    the UFO fans are excited with the general acceptance they are getting from mainstream media but well , attention falls short . Like some report on New York Times and it is reported to be nothing ground breakin' . People reading this thread will remember me obliquely referencing some blog . As boring times keep on , ı was over there and wasn't much surprised to read they are downgrading , as in no more Star Trek . But quadcopters as in bog standart drones , a red meteorological balloon that plays Nena and you have be like at least 40 to get this and ı have never understood whatever that song tells . And also stuff built for tuna hunting , which might be for real for all those cans of ton balığı ı see in shops . Impressiveness now limited only to that they seem to be quite high in altitude for their respective classes and they have no visible means of support . As in unclear who and what deploys them .

    oh , nothing actually mysterious . The venue is USN's training grounds where also F-22s roam . New radars snooped on , required for creating chaff and jammers and whatnot . American problem then being America being number one . People can not accept Roooshia at their doorstep , so all sorts of distortion , because everyone in Pentagon knows the stuff is deployed from whatever Akula is on patrol at that moment . Because evil stupid Russians have broken Nato codes and have introduced a new Akula class , when they had one already named so by the West ! Trump and his voter base and stuff that might go wrong . Hence , the blog's attitude . A thing to consider here , that ı was browsing that place with a computer in the webcafe and it seems to be more designed for phones ; so much that ı can read the comments section with the tablet . So , some mysterious rich dude getting high with playing Uncle Sam , bkz (Turkish short form for also check) the Colorado affair with drones planting potatos or whatever or mysterious drone airfields which were previously owned by a drone company of some brilliant billionaire or whatever . Why don't they just be Bill Gates and design coronaviruses and kill people and face justice in the international courts as some right wing MP in the German Parliament has asked for ? That Akulas are good can not be front page news , but will be always reported yearly for budgets hence more layers of mystery . An USN ship was seen , once , in the area but USN can not identify the ship ... lt wouldn't be a natural response for me , but some commentator says the Philidelphia experiment ! Would say a Gearing myself , but then it came to me that the blog had already identified subs and Cuban crisis . So , it is actually a fleet snorkel , a most basic conversion of WW ll boats with a weird fin/sail shape , because ı have one single book on submarines and one picture in it of S-302 USS Sabalo . Because if something goes wrong and it needs to surface , because Commies can not sail ships or tie their shoes , Americans will be confuse and ask home what to do . Because Cubans modified a Foxtrot , Whiskey or Romeo and they invariably sail near Turks and Caicos on their way to and from stealing American tech .

