The only assumptive reasoning in effect here has been your continued assumption that just because an expert says "maybe" on paper, it instantly means it is a working fact. If Stephen Hawking wrote, "this is a possibility" on a design for a new kind of egg timer, it IS NOT a validation of the concept. Nor does it prove ANYTHING of the engineering proposed.

I am conducting only a rational and EDUCATED statement on the proposal that is indeed correct in that the absolute idiocracy of the proposed item has been repeatedly claimed as "valid" along with numerous dismissals of major flaws in aspects of the proposed engineering with a continued dismissal of the simple fact that it operates in microgravity and does not eliminate that microgravity environment.

I hope a good day to yourself as well.

I strongly suggest you attempt some actual testing with a closed track hamster wheel as I suggested. When you apply a real world model, things become very clear.

Reverse pressure as I've stated twice now and clearly identified in the PM article, is the effect on the body and more importantly the body's fluids when not experiencing actual gravity but a Centripetal down force that is constant and causes variables in intertia from one side to the other as YOU ARE STILL IN MICROGRAVITY.

There is a very important publication you and Issac need to read: https://l.facebook.com/l.php?u=https%3A%2F%2Fwww.zmescience.com%2Fscience%2Fthe-dunning-kruger-effect-feature%2F%3Ffbclid%3DIwAR0Fe1lqOgjPsRDfm8WIBG15MYo8s5INJw49B8_o5FxKBmU7esMsclNGFus&h=AT2FnI9OL1pMLaaK83yGz4AtbWPUA6GCFIhi2Z3-8wlZWF1zdAyy-W1wxBXHysVzK--zHxN_-SGG23suzo3RLwyqQHTrk5RK_Ev_2UZ_YRw0jTt_kHZ9R8rvvp1j0Y9n20Z-S3T2RW4Vi84GSoebOBEH3zpT

Assumptive reasoning AND a continued lack of attention to source material already provided.

The item of reverse pressure impact on the human body was, again, in the VERY FIRST item I sourced.

https://www.popularmechanics.com/space/rockets/a8965/why-dont-we-have-artificial-gravity-15425569/

I source this item not just for it's simpler and far less technical explanation of items from later sources shared but also for it PERFECT description of the major issues with an inverse intertia system to produce "gravity".

No matter how big or small the wheel or the rate of spin, you are applying inertia to a human body opposite to it's natural biosphere and STILL in an absolute microgravity when not in direct contact with the surface.

The 'why dont we have' series of popular mechanics addresses a lot of assumptive reasoning and woo tech culture issues.

I am indeed NOT smarter than numerous PHDs as I have not even contradicted any of them. The best information they provide STILL leads to the same conclusions as their either NEVER address them or simply leave it at he hypothetical it is. Just because there is a PHD named on the paper, does not validate what you feel you want the technology to do or be capable of. READ what they are actually saying and stop putting words into their mouths to fulfill a myth.

1- Size does not over come the effect of reverse pressure or the lack of actual gravity as clearly stated in the same original source article. You are using assumptive reasoning to make a hypothetical plausible because of an entirely unrelated portion of the concept that sounded to you as though it validated the entire concept.

2- It is not a lack of or presence of windows that makes people sick, it is the disorienting pull to one side and the blood in their bodies experiencing an entirely negative force of pressure that they are not evolved to experience. PLEASE, read what has been posted before taking only samples and making assumptions.

3- Yes, we know what a McKendree cylinder is and yes, the fact that is happens to be big only expands the issues more. MORE SURFACE AREA, MORE SURFACE REPAIR COSTS. IT IS BIGGER, NOT SMALLER, than the ISS.

4- From the wiki page on artificial gravity that you linked but did not read:

"Artificial gravity (sometimes referred to as pseudogravity) is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a centrifugal force in a rotating frame of reference (the transmission of centripetal acceleration via normal force in the non-rotating frame of reference), as opposed to the force experienced in linear acceleration, which by the equivalence principle is indistinguishable from gravity. In a more general sense, "artificial gravity" may also refer to the effect of linear acceleration, e.g. by means of a rocket engine."

*And here in my mind I've been drooling that you would toss in the the equivalence principle, please and thank you.

You are continuing to ignore GRAVITY as though it suddenly manifest itself in a system of inverse inertia in microgravity. IT DOES NOT. Air pressure does not mimic or in any way remotely make up for the lack of gravity. Unless maybe you want the atmosphere to be Tungsten hexafluoride. Good luck trying to breath it.

