Had my first jab about a week ago now...a slight fever that night, but OK in the morning. Next jab around end of June. To me science appears to be wanting to be seen as "doing the right thing" in there general honest approach to these vaccines, and being upfront with the fact that a very small tiny minority 'may" be at risk with more serious complications like this clotting issue. They are of course 100% doing the right thing, but in doing so, have imo created some fear among the general populace now. The authorities in Australia have reacted and now are "suggesting" that under 50's take the Physer vaccine if they are overly concerned. I may walk outside my house this morning and get hit by a bus, although my street is not a bus route! When I got my jab [and as is the custom here] my past medical history is considered, my blood pressure is taken, temperature, and a compulsory 15 minute wait time after the jab, just in case.

Been there, done that. 😉

And the next phase begins: Mars Helicopter Ingenuity runs/spins rotor blades motors for the first time On April 9, 2021 NASA’s Perseverance Mars Rover sent images of Ingenuity Helicopter’s rotor blades spin up within motor test. Ingenuity is ready to make First Fly on Mars on April 11-12. Rotor blades spinned up and are unlocked and helicopter is going to make high-rpm test. So next milestone is to spin up rotor blades full-speed for the first time on Mars (to the planned flight speed of ~2400 RPM) while still on the surface. When Ingenuity is flying, it uses a lot of power-many hundreds of watts. The lithium-ion battery that powers Ingenuity's two main propulsion and six blade pitch control motors needs to handle power surges as Ingenuity flies and fights any winds and gusts it may encounter. The helicopter's voltage needs to be maintained so that motors do not stall or electronic devices get in trouble. Ingenuity comes out of the cold Martian night without much energy in its battery, so it needs to bask in the Sun to warm up and let the solar panel charge up the battery enough to handle the power demands of the day. All this means that Ingenuity cannot fly too early in the morning. Midday and afternoon are far better.

Makes sense, still 5ft 2 Inches is short, short! Found some more info with regards to the second query and the emergency which I was unaware of... https://www.euronews.com/2017/02/16/five-reason-why-yuri-gagarin-is-a-legend-of-space extract: "Gagarin almost died during the mission. Nobody was very sure whether Gagarin would survive his flight, and the story goes that he came close to losing his life during the descent phase. Before landing, Gagarin’s capsule was supposed to easily detach from the main spacecraft. However, some of the cables failed to release as they should. This meant the astronaut’s capsule had an extra unit attached to it during its descent. The capsule whirled uncontrollably and the interior temperature rose, meaning Gagarin nearly lost consciousness and barely managed to eject out of the capsule as planned. He eventually parachute d down safely from an attitude of 7km". end extract quote: So the ejection was planned, although it went ahead with some difficullty due to the failure of the detachment mechanism. extract: 4) "Gagarin was chosen because he was a short son of a potato farmer. Soviet cosmonaut selection criteria were a little different to those used today. Firstly, his size. The capsule in Volstok 1 was very small, and so Gagarin’s 1m57cm height made him a strong candidate. Gagarin was so short that he used a cushion on his seat when he flew his fighter jet in order to see better. Secondly, his background. During selection, Gagarin found himself up against Gherman Tiova, a son of a school teacher known for quoting poetry. It was decided that the average citizen of the Soviet Union would be more likely to relate to, and celebrate someone like Gagarin, who was the son of a potato farmer".

On this date, 60 years ago, Yuri Gagarin became the first man in space aboard Vostok 1. 7 years later, he was killed in a crash of a Mig jet aircraft along with another Soviet air force personal named Vladimir Seryogin in what has been claimed to be mysterious circumstances. After doing some research on him I have come across two rather interestings facts. The first is that he was only 5ft 2in [157cms] tall. https://en.wikipedia.org/wiki/Yuri_Gagarin#Death Presumably I would have thought that this may have been due to the confines of the Vostok space capsule, but I find no record of that. Is my assumption correct, or did he just happened to be a shorty? The second revelation is more interesting and came to my attention with the following article.....https://phys.org/news/2021-04-three-man-soyuz-flight-honouring-gagarin.html My query follows from the following.... That seems to infer that he was supposed to have landed in his capsule, and the parachuting ejection was an emergency scenario. Have I read this correctly? Anyway 60 years since the first man in space, is without doubt a great milestone!

