Every night, for several months now, I have gone outside at a specific time (10pm) and observed a specific constellation in the sky. This constellation, relative to my position as an observer, is always in the same position in the sky.
At 10pm every night, no matter what time of year it is in Australia, Summer, Winter, Spring or Autumn, it will be dark, or near dark - enough to observe the sky and stars.
I only became interested in doing this after watching a doco on the flat earth model. I'm not sure I believe it, but it is becoming more relevant to me.
If the constellation I observe is due west of my position at 10pm every night, then in 6 months time, the earth is supposed to be on the other side of the sun, and it is still dark, meaning - if the sun is the center of our known universe, my observation at 10pm will be when my position on the earth is facing away from the sun, today, and in 6 months time from today. In order to see the same constellation at the same time and in the same position - I would not only be needing to look through the earth, but also see it through the sun on the other side of the earth.
How is it possible for me to see the same constellation in the same position, from the same exact time of night, facing the same direction at now and 6 months time from now if the earth is orbiting the sun?
