  1. Scientists Discover New Organs in the Throat https://www.webmd.com/brain/news/20201021/scientists-discover-new-organs-in-the-throat Oct. 21, 2020 -- Dutch researchers have found what might be a set of previously unknown large salivary glands in the space where the nasal cavity meets the throat, the New York Times reported Monday. If confirmed, these glands could be the first of their kind discovered in about 300 years. Modern anatomy books show only three types of salivary glands, a set near the ears, another below the jaw and a third under the tongue. "Now, we think there is a fourth," researcher Dr. Matthijs Valstar, a surgeon at the Netherlands Cancer Institute, told the Times. Dr. Yvonne Mowery, a radiation oncologist at Duke University in North Carolina, told the paper she "was quite shocked that we are in 2020 and have a new structure identified in the human body." https://www.webmd.com/brain/news/20201021/scientists-discover-new-organs-in-the-throat BetheLightthatradiatesunconditionalLoveForgiveHealandhaveFun:)

  6. When growing up I thought of the Mormon Tabernacle as a sacred building where the Mormon Tabernacle choir sang and the bi-annual conference was held it's right next to the Salt Lake City LDS temple located in Temple Square I'm shocked at this change in history, so is my Mom who is still a mormon I'm surprised because in church there were always quizzes or games about mormon history where this would've come up prizes were usually a bible, book of mormon, or a CTR ring (Chose The Right) with adjustable band I've seen a lot of old pictures of mormon history, a lot, Ha:) So I was shocked to see the sacred Tabernacle now being used in history as a location & direction display for airplanes In the 1930's it says "SALT LAKE AIRPORT" in huge white letters with a white line arrow In the 1940's they repainted it with "SALT LAKE CITY" with a north arrow and a circle Look at all those flat top building to write on instead of the tabernacle BetheLightthatradiatesunconditionalLoveForgiveHealandhaveFun:)

No more Sox!!! ‘Paradox-free Time Travel Is Theoretically Possible’ Claims University Study https://www.strangerdimensions.com/2020/10/04/paradox-free-time-travel-is-possible-claims-university/ Rob Schwarz 1 week ago A new study out of the University Of Queensland attempts to explain how paradox-free time travel may be possible. Undergraduate student Germain Tobar, alongside physicist Dr. Fabio Costa, did the math. Their goal was to find a possible solution to the so-called “grandfather paradox” — if someone traveled back in time and murdered his or her grandfather, that would prevent the time travel from having ever taken place, thus the paradox. However, according to their study, they may have found a hypothetical scenario in which you could time travel, and even meet yourself, without causing any kind of paradox or disturbance to the timeline. “Some physicists say [time travel] is possible, but logically it’s hard to accept because that would affect our freedom to make any arbitrary action. It would mean you can time travel, but you cannot do anything that would cause a paradox to occur. However the researchers say their work shows that neither of these conditions have to be the case, and it is possible for events to adjust themselves to be logically consistent with any action that the time traveller makes.” Their idea suggests that, if one variable in the timeline is changed, another variable will simply swoop in to take its place, continuing (or “recalibrating” as Tobar says) the timeline along the exact same path. The universe, in this way, is “self-correcting.” From a science fiction standpoint, this sort of idea isn’t particularly new. But seeing the math laid out and a possible explanation for why this might (hypothetically) be the case in the real world is pretty interesting. Just off the top of my head, the 2002 adaptation of The Time Machine shows this kind of “universal recalibration” at work. The time traveler tries desperately to save his fiance from dying. In the original timeline, she dies after a mugging. In an altered timeline, when the traveler attempts to save her, she’s run over by a carriage. “I could come back a thousand times, see her die a thousand ways,” the traveler says. The variables change to compensate for the existence of the time traveler. At least, that’s a fantastical rendition of a similar idea. “…when multiple local regions communicate with each other in the presence of [closed time-like curves], there is a broad range of communication scenarios which still allow freedom of choice for observers in each region without the development of a logical inconsistency such as a grandfather paradox.” You can read the full paper, titled “Reversible dynamics with closed time-like curves and freedom of choice,” right over here. It’s much more technical than the press release lets on, which elevates it above the usual time travel speculation. Now, dipping into ye olde John Titor file (I can’t help it), what did he have to say about paradoxes? “…the reason there are no paradoxes is because the universe doesn’t care how we react to its handy-work. In a Universe made up of infinite worldliness (super universe), everything is possible and has a 100% probability, therefore…no paradoxes.” The universe doesn’t care. There’s a certain elegance to that. https://www.strangerdimensions.com/2020/10/04/paradox-free-time-travel-is-possible-claims-university/ Reversible dynamics with closed time-like curves and freedom of choice https://iopscience.iop.org/article/10.1088/1361-6382/aba4bc Germain Tobar3,1 and Fabio Costa2 Published 21 September 2020 • © 2020 The Author(s). Published by IOP Publishing Ltd Classical and Quantum Gravity, Volume 37, Number 20 Download Article PDF Abstract The theory of general relativity predicts the existence of closed time-like curves (CTCs), which theoretically would allow an observer to travel back in time and interact with their past self. This raises the question of whether this could create a grandfather paradox, in which the observer interacts in such a way to prevent their own time travel. Previous research has proposed a framework for deterministic, reversible, dynamics compatible with non-trivial time travel, where observers in distinct regions of spacetime can perform arbitrary local operations with no contradiction arising. However, only scenarios with up to three regions have been fully characterised, revealing only one type of process where the observers can verify to both be in the past and future of each other. Here we extend this characterisation to an arbitrary number of regions and find that there exist several inequivalent processes that can only arise due to non-trivial time travel. This supports the view that complex dynamics is possible in the presence of CTCs, compatible with free choice of local operations and free of inconsistencies.