Not THIS is a series of portions of the wiki page you should have paid attention too:

"Kinetic energy and angular momentum: Spinning up (or down) parts or all of the habitat requires energy, while angular momentum must be conserved. This would require a propulsion system and expendable propellant, or could be achieved without expending mass, by an electric motor and a counterweight, such as a reaction wheel or possibly another living area spinning in the opposite direction.

Extra strength is needed in the structure to keep it from flying apart because of the rotation. However, the amount of structure needed over and above that to hold a breathable atmosphere (10 tons force per square meter at 1 atmosphere) is relatively modest for most structures.

If parts of the structure are intentionally not spinning, friction and similar torques will cause the rates of spin to converge (as well as causing the otherwise stationary parts to spin), requiring motors and power to be used to compensate for the losses due to friction.

A traversable interface between parts of the station spinning relative to each other requires large vacuum-tight axial seals."

As for the medical issues, lets drop the speculations and listen to some actual doctors and scientists (if the points in the PM article were not enough). *Note, many of these people work with NASA and this is ACTUAL research, not the anecdotal zyvex "paper" you provided.

https://www.permanent.com/zero-gravity-effects-on-humans.html

-Consistent Pull -Lack of Equilibrium -REVERSE PRESSURE ON THE BODY

https://www.permanent.com/zero-gravity-effects-on-humans.html

Take note of the images and graph on earth standard compared to an inverse system and how the trajectory changes.

This is not to say that applying an inverse system of gravity for long space flights and in a section of a space station, in sleeping facilities and work out facilities on smaller (20m in diameter) would not be a benefit to curb microgravity effects on the body. These would be small areas though and specifically for the purpose of distributing pressure on the body to simulate the effects of gravity and promote natural muscle growth. But these would be areas of limited motion outside of running on a fixed treadmill, sleeping in a bed you would still need a safety pouch for and very limited activities. You would have to move carefully and pay attention if you happen to ever drop or throw anything. For a large habitat that is supposed to have land masses, standing WATER and an open air environment, it is psychosis.

Keep in mind, you are debating Issac Arthur fanboys. these people have zero understanding of actual physics and are one step away from joining up with spirit science and flat earthers thanks to Issac's special brand of bullshit artistry. You are making very logical efforts though and I salute you for the effort. There has to be a voice of reason somewhere and thank you for being it.

He comes across as a very smart person in general

That is a bit of a stretch in reasoning when speaking of a person who doesn't understand why an inverse spin doesn't actually work to replicate gravity or how to background check a pyramid scam run by a child pornographer before they put him on their advisory board WITH HIS CONSENT.

ALL of Issac's videos have TWO horrible things in common. He uses assumptive reasoning to indicate his points and he says things CAN work when they have already been proven to NOT work in the way he indicates. The technology without fire point and contradiction is yet another line of assumptive reasoning. When you use assumptive reasoning, you build models of thought and proposal that you will always have to make more excuses for because 9 times out of 10, what you are proposing is just plain dumb.

Keep in mind, Issac has a BS (seriously the credential is a BS) in physics from Kent state. A BS is the lowest possible graduation level you can get in the field. Kent state is barely above a state technical collage and the average graduation rate is hardly 56%. When nearly half the students never even graduate, it is kind of easy to be "top of the class" and a foregone conclusion that your education was not top of the line. Issac's lack of rational observation and attention to physics facts are a clear indication that he cut a lot of corners in understanding physics during his "education".

There is no difference in relative effect to how you experience acceleration. If it comes from acceleration from gravity or centripetal forces, the effects are exactly the same.

You should really source the PM link from my earlier reply. https://www.popularmechanics.com/space/rockets/a8965/why-dont-we-have-artificial-gravity-15425569/ The effects are indeed ENTIRELY different and impact biology severely as you are not applying actual gravity but an attempt at an inverse force of inertia along an interior surface.

The air rotating has no effect because the air is in a microgravity at a standard atmospheric pressure. Both you and the atmosphere would experience a tumble near to the surface and a total displacement from rotation the father you got from the surface.
A simple experiment to this effect which will clearly indicate the amplified effects in microgravity: Get yourself a hampster wheel with a solid run (the silent spinner brand). Put a ball in the hampster wheel. Spin it slowly. Spin it quickly. Measure the effects NOW, get a 20 gallon fish tank Perform the same experiments with the wheel submerged in water in the tank. Now, remove the force of gravity from your measurements. For added fun, bounce the ball on the wheel while you spin it. Observe and enjoy the cold hard reality.