    this much people would have already deduced themselves if ı had provided a link but am r16 and like am to be instructive so ı decided to read about the famous experiment ... Because , my late father loved maps , maybe because he would have liked to travel and this world map on the wall shows British possessions in blue and you have to be like lucky to notice Bermuda , while checking the route from Cuba . Some surprise ! This pesky internal voice of mine had always told me that it was the cruiser of the same name , but it is quite a masterpiece or whatever . Eldridge or whatever , a little sub hunter while there must be something like aldritch or whatever to describe the likes of ctulthu ? So , some guy who looks quite like an US Goverment man (with the bonus life history of being an archeology guy in Central America like 20 years before the last Indiana Jones movie) is doing his thing of writing a fake history for UFO loons when 3 uniformed navy guys meet him . A book he has written has been posted to an admiral , with "annotations" written on the margins ... This is some crime that ruins books but it is like odd . 3 different pen colours , odd capitalisation and punctition . (No , Philidelphia Experiment was not a success and it didn't take me back .) The Goverment guy then supposedly identified some other lunatic who had sent him funny letters back in the day . The whole Experiment narrative then starts with this . Because for credibility , some Varo Corporation (forefront of tech and like invented chips for TI , because all UFO stories tell being human is dumb and mankind can not do anything without alien intervention) printed a limited amount of books . So , three "gypsies" A , B and Jemi talk of the war high above . LM good / SM bad . The bad ones are easy , with this Sade guy , ı do have to check when Lockheed Marietta became a thing . Loveable people vs excrementy people or long men vs short men are also possibilities . You would have to remember all aliens were short , before certain short people showed some feats of endurance in places like Vietnam , being short would no longer be proof of being easy to beat in war . Accordingly the good aliens are short these days , as far as ı get from some site where ı be trawling books . The Roswell Autopsy fakes ? These are our benefactors assigned by the Galactic Federation against the Lizards who merely control 21 solar systems , but the lizards were foolishly let in Eisenhower in 1954 and lizards killed JFK , too . And while at it , let me translate Jemi for you , Japanese and European Military lntelligence agencies , and while you would have a better candidate , these were the years when the USN was still able to have some office building that oddly looked like a swastika to any Russian satellite that passed above . Then a very real book that tells me Eisenhower was very wary of the Sputnik and the American flopniks that followed and the counter attack in the media consisted of nuclear submarines of the USN ... See , the Goverment guy was calling rocketry as silly , satellites were worthless and like the Soviets had already launched one , years before 1957 the year these events were taking place , the very year American intelligence had learned this Korolev guy was doing quite allright and Moscow had no intention of granting any mercy to lke so that America could be the first in the world to orbit with an artificial satellite in 1958 , the year of Geophysics . People to blunt the impact , which is also the starting point for February 45 , winged and piloted V-2 , which is a tar and feather offense in places . America invents nuclear subs , Russian Novembers are coming , so everybody can make a submarine but only Americans can teleport a DE ... Running out of battery charge , will also see whose MiB is the real McCoy ? How it is going keeping secrets out of fools' hands by diligent people ?

    Finding the "Planet 9" black hole with a fleet of spaceships
    A fleet of tiny spacecraft could prove the existence of a primordial black hole in the outer solar system – according to two independent proposals. The primordial black hole could be playing the gravitational role of “Planet Nine”, which is a hypothetical world that could explain the unusual orbits of certain Kuiper belt objects (KBOs) in the outer Solar System.
    Orbits of these KBOs suggest that a body a few times more massive than the Earth currently resides about 500 AU from the Sun towards the constellation Orion. Searches for Planet Nine have come up empty – but this is no surprise because at that distance, even a large and reflective planet would be barely detectable with the kind of wide-field-of-view telescopes used for large-area surveys.
    His proposal is a more modest version of the Breakthrough Starshot project, which aims to send ultralight (about 1 g) probes on a 20-year journey to the nearby star Alpha Centauri using an earthbound laser array to boost the spacecraft to 20% of the speed of light (0.2c). Using a similar system, Witten reckons a 10-year journey to 500 AU could be achieved at 0.001c with much larger spacecraft (about 100 g) – necessitating a less daunting feat of miniaturization. This is still 20 times the speed of NASA’s New Horizons Pluto probe.
    By scattering a host of such probes in the general direction of the hypothetical black hole, a lucky few might pass within tens of AU of the object, accelerating slightly as they did so. If the probes send regular, timed signals back to Earth, the gravitational field of the black hole would cause a lengthening of the interval between pulses.
    Witten calculates that to detect the black hole using this scheme, the probes’ timing measurements would need to be accurate to about 10^-5 s over the course of a year. This is well within the abilities of existing atomic clocks, but it is hard to imagine how such devices could be squeezed into 100 g spacecraft.​
    Physicsworld arXiv preprint 1 and preprint 2


    Gravitational pull: the six most distant known objects in the Solar System with orbits exclusively beyond Neptune (magenta) all mysteriously line up in a single direction. Also, when viewed in 3D, they tilt nearly identically away from the plane of the Solar System. Caltech’s Konstantin Batygin and Mike Brown have shown that a planet with 10 times the mass of the Earth in a distant eccentric orbit anti-aligned with the other six objects (orange) is required to maintain this configuration.

    Yeah, a company called Swarm (IIRC) builds vehicles about that size, more or less. They launched without an FCC license a while back and got slammed for it. They've since bounced back and are getting ready to deploy their constellation.