Here's a little upbeat ditty about Emus..... Aussie eighties and nineties Television...didn't actually go to air, The show was actually a kid's show called Cartoon connection......

Among the many incarcerated criminals in society, there are a section of really evil incorrigibles that even fellow criminals despise. How much keeping some of these evil arseholes cost society, over a lifetime? Is it worth it? On the other side of the coin of course, there is always the possibility [even possibly among incorrigibles] that an executed person maybe innocent of that particular crime? I don't have an answer either.

https://phys.org/news/2021-04-giant-radio-pulses-pulsars-hundreds.html Giant radio pulses from pulsars are hundreds of times more energetic than previously believed: A global science collaboration using data from NASA's Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying radio bursts from the pulsar in the Crab Nebula. The finding shows that these bursts, called giant radio pulses, release far more energy than previously suspected. pulsar is a type of rapidly spinning neutron star, the crushed, city-sized core of a star that exploded as a supernova. A young, isolated neutron star can spin dozens of times each second, and its whirling magnetic field powers beams of radio waves, visible light, X-rays, and gamma rays. If these beams sweep past Earth, astronomers observe clock-like pulses of emission and classify the object as a pulsar. "Out of more than 2,800 pulsars cataloged, the Crab pulsar is one of only a few that emit giant radio pulses, which occur sporadically and can be hundreds to thousands of times brighter than the regular pulses," said lead scientist Teruaki Enoto at the RIKEN Cluster for Pioneering Research in Wako, Saitama prefecture, Japan. "After decades of observations, only the Crab has been shown to enhance its giant radio pulses with emission from other parts of the spectrum." more at link............... the paper: https://science.sciencemag.org/content/372/6538/187 Abstract: Giant radio pulses (GRPs) are sporadic bursts emitted by some pulsars that last a few microseconds and are hundreds to thousands of times brighter than regular pulses from these sources. The only GRP-associated emission outside of radio wavelengths is from the Crab Pulsar, where optical emission is enhanced by a few percentage points during GRPs. We observed the Crab Pulsar simultaneously at x-ray and radio wavelengths, finding enhancement of the x-ray emission by 3.8 ± 0.7% (a 5.4σ detection) coinciding with GRPs. This implies that the total emitted energy from GRPs is tens to hundreds of times higher than previously known. We discuss the implications for the pulsar emission mechanism and extragalactic fast radio bursts.

https://phys.org/news/2021-04-comprehensive-emdrive.html In a comprehensive new test, the EmDrive fails to generate any thrust: The EmDrive is a hypothetical rocket that proponents claim can generate thrust with no exhaust. This would violate all known physics. In 2016, a team at NASA's Eagleworks lab claimed to measure thrust from an EmDrive device, the news of which caused quite a stir. The latest attempt to replicate the shocking results has resulted in a simple answer: The Eagleworks measurement was from heating of the engine mount, not any new physics. The EmDrive is a relatively simple device: It's an empty cavity that isn't perfectly symmetrical. According to proponents of the EmDrive, by bouncing electromagnetic radiation within the cavity, the tapering in the cavity results in a net thrust of the engine, despite nothing leaking from the drive. In 2016, a team at NASA's Eagelworks lab reportedly measured a net thrust from their EmDrive experiment, which they claimed was a revolution in our understanding of physics and the future of spaceflight. Physicists were… skeptical. Conservation of momentum dictates that a stationary object cannot move without a net force acting on it, which the Eagleworks experiment claimed to violate. But conservation of momentum has been tested countless times over centuries—in fact, that principle forms the bedrock of almost every single theory of physics. So in essence, almost every time physics is tested, so is the conservation of momentum. The results of the Eagleworks experiment were not very strong. While the team claimed to measure a thrust, it wasn't statistically significant, and appeared to be a result of "cherry-picking"—the authors watching random fluctuations and waiting for the right time to report their results. But in the spirit of scientific replication, a team at the Dresden University of Technology led by Prof. Martin Tajmar rebuilt the Eagleworks experimental setup. And they found squat. more at link.....................

The hypothetical scenario being suggested, imo seems to actually be more akin to a hypothetical White Hole then a BH.

Yes, and obviously, part of the reason for the need of the Dawkin's and Krauss' and the DeGrasse Tyson's of this world. May there good work continue. Not forgetting of course, imo the greatest educator of our time, Carl Sagan.