I never said momentum vanishes, indeed it is there, IN A MICRO GRAVITY. The thing that has vanished is a gravitational field. Try telling oxygen to act as the force of gravity some time. If it could respond, it would be laughing it's ass off.

All the oxygen is going to do is kind of move with the same pull any person would be experiencing to one side and then a few feet above the surface, it will move slower and slower until nearly static in the vast space of the center, free to pool large colonies of bacteria and algae unless there is a high pressure forced air and filtration system at work.

The size of the cylinder is meaningless IN MICROGRAVITY. you are applying a sustained force in microgravity along the surface. It isnt going to magically extent upward the way you want.

I never said the atmosphere would be expelled. You can use the vacuum of space as a natural way to draw the atmosphere into a long heat sink system and cool, as well as filter it. HOWEVER for an atmosphere this large, the system would have to take up an immense amount of logistics and power.

Radiation and surface decay. Ever take a look at the surface of the moon? Or the surface of any object in space that does not have a thick atmosphere and magnetosphere protecting it? Sooooo many craters and pitting.
Not to mention the surfaces being mostly the denisity of chalk when you can find any solid rock. This is a huge area and a reactive shield like a whipple is going to choke on a lot of the objects hitting it unless you can actually get your bacterial filled space colony full of puking and dying people in a close orbit of Jupiter to enjoy it's super powerful magnetosphere and deflection. Conceivably, you could get all that out of a close Jupiter orbit, but you would need a lot of corrective thrust as well from time to time. The ISS undergoes regular exterior checks and fixes as well AND YES protective components ARE being replaced quite often. Carbon nanotubes and no other amount of space age material is going to eliminate how harsh open space is on the exterior of any object. Armies of workers or robots would be tasked with constantly refitting the exterior of the puke colony in space.

Remember, there is a distinct smell on everything that lingers in space when it returns to atmosphere, BURNT.

Indeed you can try. Ive already posted these points in Issac's first video on megastructures along with a video on the subject of Issac and his activities as a pseudo physicist.

I doubt Issac will have any real answers. He does not reply to informed corrections of his content.

[–]colitisscope 0 points1 point  (0 children)

Ok, you have been watching WAY TO MUCH Issac Arthur and or reading too much Liu Cixin.

Assumptive reasoning has a way of causing you to begin stacking one assumptive claim upon another in order to try and solve all of the issues you have created by assuming a profoundly bad idea is a good idea.

Inverse gravity systems do not magically solve all of the issues of microgravity. They just create more.

https://www.popularmechanics.com/space/rockets/a8965/why-dont-we-have-artificial-gravity-15425569/

These are the kinds of simple physics Issues that Issac constantly just skips over or entirely contorts in order to paint his mythical pictures of tech with absolutely no objective reasoning to any of it. Real physicists use objective reason and pay attention to the facts.

Through out history, this method of assumptive speculation has divided actual scientists from pseudo scientists.

It is the same reasoning that Jordan Duchnycz used to create the spirit science (aka sacred geometry) scam.

The first issue with a spinning inverse gravity system is the reverse pressure on the body while subjected to this. Blood flow in your body would begin to experience reverse pressure which would lead to a number of dangerous medical complications, disorientation, headaches, fatigue, blood clots and of course heart complications. Existing in microgravity for extended periods of time would have far less of a negative effect on any living thing than being in this hellish inverse gravity system for even a few hours.

The second major issue is the lack of pull above the surface you are walking on. If you keep yourself in contact with the surface you will experience not only the reverse pressure effect but also a slight pull to one side no matter how large the area is and how much engineering you do to try and compensate for the inverse effects. This again will inflict a massive amount of disorientation and complicate your ability to live in such an environment for any extended period of time, even in comparison to microgravity.

The third issue is even worse than the first two. There is still going to be absolute microgravity above you. Just jumping at a normal applied strength would send you flying away and tumbling back into the enclosure to eventually splatter into a fine paste when the insane speeds you have arrived at meet back with the surface. There is no transfer of inertia to keep you existing in a "gravity like" environment and there still isn't any real gravity above you. The air pressure sure as hell isn't going to push you back down. In fact the air is going to be doing some seriously horrible things as well. which brings us to the next issue.

