Every day he would chart the ship’s location, speed, heading, etc so he could make a map of their path. Ultimately, he realised that the path the ship was taking would be impossible if the earth was flat.” Zen Garcia (2016). Firmament: Vaulted Dome of the Earth. Lulu.com ( self-publishing platform).

As SB Nation breaks it down, the point guard declared the Earth flat on a podcast in February, and then returned to the same podcast in March to say he was just trying to start a conversation. In September, he was asked by CBS Boston what he really believed and said his original statements were just an "exploration tactic" and that people should do their own research. In October, he again floated the notion that the question of whether Earth is round is up for debate, saying he didn't know whether pictures of Earth from space were real. 4.

The Boston Globe.Looking at my photos, it’s easy to imagine being an incredibly small creature living on the surface of the basketball,” Jeff told Bored Panda. “From the perspective of that tiny creature, the “horizon” of the basketball would always look “flat”. Using the appearance of the horizon as primary evidence, this creature would likely assume that they are living on a flat surface. I don’t expect this to change the minds of any entrenched flat earth believers, but I hope that this interesting experiment could help someone that may be susceptible to persuasion by the flat earthers’ arguments.” However, a 36-year-old software engineer called Jeff went for something much simpler. He used a basketball and a macro lens to simulate the curvature of the Earth and took photos to calculate the equivalent. Quite brilliant, isn’t it? The meme itself is quite old, having been posted to Reddit’s r/dankmemes seven months ago, but it didn’t get a huge amount of attention at the time.
