We all live on a spinning ball.  It is not obvious from our normal perspective, travel by land or sea does not appear to move around the circumference of a circle. 

In fact we seem to travel on a flat surface affected only by the contours of the landscape.  Even in the air it is not obvious we are flying around a ball. 

We take the round earth for granted, yet the shape of the earth was not viewed and independently validated until the advent of space travel. 

Flat Earth Society

Even today, in spite of satellite photographic proof the International Flat Earth society promotes the flat earth theory. 

One supporting comment to the theory is the consideration that non experts can be easily fooled by satellite photos.   Experts can understand these photos really depict the earth as flat.

Ancient transcripts show Pythagorus (Greek astronomer and mathematician) had proposed the earth was round based on his observations of the movement of the moons terminator line (the line between the dark and light side of the moon) in 500 B.C.

Subsequent analysis by scientists throughout history continued to provide powerful proofs the world was round.  Arguably after the advent of space photography we obtained visual proof.

My Universe

While I don’t dispute the fact the earth is round, my own interpretation of the spinning ball is that is is revolving around me, not vice-versa. 

This might sound like an odd interpretation of the earths movement relative to my own position, however, in fact for each of us, while we might not state it explicitly, it is inarguable that we are the center of our own universe.