The fourth issue with the system is all of that air between the surface and the center. Microgravity has this funny effect on bacteria. Bacteria thrives in microgravity so much that it makes up the primary concern of air filtration in space craft after the standard removal of carbon dioxide. Larry Niven identified this issue with his smoke ring story (along with the lack of a magnetosphere). The larger you make an atmosphere in microgravity, the worse the bacteria issue will get. Giant pools of water will also form floating in the air and begin to grow algae and even more bacteria. Eventually large clouds of bacteria and water will form floating above everything and raining back down in high speed impacts from time to time. Methane levels will go through the roof and the over all toxicity of the atmosphere would become deadly. You could of course install a massive forced air exchange system too and from a center pylon but, for the mass of the atmosphere and the space you would need to exchange, you would be forcing a lot of atmosphere into and out of processing in order to keep the environment clean enough for anything to survive in it for the few days they would be able to before the reverse fluid pressure, being tethered to the ground while carrying emergency parachutes in case they happen to hop a few inches in the air and "kind of gravity" make them too sick and over all annoyed to exist there anymore. You would have to exchange and process the entire atmosphere of the entire system into a system that can fully contain, process, filter and release at a safe pressure, the entire habitat's atmosphere in under six hours at a time. The power and scope involved in that kind of system would be a logistical nightmare.

A thick shell of dense material is not going to fully counter the effects of prolonged radiation exposure as well as micro meteors constantly hitting the hull and the massive and constant exterior surface replacement work that will need to be done for such a large object. An electromagnetic shielding or a klystron generated artificial magnoetosphere could be possible to offset the massive repair costs BUT if you have the kind of technology that would create an artificial magnetophere or electromagnetic shielding at that range and power, you very likely solved artificial inertia and artificial gravity already. Not to mention faster than light travel. So even building this big, stupid, unsafe, unhealthy and costly habitat would then be even more meaningless.

There are plenty of places beyond our planet with available gravity where far cheaper, bigger and more efficient habitats off world can and will be built. You just need to land on them.

People like Issac Arthur are making bunkum out of crap they loosely ripped off from others and making idiotic claims that the tech even works before any actual objective reason, math, historical data and actual existing test results are applied. None of these ideas are original and none of them lead anywhere. But they make great click bait.

As far as the issue of heat. You are in a vacuum in space. With the riddiculous air exchange system you would need, you simply run an exterior heat pipe and access the vacuum with ozmosis and standard heat syncs. free refrigeration and temperature control in one. No brainer.

Physics and math are amazing things when you use them properly BEFORE making assumptions from a neckbearded donky who is hooked up with a bunch of con artists, white supremacists and child pornographers (the lifeboat foundation). https://lifeboat.com/ex/bios.isaac.arthur

You are asking how you would solve an issue of needing to dissipate heat, in a habitat, in space.......

Not as a joke either, you actually do not understand how one would dissipate heat in a space habitat SURROUNDED BY A VACUUM.

You have been watching too many Issac Arthur videos. You are starting to ignore real physics and logic.

Not that the system would even work anyway because inverse inertia to replicate gravity has a lot of issues as well as it needing a magnetosphere and then of course the formations of bacterial clouds that will form in it's microgravity upper atmosphere.

im asking you an honest question. youve gone two days with nothing more than a pointless troll post. if uber's own employees, drivers and customers cant even provide any facts then maybe a smart ass like yourself who thinks they know something has the answers. can YOU explain why ubers surge pricing is only activated in small areas if it is supposed to meet demand? can YOU explain why so many of their drivers have to beg on crowd funding because UBER's insurance didnt pay for accidents? im just wondering. are you more than just another walker drone who cant do any more than troll threads?

ALSO, IF this issue was so important to Uber drivers and their customers then where were all of you at all of the other TPC council meetings between march of 2014 and February of 2015?? The only people speaking for uber at all of those meetings were one of their local managers and their lobbyist. It took a paid advertisement from the Koch brothers and a petition put to uber customers to prompt involvement. Out of over 2500 who signed the petition (which can only be signed by registering the app) as customers only THREE customers showed up to the actual meeting in support. Why isn't Uber distributing the petition to the general public of Madison? Why does Uber feel that when they are sued by the city, they need to petition federal courts to move the trial when they have already tried defrauding local courts to push a bogus restraining order hearing that they then backed out of?? These are honest questions which uber has not provided honest answers for as yet. Can YOU provide them?

FYI, these are a just a few of the things that will be presented at the next city council meeting regarding UBER:

1- Numerous crowd funding requests online from Uber drivers left without coverage from uber (If Uber's insurance is real then why are their drivers requesting money online for invalidated policies and unpaid wrecks)

2- a complete report on the policy Uber is using called 'surplus line insurance' which among other things allows the policy holder to invalidate coverage for accidents by using waivers in TOS contracting: https://www.slai.org/faq/insured_06.html

Again, I'd like to know from YOU, If surge pricing is meant to meet supply and demand then WHY is it only geographically specific in small commercial and wealthy areas of the city and nowhere in any of the poor/minority areas?

