A Star Grazed Our Solar System 70,000 Years Ago, Early Humans Likely Saw It (space.com)

schwit1 shares a report from Space.com: Some distant objects in our solar system bear the gravitational imprint of a small star's close flyby 70,000 years ago, when modern humans were already walking the Earth, a new study suggests. In 2015, a team of researchers announced that a red dwarf called Scholzs star apparently grazed the solar system 70,000 years ago, coming closer than 1 light-year to the sun. For perspective, the suns nearest stellar neighbor these days, Proxima Centauri, lies about 4.2 light-years away. The astronomers came to this conclusion by measuring the motion and velocity of Scholzs star -- which zooms through space with a smaller companion, a brown dwarf or "failed star" -- and extrapolating backward in time. Scholz's star passed by the solar system at a time when early humans and Neanderthals shared the Earth. The star likely appeared as a faint reddish light to anyone looking up at the time, researchers with the new study said. The study has been published in the journal Monthly Notices of the Royal Astronomical Society: Letters.

      It's more complicated than that. The extent of the Oort cloud is determined by where things that are nearly stationary WRT the gravitational dominants would fall towards the Sun rather than towards some other source. So a star approaching will alter the shape (and membership) of the cloud, as it's moving a new strong gravitational field into the area. Also it's not a sphere, being shallower in the direction of the Alpha Centuari system, because that's got it's own area of dominance, and it extends further in directions that are far from any near star.

      That said, there's no good measurement of how densely populated the Oort cloud is. Or even whether there are any fairly large planets in it. It wouldn't be impossible that there's something the size of Neptune floating around out there, and we haven't seen it, because it's *DARK* out there. The best chance of seeing it would probably be in the infra-red. But my real guess is that there are a lot of things smaller than Pluto, and most of those smaller than Charon. As for what the total mass of the cloud is ????? I don't think there's even a good basis for making an estimate.

      What this is about is that sharp edges are almost always an illusion of the way you are classifying things. We know there's stuff in the area called the Oort cloud, but the name is an attractive illusion. We don't, e.g., see those comets that never come within Uranus' orbit, but they almost certainly exist. And saying they live in the Oort cloud is ... well, they spend *most* of their time out there, but that's because of the way orbital mechanics works. Anything with an eccentric orbit is going to spend more time further from the sun than closer to it. This is even true of Earth.

    This story is another perfect example for why the "settled science" academic approach absolutely fails to produce a rigorous result, in practice. We need to be systematically tracking controversial science claims on a social network which is dedicated to crowdsourcing this information.

    It also demonstrates -- once again -- an overt bias against the Electric Universe amongst the scientific community and science journalists. This is really straightforward, guys. Let me explain.

    Alongside the core scientific claim that cosmic plasmas should be modeled as laboratory plasmas, the Thunderbolts Group has also proposed that the earliest human stories are best interpreted through the lens of plasma physics. And although there is not actually a consensus on these interpretations, what some comparative mythologists in their group have concluded is that the best way to explain the earliest stories mankind told -- mainly the mythological archetypes -- is with the suggestion that a foreign star entered into our solar system in human-historical times.

    Notice the remarkable similarity in the two claims. We really have to dig into the very fine details in order to discern the differences between this mainstream science claim and the Electric Universe claim.

    But, also -- importantly -- notice that there was no immediate labeling of this mainstream version of the idea as "pseudoscience", even though the two claims are basically the same -- and -- more to the point, imo -- no demonstrable realization amongst the critics of the Electric Universe that this is what they are claiming. What I have observed is that people are against the Electric Universe brand -- not the idea itself -- for if a person can be convinced that some sort of foreign incursion has occurred in recent human-historical times, the suggestion that we can then interpret the earliest human stories through the lens of this idea is a very short leap of imagination.

