I think the best evidence is when he healed the blind man twice in Mark. After the man could see he had visual agnosia and needed that also fixed. So why would the authors put that in unless it really happened? If they made it up then to make Jesus appear more divine they wouldn't want to or medically know to record two healings.
The Pfizer vials in the US have a six character lot number like EK5730. There's no way thousands of nurses are going to know how to decode that and give saline to the "important" people. Some lot numbers certainly do seem more deadly than other lots though as reported on Stew Peters and by others. So maybe it's random, or intentional or maybe just poor quality control with zero liability for throwing any concoction of crap together.
The best way to do it would probably be to use a fixed lens and use C spacers to make the focal length short enough to image a calibration pattern. A 3" pattern is about $600 and is accurate to less than a micron. Then once the lens is calibrated remove the spacers so you can image the curve. You can't use a zoom lens because changing the zoom changes the error mapping of the lens.
Like you said a high altitude is better because more curve increases your measurement to error ratio. Anyway there's only a handful of people who know how to do all that but someone could probably research it and figure it out using something like OpenCV.
Also, after all that some model for atmosphere refraction should also be considered.
So in the end you cannot just look with your eyes and think something is flat. Imagine printing out 10 lines on paper and one has a 1% curve. You could never see the difference.
Ok, let's start with the first one "1) The horizon always appears perfectly flat 360 degrees around the observer regardless of altitude."
According to the "spinning ball" theory if you are 6 feet tall you can see at most about 35,000 feet in any direction over water. That's an angle of curve about 0.01 degrees or about 0.02%. A good lens has a distortion about 0.50%. Thus the lens has 25 times more error than what he is claiming he measured.
Now you can calibrate with some sort of photo target. That's not an easy task. You need a good target, software and with a 12MP camera you are at about 8 feet per pixel. So to see curve you need to need to calibrate out the 15 pixel error (0.5% of 3000) and measure the 1 pixel curve. Or you could possibly find a low distortion lens. One that good would cost six figures.
I am going to say that the yoga instructor who made this claim has probably not done these things. So there is no evidence for his first presumably most important claim. Thus, there is little reason to look at the other 199.
If the big bang was exactly as described then everything would be expanding in predictable directions at predictable rates. That's not happening so they claim "dark matter" which is just another way of saying "we don't really know this entire thing could be some wacky simulation."
Go on digikey and look up some random auto chips. First one I tried was PIC16C54C-04I/P. Lead time 30 weeks. Two years ago the lead times for nearly everything was 2 weeks or less.