No argument.

Again, I believe that the acceleration in the expansion rate, and the fact that BH's are not all purpose vacuum cleaners outside of 3 Schwarzchild radius, invalidate your hypothesis.. The best example given was that if our Sun should magically become a BH, we would need to squeeze the current mass into a diameter of around 6kms. If that happened, only matter that came within 3 kms of the EH of the 6km diameter BH, would be lost to this BH...that is 1.5 Schwarzchild radius. SMBH's of around 20 billion solar masses have been detected.

Isn't this really just a matter of our own defining? What I'm getting at is that if in that first instant of time, there was more anti matter then matter, we would have an excess of anti matter in the universe...wouldn't we then be calling that anti matter, matter, and the matter, anti matter?

I'm with and for what you said in your last sentence. Religion/belief in any form of ID/creator is more a buffer against the evidenced backed, non caring, indifferent universe we inhabit, and the facts that when we are dead, we are dead. Some, probably most people see that as an uncomfortable disturbing fact, and need an answer or scenario, that over rides that complete indifference of the universe and the finality of death. People are entitled to fabricate any scenario that can give them that warm inner, fuzzy feeling of comfort. That's their choice. It's when they start railing against science on forums such as this, that will have me personally objecting. The Dawkin's and Krauss' of this world, are in reality explaining the science and scientific methodology, against the continued questioning of science, for those amongst us that prefer evidenced backed reality, rather then fabricated myth.

Why would any science forum do that? You obviously miss the whole meaning of why science forums [most of them] exist. It's to discuss mainstream science obviously under the banner of the scientific methodology. That to many folk, [who lack the knowledge and vision as to how awesome and interesting science is] is geeky and boring. They are of course obviously wrong. What can be more exciting, awesome and invigorating, then discussing and learning about predictions made by GR 100 years ago, that have finally in recent times been verified. The problem [as I see it] is with some who come up with what seems like brilliant ideas and theories [to themselves], without actually knowing the data that already exists on that particular area of science, and then get all uppity and upset when their ideas and hypothesis are shown to fail under scrutiny. Many of those people with those ideas, also have some agenda to push. All new ideas and hypotheticals need to run the gauntlet, just as current accepted scientific theories have previously run the gauntlet. In that way forums such as this can be generally assured of "quality over dubious quantity"...isn't that what science forums such as this should be striving for?

Of course! Proper and full scientific study of the small percentage of UFO's that remain as unexplained, is desirable, and I certainly wish that we had the time and effort to undertake that. Again agreed. Which is why I said previously, "finding any ETL will be a scientifically inspiring, enormous, Earth shattering and life changing [to some] discovery." I would add that I envisage a great eruption within some deeply religious communities. Being aware of the problem is the saving grace. Again, all the best.

Don't know the "Hynek" character, but have heard of the parallel universe thingy and similar often. My thoughts? It's speculative and interesting to consider. I have also heard similar [parallel universe] with regards to ghosts goblins etc. I envisage that in time, we may find life within our solar system, [the Oceans of Europa, or Enceledus] but it will be pretty basic...none the less, finding any ETL will be a scientifically inspiring, enormous, Earth shattering and life changing [to some] discovery. I hope I'm still around for that. Agree. Hope it turned out OK with the cancer scare. Personally I imagine myself as aligning with the Richard Dreyfuss character in "Close Encounters of the Third Kind" when he willingly went with the Alien beings to wherever. I would jump at that chance.