    Put another way, people are dead-set against an idea which they don't really know much about. This sort of behavior is not in the spirit of rigorous science, and it can actually lead to tremendous confusion in the sciences, for it institutionalizes a lack of rigor and biases into this process which is widely regarded as secure from such things. And, to be clear, this problem is far, far bigger than just the EU; this lack of rigor is occurring across all of the scientific disciplines. There are some controversial claims -- e.g., the work of Dr. Gerald Pollack on water and gels -- which is routinely coopted by the mainstream, for the simple reason that not even the mainstream researchers have tracked the controversial science claim. These mainstream researchers generally have no idea that they are vindicating or copying other peoples' work -- because we've yet to build out the tools which would track these claims. The information is all spread out, and lacks a system of organization which can facilitate crowdsourcing and discovery.

    We really need to think more deeply about the implications of the "settled science" approach to science, for it really seems like a factory for mistakes which can, in theory, cause us to spin our wheels endlessly.

    People will of course howl because I said the "EU" words, but if you really want to see substantial progress in the sciences over your lifetime, you'll think more deeply about the more general case, and you will favor the approach which results in a more rigorous scientific result. I invoke the Electric Universe to make my point, but this problem is truthfully much bigger than any individual disagreement in the sciences.

    It's just a conceptual label. The core claim of the Electric Universe -- the most important -- is simply that we can model cosmic plasmas as laboratory plasmas. Astrophysicists disagree, and instead model them as fluids subject to gravity. Yet, there is no fluid model which can ever accurately explain the behaviors of electricity and magnetism -- so where we see cosmic plasmas conducting, realize that the models in widespread use by astrophysicists today cannot explain this. By contrast, astrophysicists have rigidly stuck to claims that Debye shielding and quasi-neutrality undermine the notion of electricity in space. The recent announcements that electric currents travel along AGN (black hole) jets is an unacknowledged admission that Debye shielding and quasi-neutrality are meaningless conjectures. And those of us who have paid attention to concepts from the plasma laboratory understand that plasma double layers will make Debye shielding and quasi-neutrality meaningless (double layers are what allow the formation of complex macroscopic charge structures in plasmas). But, even though double layers have been definitively observed within both the plasma laboratory and even the Van Allen radiation belts, astrophysicists have refused to classify them as astrophysical entities. There have been a number of observations in recent years where scientists expressed surprise by some observation which was readily explainable with laboratory plasma physics concepts like double layers.

    Those who are following the debate can see clearly how this is playing out; those who refuse to track it lack the context necessary to judge the debate's trajectory -- and these are the same people, imo, who have come to accept space as mysterious. Much of the mystery is actually introduced by the idea that gravity is dominating at the larger scales. The electrical cosmology approach generally treats gravity as a localized force which becomes irrelevant at the interstellar scale.

    The debate over electricity in space is merely a piece of a larger puzzle which speaks to our awkward interactions with scientific claims. That's at least how I view it. It is not the end of the story, and there is a lot of progress which can be made from merely studying the ways that people interact with scientific controversies. This is what I've been doing for 12 years now, and it's how I will design the social network which will eventually fix these problems.

My approach was to embed myself into the Thunderbolts Group, and then over the course of many years, I ran their claims directly against their biggest critics + the public. By observing the reactions to the same claims, many times over, you start to observe patterns. The point is not to say that this is all that is important; the point is that the social processes play an inordinate role in how people come to these conclusions.

    In my opinion, a huge aspect to this problem is the institutional aversion to telling certain awkward stories that relate to these topics. The mistaken assumption of empty interplanetary, interstellar and intergalactic space is perhaps a prime example of a story which academics and science journalists seem to treat as sort of "rated X" insofar as they generally refuse to place any importance on it. Yet, it can be traced back to the selection of numerous theories in the early 1900's. For example,

    "Alfven's proposal of a galactic magnetic field met with widespread resistance (if not scorn), as it directly contradicted the prevailing wisdom that a vacuum filled interstellar space."

    Eddington explicitly refers to the assumption is his choice of models for powering the Sun:

    "Since we are limited to energy liberated in the deep interior of the star, extraneous sources of supply are ruled out, and it is scarcely possible to escape the conclusion that the supply of energy for future expenditure is already hidden in the star. Energy, however, cannot be successfully hidden; it betrays itself by its manifestation as mass. Energy and mass are equivalent, and we know the masses of the stars."

    Although I don't have an authoritative source on hand, it can also be shown that Sydney Chapman used the assumption to reject Kristian Birkeland's proposal that the aurora originated with the Sun.