    Yes this is quite the scandal. In his resignation letter, he mentioned that he made a mistake in his efforts to speed up the lunar landings and that he has to pay for it. Scuttlebutt is that he let one of the companies bidding on the lunar lander contract see the submission of their competitors.

    What's especially shocking about this resignation is that next week, NASA will once again launch humans into orbit from the US on American rockets. SpaceX's Dragon/Falcon 9 stack just cleared their flight readiness review and will blast off to the space station on a test launch with 2 astronauts aboard on the 27th. Very exciting!

    Virgin Orbit also surprised everyone by announcing they will attempt their first orbital test launch tomorrow. The payload is a dummy and they will not be livestreaming it unfortunately so there won't be much to see.

    A UK startup is gearing up for their first launch out of the Scottish highlands.
    Spoiler :




    It is interesting to me that they are using hydrogen peroxide and kerosene, which was the same fueled used by the last British rocket program (Black Arrow) nearly 50 years ago. Almost no one else uses that particular combination either. Their choice of launch site will heavily restrict the orbits they can target but I believe it came with generous subsidies from the government.

    Why? Better, where? The only clear area is SW and that is a buy shipping zone. Go any other direction and they are dropping boosters on populated areas.

    so , what was the Philidelphia Experiment ? Will be non-linear a story . ln timeline and stuff .

    it is essentially a fusing issue and ranging question . Victor Belenko , in his book , said SR-71 was so fast that an head-on missile shot would take the combined speed to extremes and the AA-6 Acrid would have no time . Well , the solution would be firing from the back . Had fun designing backwards . Manned "rocket" again , Mach 2.0+ for ordinary thermal limits of aluminium / needs no 360 degree vision / needs no airfield performance because / V-2 is a 7,92mm bullet , Bell X-1 is a .50 caliber . Hogwash that Blackbird was stealth as every mission into North Vietnam was fired upon , so when one comes in... just launch and turn behind . Not that much of an issue now that Russians placed quite good pilots in Foxbat cockpits and they mostly managed to keep their 180 degree turns to entire East Germany , most of the time . Run high , run fast and you will be anything but agile . Then a geographic location as Russians would naturally lob a nuclear SAM and explode it on remote control , letting SR-71 fly into the fireball . So , China and Commies and America upgrading Monroe Doctrine and becoming primus inter pares in China because they would make funny faces and sounds and die out of jealousy as Britain already had lndia . lf a Blackbird was to be downed over China it would be like gross !

    see , that is why ClA needed releasing radioactive stuff , Cesium ı think from the exhausts , you could really find it on the web . So that it becomes a cloud and stuff and traps incoming radar waves . So when this rocket guy comes behind and fires his air to air missile , he won't have ranging data and he might still have fusing issues as well . This about late 1950s . Current day BS about this happens to be F-22 in Red Flag and you see it by eye but can't use your lR homers , because radar stealth (as the missile awaits range data to be launched within parameters) .

    how do ı get the idea ? Wikipedia page leads to external site which then reports on USN reporting in about 1996 that they didn't investigate Stealth with the Experiment ... You know the drill , they are naturally lying . So , if radiactive stuff was to screen things , maybe they have chests on deck and open the lids ? Painting the hull perhaps ? Naval fighting in Guadalcanal was a hell of its own and torpedoboats are small enough . But guns , and heavier as they come , have an utility of their own . Sneak , shoot and sink , rinse and repeat . Hey , that rinse thing reminds me of wash systems Cold Wars ships had against fallout ! What if you had tanks of stuff that you hosed off the ship , forming a water screen ? Of course don't have the haziest idea on how much stuff you would need , but having a large ship would help and big ships maintain speed better in bad weather and what not , say 3 hours of steaming at 30 knots means like 150 kilometers or whatever and what were radar ranges those days again ? No , we have just began because the radioactive stuff has to come from where ? V-2 was refused by the Brits because with cordite and stuff they had it would have to a 60 ton weapon to hit Britain from Europe and it could never be deployed in the field . At one point there was some real crisis as the bomb design was too heavy and large to fit in the B-29 , production of which was a colossal endevour , easily matching or dwarfing the Manhattan Project already . Cruiser might have lost a turret or two , not only to the rocket with you know what and systems like fueling but extra electronics to make sure it would have some accuracy . One run and no more Tirpitz , one run and no more Truk .

