angular_Momentum.html Plus of course the hottest Planet isn't the one closest to the Sun.

One [religion] was invented/created to explain the natural wonders around him/her, before we had the accumulating scientific knowledge to explain it by thinking logically. The scientific methodology is thinking logically and may change as our knowledge through further observational and experimental data is extended. It is a result of our so called intelligence, and the general desire in how we evolved to our current stage of thinking.

Bullshit.

Point taken.

https://phys.org/news/2021-06-subatomic-particle-antiparticle.html Subatomic particle seen changing to antiparticle and back: Physicists have proved that a subatomic particle can switch into its antiparticle alter-ego and back again, in a new discovery revealed today. The extraordinarily precise measurement was made by UK researchers using the Large Hadron Collider beauty (LHCb) experiment at CERN. It has provided the first evidence that charm mesons can change into their antiparticle and back again. Mixing phenomenon For more than 10 years, scientists have known that charm mesons, subatomic particles that contain a quark and an antiquark, can travel as a mixture of their particle and antiparticle states. It is a phenomenon called mixing. However, this new result shows for the first time that they can oscillate between the two states. more at link............. extract: "Using data collected during the second run of the Large Hadron Collider (LHC), researchers from the University of Oxford measured a difference in mass between the two particles. There was a difference of 0.00000000000000000000000000000000000001 grams—or in scientific notation 1×10-38g. A measurement of this precision and certainty is only possible when the phenomenon is observed many times." the paper: https://arxiv.org/pdf/2106.03744.pdf Observation of the mass difference between neutral charm-meson eigenstates: LHCb collaboration† Abstract: A measurement of mixing and CP violation in neutral charm mesons is performed using data reconstructed in proton–proton collisions collected by the LHCb experiment from 2016 to 2018, corresponding to an integrated luminosity of 5.4 fb−1 . A total of 30.6 million D0 → K0 S π +π − decays are analyzed using a method optimized for the measurement of the mass difference between neutral charm-meson eigenstates. Allowing for CP violation in mixing and in the interference between mixing and decay, the mass and decay-width differences are measured to be xCP = [3.97 ± 0.46 (stat) ± 0.29 (syst)] × 10−3 and yCP = [4.59 ± 1.20 (stat) ± 0.85 (syst)] × 10−3 , respectively. The CP-violating parameters are measured as ∆x = [−0.27 ± 0.18 (stat) ± 0.01 (syst)] × 10−3 and ∆y = [0.20 ± 0.36 (stat) ± 0.13 (syst)] × 10−3 . This is the first observation of a nonzero mass difference in the D0 meson system, with a significance exceeding seven standard deviations. The data are consistent with CP symmetry, and improve existing constraints on the associated parameters.

https://phys.org/news/2021-06-source-gw190814-event-black-hole-strange.html JUNE 8, 2021 Could the source of the GW190814 event be a black hole-strange quark star system? On the 14th of August 2019, the LIGO-Virgo collaboration detected a gravitational wave signal believed to be associated with the merging of a binary stellar system composed of a black hole with a mass of 23 times the mass of the sun (M⊙) and a compact object with a mass of about 2.6 M⊙. The nature of GW190814ʼs secondary star is enigmatic, since, according to the current astronomical observations, it could be the heaviest neutron star or the lightest black hole ever observed. Researchers at University of Pisa, University of Ferrara and the National Institute for Nuclear Physics (INFN) in Italy have recently carried out a study exploring the possibility that the source of the GW190814 event detected by LIGO-Virgo is a black hole-strange quark star system. Their paper, published in Physical Review Letters, is based on an astrophysical model that they developed several years ago. more at link........... the paper: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.126.162702 Was GW190814 a Black Hole–Strange Quark Star System? Abstract: We investigate the possibility that the low mass companion of the black hole in the source of GW190814 was a strange quark star. This possibility is viable within the so-called two-families scenario in which neutron stars and strange quark stars coexist. Strange quark stars can reach the mass range indicated by GW190814, M∼(2.5–2.67)  M⊙ due to a large value of the adiabatic index, without the need for a velocity of sound close to the causal limit. Neutron stars (actually hyperonic stars in the two-families scenario) can instead fulfill the presently available astrophysical and nuclear physics constraints which require a softer equation of state. In this scheme it is possible to satisfy both the request of very large stellar masses and of small radii while using totally realistic and physically motivated equations of state. Moreover it is possible to get a radius for a 1.4  M⊙ star of the order or less than 11 km, which is impossible if only one family of compact stars exists.