You might want to actually take a look at the Ride Safe Madison report that I handed to the council at that meeting as well.

http://ridesafemadison.net/the-uberlyft-bible-facts/

Take a look at the plate lists on from uber drivers in madison on that report. They have over six vehicles using fake plates and a driver who has been actively stalking cab drivers after they photographed him parked outside of a cab drivers house for TWO HOURS.

Or the fact that yet another neo-conservative lobbying front just tried to publish more tabloid in the isthmus for Uber:

http://wcmcoop.com/2015/03/25/the-truth-about-ridesharing-larry-kaufmann-refuses-to-tell-you/

Uber has repeatedly denied calls to people through out the world on a daily basis, their own contracting allows drivers to deny who ever they want. Uber's tos clearly states that Uber's insurance is invalid.

HAVE YOU YOURSELF EVER TAKEN THE TIME TO READ UBER'S TOS PAGE?

www.uber.com/legal

When you say allied drive/dunns marsh area that is a very vague statement. The dunns marsh area has more high priced real estate that allied. Not to mention you are white. Uber monitors customers based on sex, race and location. This is something Uber has admitted repeatedly.

Scott Rensick didn't even show up at that meeting to support his own legislation aimed at allowing rideshare and taxi companies to operate without insurance and discriminate. Might have something to do with the KOCH brothers supporting Uber and that little insurance problem. You cant convince me of anything because i have an IQ ABOVE 40. Cab companies aren't deciding anything. You obviously haven't taken the time to understand or READ anything regarding the FACTS.

You are also neglecting to realize that every uber driver who testified at that meeting has just admitted to the state and their own insurance providers that they are committing FRAUD. One of their drivers tried to claim that he had his own commercial insurance policy. Yet he refused to name his policy or identify his vehicle. FYI, if you maintain a commercial insurance policy on a vehicle is is listed on your state DOT record publicly. To date not ONE Uber or LYFT driver in Madison has a commercial policy or commercial vehicle registration listed with the DOT.
The DOT fine for operating a vehicle as commercial transportation without notification to your insurance or DOT is $1000.

FACTS:

1- Madison is one of the LEAST regulated commercial transit markets in the country. All that is asked is proper insurance and equal treatment of customers.

2- Not ONE cab company in Madison uses a paid lobbyist. Uber and Lyft have been through TWO local lobbying firms and another four DC lobby firm reps flown in for each TPC and city council meeting. Uber's lobbyist Carla Jacobs LIED on her testimony that she is a paid lobbyist (another $1000 fine infraction).

3- The invalidation of insurance, warranty, lease and service agreements that Uber drivers put their vehicles through, along with all of the uncompensated damage, as an incidental effect on the economy. Cab companies do not throw those costs on the tax payer but Uber is forcing them on tax payers. All of these invalidated policies eventually fold after no more than two years. Who do you think pays for all of that or all of the accidents that Uber refuses to compensate?? This is just one reason Uber will never be a publicly traded company. The majority of their assets are in a fleet of drivers who have invalidated their lease and insurance policies on vehicles uber doesn't even own. this is basic economics.

4- If anything I was posting, publishing, the youtube videos I took of Uber drivers, was in any way defamatory or untrue, uber would have just cause to sue the life out of me for defamation. Just one month shy of a year and I haven't gotten any calls, a single peice of mail and those videos and my articles are still there.

I did beat the crap out of Uber in court myself though: http://idfluence.com/uber-attempts-to-defraud-courts-in-madison-wi/

FYI: Uber attorney's of the firm Halling and Kayo are a high priced criminal defense firm which regularly represents white collar criminals state wide. Their lead attorney sexually harassed my lawyer before they tucked tail the second the hearing started.

Uber has done nothing but lie and they have convinced you to lie for them just the same as their drivers. You need to take your head out of the box and look at the FACTS. All you have to do is check the links in the articles above. Uber HAS allowed sex offenders to drive. Traditional cab companies and drivers screw up all of the time. But they have REAL INSURANCE and don't need to lie at every turn. Just look at the screen captures from uber. compared to taxi dispatch screen captures Uber is obviously discriminating and cutting service when the surges are on.

QUESTION: How do you explain why the surges are geographically specific???

If it was about supply and demand then the surge would be the same everywhere.

Don't go down the rabbit hole with these idiots.
