I don't know the trig approach they use, nor care to spend time on it, but the parallax would be 75x greater for a 3400 mile distance than actual. Two telescopes relatively close together could see this. Only one falsification is needed to debunk their model, but hundreds exist. Finding one element to be correct and hundreds false is not a scientific model, even if one element is found.Helio, in your post #7, I know some flat earth folks. Conspiracy can play a role but for many, flat earth is empirical too. I have studied flat earth videos on measuring the distance to the Moon using telescopes, angles obtained, and plane trigonometry vs. spherical trigonometry. FE folks are correct like the Flat Earth Society. The Moon will always be much closer to the flat disk earth using plane trigonometry. At most the Moon is about 3400 miles away and about 0.5 degrees angular size, so much smaller in size too.
If you remove the teeth from a dog then it won't bite. Redefining objectivity changes things. Objectivity is simply repeating tests by many others and agreeing on the results. And it helps to remember that not agreeing on results for clearly understood reasons, is what scientists look forward to, unlike many philosophies and religions.However, I stand by what I said about QM philosophy interpretation of nature. Applying to the macro universe leads to no objective reality and the space.com report does suggest this to me.
I like the idea of letting them build their own rockets instead like Mike Hughes did:Probably the best way to debate a flat-Earther would be to send one up to the ISS and let them tell you what they see with their own eyes.
Our earth is both flat and curving like boat to swim in the spaceI have a simple one. I live in Los Angeles, in 2015 I had a trip to Japan, then India, Italy, New York and finally back to Los Angeles. I bough a small portable GPS, I personally test it going from Beverly Hills to Santa Monica the GPS signed going West. On my first trip to Japan (from LA) I went West the whole time. On the second trip to India and Italy again always West. From Italy to New York again West, and finally back to Los Angeles always going West. If the Earth was flat, how did I travel ONLY WEST and went back home??? The GPS records the trips you do, so I can send the trip I did to anybody.
I have found that if you ask them a question involving geometry, such as what is the distance, on a east west course, between Brisbane, Australia and Santiago, Chile, they will usually run away.
Does QM imply as in your cat example that ALL available outcomes are to exist as options. I'm not sure if its even an applicable point, but I can count using cardinal numbers from 1 to infinity or I can count from 1000 to infinity. In both case I have the potential to go to infinity but in the latter 1-999 never existed.LijeBaley, I point out the *quantum voodoo* as a philosophy of interpreting nature, seems to appear more and more in QM reports. If I apply this approach to the macro universe, the cat is dead or alive also leads to the earth is flat and round too. Your version of reality is yours, flat earth folks will have another version of reality and no one can define a standard of verification that works for all to accept it seems. In my opinion, the scientific method breaks down and replaced with a different definition of reality, based upon different views and needs. I see this as the direction that science is taking today - my opinion. I do not agree with this but it looks like that to me---Rod
I actually think there could be a way to use a flat earth class practically at a school. It doesnt have to be about anything being real or not, classes use fiction and fact both often. For many of these FEs its the most they have ever studied science and enjoyed doing it to boot. Surely not for everyone, but there would be plenty to learn about real science using this like a detective game. Not everyone likes to learn the former way and in the long run you may just discover something regardless. Many great discoveries are by accident in some ways so think of the new chances looking into new ideas, whatever it may be. EDIT ADD: ex. An alternate idea for a sun could be more like a "fiber optic" one where you can use a model of a water light pipe and focus on total internal reflection-perhaps set it up as a relay to make it appear to go full circle. Many genuine concepts there to work with. Throw them another loop even with a new VEST idea Vortex Earth Street Theory where it is more about fluid mechanics.LijeBaley, consider the space.com report on QM universe I cited in post #2 where apparently there is no objective reality. Your proposed evidence for the flat earther to see, assumes that there exist in nature an objective reality that can be clearly defined. Yet space.com report undermines such a concept in science. Applying QM universe rules to the ISS and view from the ISS, that suggest the ISS may not be real and what is seen below may not be real too. A flat earther could simply cite this now and ask that the flat earth be taught in sciences classes now in public schools as an example. Also the Sun could be moving above the flat disk earth too, a form of geocentric astronomy that can be valid because there is no objective reality now in science, apparently.
Some folks' opinions will never be swayed, regardless of the facts before them.
Yes, but some are which is what makes it useful to argue facts, besides that it is hard to distinguish what people know or believe from discussions. That people can be swayed by facts is of course not only shown by the existence of science, but by the fact that years of education and science correlates with less conspiracy and other superstitious views.Your time and efforts are better spent elsewhere.
I have trouble reading this, but I think that it is better to observe that Earth appears locally flat but is a ball on the scale of Earth. C.f. how you can trick an insect to run around a branch by turning it over, it appears as a flat surface for it.Our earth is both flat and curving like boat to swim in the space
Snell's law of refraction describes that happen when light passes between two different isotropic media [ https://en.wikipedia.org/wiki/Snell's_law ]. You can see it in a drinking glass by standing a spoon in it.Is there a way to prove that the ISS photos and other of earth are NOT a Snell Window view?
yes, I am aware of how it works, and it isn't isolated to the mediums of a water-air boundary. Not too much about superfluids I see available online w/Snell's law in mind, mostly in line w/ these kind of studies. https://arxiv.org/pdf/1811.02110.pdf Perhaps if they ever test out those LEO debris programs like SpaDE and other surface air cannons in higher orbit somehow... excitation of superfluids having their critical velocity manipulated by vortex rings has had many studies. Certainly it would need the distance of deeper space where the -2K temp of space is also close to the same temp as the lambda point of liquid Helium to act as a superfluid. Seeing as many FE tend to make up wild hypothesis' though, they may just claim a new concept like "matter-time" that would allow the superfluid effect closer either way or within some kind of meniscus boundary. I think most of their raw data is from Youtube not journals though.We have no statistics saying that it works with tackling conspiracy theory in an isolated discussion as a trust building exercise. And it is demeaning. I'll rather laugh at them, so the demeaning is happening on the side of the social offender.

All windows are "Snell" windows in that sense, but since they are planar the effect appears as a linear translation up close - easily seen in double window shadows. Astronaut images are taken under such conditions.
The Snell window of an optical cone delimited by total internal reflection only happens - as every swimming kid knows - if you have a situation of a highly refractive index material such as water and starts out at depth distances of meters. "At a depth of 10 feet, you will probably be a little too deep for a perfect window, but slowly ascend and keep looking up. Between three and six feet, the entire surface, from horizon to horizon, will be clearly visible!" It is a groovy feeling to jump from a high trampoline, stay deep while the bubbles dilute, and look up at the optical effect.
There is no swimming pool on ISS.