Introduction The dominant paradigm in physics relies on the idea that systems evolve through time according to dynamical laws, with the state at a given time determining the entire history of the system. General relativity challenges this view. The Einstein equations, describing the relationship between spacetime geometry and mass-energy [1], have counterintuitive solutions containing closed time-like curves (CTCs) [2–17]. An event on such a curve would be both in the future and in the past of itself, preventing an ordinary formulation of dynamics according to an 'initial condition' problem. The question then arises whether some more general type of dynamics is possible. Although it is an open question whether CTCs are possible in our Universe [18–22], considering dynamics beyond the ordinary temporal view is relevant to other research areas as well. In a theory that combines quantum physics with general relativity, it is expected that spacetime loses its classical properties [23, 24], possibly leading to indefinite causal structures [25–27]. In a quite different direction, it has been suggested that quantum physics could be reduced to some kind of 'retrocausal' classical dynamics [28–39]. The main problem arising when abandoning ordinary causality is the so called 'grand father paradox' [40]: a time traveller could kill her own grandfather and thus prevent her own birth, leading to a logical inconsistency. A popular approach holds that the grandfather paradox makes CTCs incompatible with classical physics, while appropriate modifications to quantum physics could restore consistency [41–56]. A common feature of the proposals within this approach is that they postulate a radical departure from ordinary physics even in regions of space-time devoid of CTCs, or in scenarios where the time travelling system does not actually interact with anything in the past [57, 58]. A different approach is the so called 'process matrix formalism', which takes as a starting point the local validity of the ordinary laws of physics and asks what type of global processes are compatible with this assumption [59–74]. This framework enforces that all operations that would normally be possible in ordinary spacetime should still be available in local regions. First considered in the quantum context, this approach has been applied to classical physics too, with the remarkable discovery of classical processes that are incompatible with any causal order between events [75–77]. In reference [78], a classical, deterministic version of the formalism was proposed as a possible model for CTCs. In this model, one considers a set of regions that do not contain any, but might be traversed by, CTCs. Agents in the regions receive a classical state from the past boundary, perform an arbitrary deterministic operation on it, and then send the system through the future boundary. Dynamics outside the regions determines the state each agent will observe in the past of the respective region, as a function of the states prepared by other agents. A simple characterisation was found for all processes involving up to three regions; furthermore, it was found that, for three regions, all non causally ordered processes are essentially equivalent. In this work, we extend the characterisation of deterministic processes to an arbitrary number of regions. We provide some simple interpretation of the characterisation: when fixing the state on the future of all but two regions, the remaining two must be causally ordered, with only one directional signalling possible. We show, by explicit examples, that there are inequivalent, non causally ordered quadripartite processes, which cannot be reduced to tripartite ones. Our results show that CTCs are not only compatible with determinism and with the local 'free choice' of operations, but also with a rich and diverse range of scenarios and dynamical processes. 5. Conclusions We have developed a characterisation of deterministic processes in the presence of CTCs for an arbitrary number of localised regions. Our proofs have demonstrated that non-trivial time travel between multiple regions is consistent with the absence of a logical paradox as long as once the outputs of all but two regions are fixed, at most one-way signalling is possible. The most significant result of our work is our discovery of distinct non-trivial quadripartite process functions which are compatible with the presence of CTCs. This demonstrates that when multiple local regions communicate with each other in the presence of CTCs, there is a broad range of communication scenarios which still allow freedom of choice for observers in each region without the development of a logical inconsistency such as a grandfather paradox. The range of distinct communication scenarios which are consistent with the presence of CTCs proves that the way CTCs allow multiple observers in distinct regions to communicate is not overly restricted by a conflict between locality, freedom of choice, and logical consistency. As a result, we have demonstrated that there is a range of scenarios in which multiple observers can communicate without causal order in a classical framework. Our results are derived in an abstract framework, that does not depend on the details of the dynamics or of the space-time geometry. Further studies will be necessary to find genuine physical scenarios realising the acausal processes we have discovered. https://iopscience.iop.org/article/10.1088/1361-6382/aba4bc Shown to me by Tim_J, Thanks:) BetheLightthatradiatesunconditionalLoveForgiveHealandhaveFun:)