"Arguably" we as a species, have reached a certain level of intelligence. Certainly if we were being visited by any Alien ETL, they would be far higher up the intelligence ladder. Considering that, I am rather convinced that if we were being visted by Aliens, they would recognise our level of intelligence, and would not need to approach us or Earth in such a mysterious manner. I am convinced they would make themselves known...Instead of buzzing and/or landing in some backwood territory, and anal probing some poor individual, they would instead make themselves more known, and make their presence official and land in the lawns of the White House, or if they preferred VB, on the court of the Sydney Opera House, or government house in Canberra. I don't accept that they would just be continually flittering in, then flittering out again, creating turmoil and indecision amongst us poor humans, based on the above reasoning. I don't think they would be agressive or beligerent as they would be scientifically advanced and not really want of anything, as anything found on Earth could be also found throughout the Universe... I certainly don't accept the analogy of comparing Aliens and their advanced technology, to ourselves, to that often reference of us [humans] to say ants on an anthill. Examining this phenomena more, we are fairly certain that there is no other intelligent life anywhere within our solar system, so any Alien visitation would need to have crossed many light years of space to reach us and through many other stellar systems with many other planets. In essence, the two major barriers between intelligent Alien contact and us would be time and distance. In saying that, and in understanding that we do not have any evidence of any life existing off this Earth as yet, I personally believe that we are not alone and that out there species exist in various forms, and at various levels of evolutionary intelligence. But as one of the greatest visionaries of our time said, "Extraordinary claims, require extraordinary evidence" Carl Sagan. Finally I would like to say that the two greatest wishes I have in my life and what's left of it before I kick the bucket, is that evidence for some life off this Earth is finally found, and that man has finally set foot on Mars and returned safely. I have heard of him, not sure where and when though...perhaps in Hawking's book, BHoT or something else. His credentials are extraordinary and I certainly would not be dismissing anything that he says, out of hand. I would add though that most physicists and cosmologists believe we are not alone.

Isn't the Earth based dynamics at least partly responsible for the evolution of life [and extinction events] on this planet? the plate tectonics, the 23.5 degree tilt, the Oceanic currents, the winds, the tides, the volcanic activity, etc?

https://phys.org/news/2021-04-stardust-pale-blue-dot-carbon.html We are made of stardust, the saying goes, and a pair of studies including University of Michigan research finds that may be more true than we previously thought. The first study, led by U-M researcher Jie (Jackie) Li and published in Science Advances, finds that most of the carbon on Earth was likely delivered from the interstellar medium, the material that exists in space between stars in a galaxy. This likely happened well after the protoplanetary disk, the cloud of dust and gas that circled our young sun and contained the building blocks of the planets, formed and warmed up. Carbon was also likely sequestered into solids within one million years of the sun's birth—which means that carbon, the backbone of life on earth, survived an interstellar journey to our planet. Previously, researchers thought carbon in the Earth came from molecules that were initially present in nebular gas, which then accreted into a rocky planet when the gases were cool enough for the molecules to precipitate. Li and her team, which includes U-M astronomer Edwin Bergin, Geoffrey Blake of the California Institute of Technology, Fred Ciesla of the University of Chicago and Marc Hirschmann of the University of Minnesota, point out in this study that the gas molecules that carry carbon wouldn't be available to build the Earth because once carbon vaporizes, it does not condense back into a solid. more at link: the paper: https://advances.sciencemag.org/content/7/14/eabd3632 Earth’s carbon deficit caused by early loss through irreversible sublimation: Abstract: Carbon is an essential element for life, but its behavior during Earth’s accretion is not well understood. Carbonaceous grains in meteoritic and cometary materials suggest that irreversible sublimation, and not condensation, governs carbon acquisition by terrestrial worlds. Through astronomical observations and modeling, we show that the sublimation front of carbon carriers in the solar nebula, or the soot line, moved inward quickly so that carbon-rich ingredients would be available for accretion at 1 astronomical unit after the first million years. On the other hand, geological constraints firmly establish a severe carbon deficit in Earth, requiring the destruction of inherited carbonaceous organics in the majority of its building blocks. The carbon-poor nature of Earth thus implies carbon loss in its precursor material through sublimation within the first million years. <<<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>>> What an incredible outstanding example of science at its best!

Getting away from the deeeep philosophical analysis of existence, in reality, it [existence] seems to be a simple explanable result of the BB, or the evolution of space and time. None of us or the chair we sit on and the computer keyboard I type on, would exist without that moment, 13.83 billion years ago. Bingo!! Totally aligning with my thinking. The highlighted sentence, I would just say, that something does not need to be physical or to exist to be real.

Yeah, had me also sort of nonplussed.

We call it road rage in Australia, and we have certainly had many experiences when that rage reaches a stage where personal and property damage has resulted. I'm an old bugger and drive fairly defencefully, and have had experiences with other drivers tooting and yelling obscenities at me if I'm going too slow for them, even though I always keep to the left. [remembering that in Australia we drive on the right side of the road, which is the left, while Americans drive on the wrong side which is the right ☺️] All jokes aside though, it is something that should be eliminated.