    These are remarkable historical observations insofar as we today know that this assumption was incorrect (And more than that, the mistaken assumption was hiding from Eddington an alternative potential power source.)

    The thing about this is that it's rare to see anybody connecting the dots between this former mistaken assumption and the theories which "won out" as popular today -- yet, it is also remarkably easy to show that it did in fact play a part. And there can be little doubt that even Einstein's work could also be implicated as basing on it, for the first instrumented probes were not actually sent to space until 1958 -- 3 years after his death. So, can it be that Einstein was simply working with what he had available to him? The question would seem to be valid, for once plasma is introduced into the conversation, then we can without a doubt formulate alternative hypotheses for all sorts of cosmological observations.

    The mainstream would be wise to start telling the story of this mistake, for it is extremely important. I try to explain why here.

For your theory to be correct the theory of gravity has to be completely wrong and it clearly isn't. So you need to come back with proof that you theory is at least as good as gravity in all areas that gravity is useful and can therefore replace it entirely or reconcile the parts that contradict gravity before it can be considered a viable addition to scientific knowledge".

    In detail:
    More correctly the "Electric Universe Theory" is a form of mysticism trying to pass off the idea that ALL astronomical phenomenon can be modeled simply as electromagnetically active plasma as science. This is incorrect as many phenomena are better modeled by other theories (notably gravity). That some things can be accurately enough modeled as plasmas doesn't change that most things cannot.

    The problem is that the underlying assumptions contradict the very useful theory of gravity. General relativity works very well and is empirically verified by things like GPS satellites. Thus in order to replace GR a new theory must either mathematically reduce to GR in the cases where GR has been empericly verified, or produce equally good predictions covering those case. In addition it must also eitehr make the math simper to perfom, or have the ability to predict things that are different from what GR predicts and have those predictions empirically verified.

    Were EU theory science it would make the uninteresting claim that some things are plasma and can be modeled as plasmas, and maybe some things that aren't intuitively obviously plasmas are (surprisingly) also plasmas, but that most things still aren't plasma. Because it is mysticism instead they claim that all things are plasma (because complex nuanced positions are hard to sell), point to the known limits of GR to claim GR must be wrong (whong as in totally wrong not merly incomplete), the known successes of modeling objects as plasma to prove that EU works all teh time (rather than sometimes if you cherry pick the conditions), and hand-wave the gap between those two points and the conclusion that "therefore everything is plasma, gravity is completely wrong, and you can be smarter than so called "scientists" is you just buy my book that explains it all".

Do you know what stopped the ridicule? The Germans took Goddard's invention and attacked Europe with 3,000 V2 rockets. Those V2's had all of Goddard's key inventions within them, because as the American public was mocking Goddard, the Germans were intently listening to everything he said.

    The Electric Universe does not begin in the same place as conventional astronomy and cosmology. It starts by recognizing that the cosmic plasma models widely applied by astrophysicists are wrong -- and once the models are corrected to reflect our laboratory observations, the dark matter problem goes away. From that vantage point, options open up for how to proceed to explain gravity. But, Anthony Peratt's galactic simulation with proper rotation curves explains what is happening at the largest scales without need for any dark matter -- meaning that it essentially meets your criteria above (just not in the way that you imagined).

    The point is that we have "potential wins" on both sides of this debate. It is not a one-sided affair, for instruments designed to detect dark matter have grown a million times more sensitive over the past 15 years -- meaning that dark matter is starting to look like modern cosmology's dead end.

    You could have reasoned your way to the same conclusion without having to build all of those instruments, actually, by simply considering the ridiculous scales we are talking about here: If the Earth was just an inch from the Sun, the next nearest star would be a stunning 4 miles away (!). Simple logic and some very simple algebra is screaming at you that gravity is a "localized" force, starting at the interstellar scale.

In the early days, plasma physicists would etch electrical discharges into various media like paper, and a very common form was a ring of vortices. This is a typical shape that electricity takes when it travels through gas: The plasma filaments break up into a ring of smaller filaments (vortices in 2d cross-section). Anthony Peratt has written a couple of papers detailing these "instabilities". In fact, some people refer to them as "Peratt instabilities".
