I am new to the forum. After reading some of the arguments postulated on many threads, I became inquisitive but remain quite skeptical. Ultimately, my skepticism arises from one question... on what basis does one make the claim that the Earth is flat?
I am a physicist as well as an aerospace engineer. I am employed with NASA where I work on many projects including the Ares launch vehicles. I have always based my beliefs on science and reason. Throughout my experiences and my research, I have never come upon any circumstance that has caused me to question the Earth's spherical shape. But I am an open-minded individual and I ask this question in order to gain a better understanding of a topic that I find curious.