My remark [along with the wink] was made due to the gradual thinning ranks of our annual [plus birthdays] old school boy reunions. The 11 has thinned to 9 with two deaths, the 9 has thinned to three of us left in good health, with one confined home with dementia, two others in nursing homes, one with broken hip, two with quadruple heart by pass surgery, and one with ALS [Lou Gehrig's/Stephen Hawking's disease] Out of the three left, one has "controlled" diabetes leaving two of us in good heath. We all have put in $100 each with last one standing to collect. 😅 I'm favourite to collect. 😉 Precisely, all jokes aside. The ancients mistook the purposeless and awesome nature of Earth and the universe around them, as being unexplainable and divine in nature. They saw deities in the Sun, the Moon, mountains, rivers etc. Much of that awesomeness is now explained by natural means we all take for granted. Sure, we still have much to learn, but through the scientific discipline, we can and are doing that. The overwhelming evidence for such cosmic "purposelessness" can be disheartening for some.

Join the club. Granted and correct. But irrespective, our solar system, galaxy and universe all have a use by date. While we may move beyond our system, in time, the same situation will always present itself. Yep correct and understood. We wont actually have any terrestrial planets left in our system, to settle...perhaps Titan, Saturn's largest moon?

We already see various stages of stellar evolution as we are exploring the heavens. Why would our system be any different? According to the observational evidence yes. Future great scientists more then likley could see human civilisation flourish on another planet to extend our species...Mars for example... Even if any future advanced civilisation achieves any of what you suggest, our solar system, our galaxy and our universe, all have a "use by date" Nothing gloomy about it, just plain ordinary fact/s based on current scientific knowledge and observational data. We all, everything has a "use by date".

Survival; and learning, achieving, loving, and having fun in that endeavour. I plan on living forever...so far I'm doing OK!😉

The following details how and why Trump was being egregious in the extreme in ignoring the science, and how Biden followed the science. https://phys.org/news/2021-06-biden-administration-key-environmental.html JUNE 5, 2021 Biden administration will restore key environmental protections: The administration of President Joe Biden on Friday announced it would restore protections under the Endangered Species Act, a law credited with saving iconic animals like the gray wolf and bald eagle, which were loosened by his predecessor Donald Trump. ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Hope that helps.

Yes, as happens often on science forums...game time for the kiddies!

Hmmm, do you understand why others may laugh/snigger and dismiss that rant as totally nonsensical?

On the present subject of the pandemic, Trump said something along the lines of injecting disinfectant, and during many of his meetings/addresses/gatherings etc, mask wearing and social distancing was not evident. He also ignored the advice of science in many other areas, particularly with regard to pollution and climate change. Biden does not seem to be egregious at all, despite your inferences, and is following the science, and the recomendations of science as our knowledge of this virus improves. Of course, I speak as an outsider [not from the USA] but it is worth noting that even my own right of center government, generally ignored/sniggered at/or outright laughed at some of the antics of Trump when he was in power, a reaction that also seemed to be from the rest of the world in general. His extreme reaction/s and his inactions many times over, when he was in power, seemed to reflect on him as an extreme politically reactionary red neck ratbag to put it mildly. My only criticism of Biden is his age. He appears to be doing pretty well and has rightly taken action in undoing some of the anti science nonsense that Trump egregiously initiated.

Sure it is!! If you are able to support it with credible evidence.

Keep following the science.

I don't see that as an all out mathematical revolt, and certainly will not stop the LHC and its continued application to the science of sub atomic particles and the early universe.