  16. I Remember humans can't evolve that quickly I Remember taking my pulse in the middle of my wrist now it's in line with the thumb I think the researchers are scratchin' their noggins on this speed-up the median artery sticking around really get my blood pumping https://news.flinders.edu.au/blog/2020/10/08/forearm-artery-reveals-human-evolution-continues/ "Dr Teghan Lucas from Flinders University says this study into the prevalence of the artery over generations shows that modern humans are evolving at a faster rate than at any point in the past 250 years. “Since the 18th century, anatomists have been studying the prevalence of this artery in adults and our study shows it’s clearly increasing. The prevalence was around 10% in people born in the mid-1880s compared to 30% in those born in the late 20th century, so that’s a significant increase in a fairly short period of time, when it comes to evolution.” https://news.flinders.edu.au/blog/2020/10/08/forearm-artery-reveals-human-evolution-continues/ Forearm artery reveals human evolution continues Humans haven’t developed mutations or superpowers just yet, but a new study shows our species is still evolving in unique ways and changes in natural selection could be the major reason. An investigation by Dr Teghan Lucas at Flinders University and Professor Maciej Henneberg and Dr Jaliya Kumaratilake at the University of Adelaide published in the Journal of Anatomy has shown a significant increase in the prevalence of the median artery in humans since the late 19th century. The Median artery is the main vessel that supplies blood to the human forearm and hand, when first formed in the mother’s womb, but it disappears once two arteries seen in adults develop. The radial and ulnar arteries usually replace the median artery during developmental stages in the womb, so most adults obviously don’t have a median artery, but increasing numbers of cases retain it, so a person can have all three arteries. Sketch of median artery vessel which supplies blood to the human forearm and hand. Credit: Professor Maciej Henneberg This evolutionary trend will continue in those born 80 years from today, with the median artery becoming common in the human forearm. Dr Teghan Lucas from Flinders University says this study into the prevalence of the artery over generations shows that modern humans are evolving at a faster rate than at any point in the past 250 years. “Since the 18th century, anatomists have been studying the prevalence of this artery in adults and our study shows it’s clearly increasing. The prevalence was around 10% in people born in the mid-1880s compared to 30% in those born in the late 20th century, so that’s a significant increase in a fairly short period of time, when it comes to evolution.” “This increase could have resulted from mutations of genes involved in median artery development or health problems in mothers during pregnancy, or both actually. If this trend continues, a majority of people will have median artery of the forearm by 2100.” Dr Teghan Lucas, Professor Maciej Henneberg and Dr Jaliya Kumaratilake investigated the prevalence of artery in each generation by analysing published records and dissecting cadavers from individuals born in 20th century. Senior author Professor Maciej Henneberg who is also a member of the Institute of Evolutionary Medicine at the University of Zurich, Switzerland, says the median artery offers benefits because it increases overall blood supply and can be used as a replacement in surgical procedures in other parts of the human body. “This is micro evolution in modern humans and the median artery is a perfect example of how we’re still evolving because people born more recently have a higher prevalence of this artery when compared to humans from previous generations.” “We’ve collected all the data published in anatomical literature and continued to dissect cadavers donated for studies in Adelaide and we found about one third of Australians have the median artery in their forearm and everyone will have it by the end of the century if this process continues.” Other examples of human anatomy changing over time, include the prevalence of spina bifida occulta (opening of the sacral canal), abnormal connections of two or more bones in feet, increasing absence of wisdom teeth, thyroidea ima artery (branch of the aortic arch) – decreased over time, disappeared completely by the end of the 20th century) and fabella (small bone in the back of the knee joint – increased over time). https://news.flinders.edu.au/blog/2020/10/08/forearm-artery-reveals-human-evolution-continues/ Found on: https://old.reddit.com/r/Retconned/comments/j9tyft/its_always_funny_when_science_discovers_new_stuff/ BetheLightthatradiatesunconditionalLoveForgiveHealandhaveFun:)
  17. I Remember 90% total body water in the human body I need a drink......... of H2O "Ugly, ugly giant bags of mostly water." -Lifeforce/form "An accurate description of humans, sir. You are over 90% water surrounded by a flexible container." - Data, Star Trek: The Next Generation By weight, the average human adult male is approximately 60-63% water, and the average adult female is approximately 52-55% water. The figure for water fraction by weight in this sample found to be 58 ±8% water for males and 48 ±6% for females. The body water constitutes as much as 75% of the body weight of a newborn infant, whereas some obese people are as little as 45% water by weight. This is due to how fat tissue does not retain water as well as lean tissue. -https://en.wikipedia.org The amount of water in the human body ranges from 45-75%. The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age. Body composition varies according to gender and fitness level because fatty tissue contains less water than lean tissue. The average adult male is about 60% water. The average adult woman is about 55% water because women naturally have more fatty tissue than men. Overweight men and women have less water, as a percent than their leaner counterparts. https://www.thoughtco.com/how-much-of-your-body-is-water-609406 BetheLightthatradiatesunconditionalLoveForgiveHealandhaveFun:)
