I've come across a problem recently while trying to get globe earth proponents to snap out of their trance, and come to the realization, as I have, that there is no curvature to the earth. I'll try my best to explain it in a way that even a third grader can understand, because frankly, the site seems to be littered with third graders. No competent adult has argued for the globe as of lately.
You can pull up a Google search engine from laptops, a smartphone, a desktop PC, a Mac, or a tablet, amongst others. When "googling" something, nearly everything you ask, Google, within a second, will give you an accurate answer. You can ask Google, "what is the distance between Japan and Greenland, and in under one second, Google will tell you:
You can, within a click or two, determine the miles, kilometers, or even nautical miles between those locations, and more.
You can even ask Google questions like: what are the dimensions, in inches, of the Washington monument? Within a second, you have your accurate answer:
6,666 inches, and 666 inches wide.
Now to a flat earth scientist, the amount of allowed curvature between two points, IF the earth were a ball is important. Testing to see if that allowed amount of curvature is imperative to test and see if that curvature is there, which is a deciding factor on the shape of the earth. Ergo, if the alleged amount of curvature is not there, then the earth couldn't possibly be a ball that is 25,000 miles in circumference, as modern astronomy claims.
But when asking Google these questions, it won't give me an accurate answer. For instance the question: " how much curvature is there between Hawaii and Los Angeles?" Brings up biased sources, either flat Earth website, or anti- flat Earth websites, none giving an accurate answer to the question in particular.
So, does Google not recognize that there is curvature between Hawaii and California? It appears so. So, until Google recognizes that the earth is or isn't a ball, I'll have to rely on calculating that alleged curvature the old fashioned way.
Pseudoscience: noun; a collection of beliefs or practices mistakenly regarded as being based on scientific method.
Scientific method: noun; a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
The highest form of ignorance is when you reject something you don't know anything about.