    got a bit of compliments and ı asked my weird friends essentially what % true and they said "We're all monkeys, how would we know?" Then ı also discovered the weird airbrake of F-15 was designed that way to let the guy parachute safely , you know the guy who sits like next to the engines . Proud of me they were . Took some real brains to get that working , let me tell you . How is it going with keeping secrets out of fools' hands , one asks and it obviously goes so well .

    and yes , USN made the fake story of Eldridge to deny patent rights to Lockheed ...

    Can't they reach orbit by launchin' outta East Anglia? Or all of that coast above the Fens? Over the North Sea. Still busy but it's a long way till the Danes.

    Cornwall is further South than East Anglia and that is I understand
    of some slight benefit regarding geo-stationery orbits.

    Wouldn't using hydrogen peroxide and kerosene be a relatively safe and stable fuel choice? What's the problem with it?

    There's a few things at work -
    A couple of years ago the UK tried to create a national spaceport by choosing and upgrading an existing airport. They had a list of finalist facilities but then before they made the final down selection, they basically said that instead of picking one winner, they'd let multiple places upgrade to spaceport status and would provide some limited funds to do that. This lead to a mini boom of space port construction as multiple places want in on the action. The other thing is I believe Skyrora is building facilities exclusively for their own use in the highlands, and the Cornwall facility is being built as a public-private partnership to host Virgin Orbit and potentially others. Corrnwall also hosts the Goonhilly Earth Station which is a majorly important ground station for communicating with satellites in orbit and deep space.

    The only two orbits available to ground-based launch facilities in the UK are polar and retrograde because anything else (low-inclination or geostationary) would require overflights of other countries. Virgin Orbit gets around this limitation by the use of a 747 as a carrier plane for their air-launched rocket. They take off from a runway, fly out over the ocean, point in the right heading and release the rocket which then zooms off to space.

    Virgin Orbit's first orbital flight is actually scheduled for today, coincidentally! No live stream though. :(

    The US has experienced a similar boom in spaceport construction but none of the facilities have hosted any launches yet though the Spaceport America in New Mexico will host Virgin Galactic flights soon. This hasn't been much of an issue for the spaceports because despite the lack of launches, they have proven to be viable economic hubs for space activities. A lot of startups will cluster in these facilities because of their unique ability to host certain hazardous chemicals and tests and such.

    The UK and Australia are currently in various stages of catch-up as they scramble to provide some funds and facilities to space and rocket start ups now that they've seen the wave crest in the US and NZ.

    It is relatively low performance and rocket-grade hydrogen peroxide is fairly dangerous itself. One big benefit is that you don't have to have cryogenic refrigeration as you do with liquid oxygen and you don't have to worry about LOX boiling off as you sit on the pad.

    Would a black hole in this solar system only rip apart virtual reality or literal reality? In other words, is it just a mathematical posibilty, or is there a black hole?

    How destructive it would be depends on the size. If there is one, it's big enough to throw comets around but not big enough to gobble up everything.

    The first thing that would be noticeable would be the gravitational effects on all the objects in the solar system. A black hole would rip apart the solar system just like a massive star could. Since this isn't happening, any hypothetical black hole in the solar system has to be quite small.

    A black hole has the same effect on it's environs than a same mass star would have at a distance. It's only if you get too close it starts to spaghettify you. If it's small enough you may never know it's there, that said, such tiny mass black holes have never been spotted.

    How small could a black hole be?

    Nobody knows, because you would need a quantum theory of gravity to answer that. The expectation is that the limit is somewhere around the Planck mass (22 micrograms).

    IIRC Hawking predicted that they can be very small and the smaller they are the faster they lose mass due to Hawking radiation.
    So, the smallest ones have quite short lifespan and eventually disappear, probably with explosion.
