Introduction

Eclipses can't work on a flat earth. A constellation is just a line of sight effect, just the stars appearing in some random pattern that we give a name to. The star with the greatest proper motion across the sky is a barnard star. You can measure the distance to the nearest stars using a technique called parallax. If you take a base line of the earth in january and july, half the orbit of the earth, you will see that red star jumps back round again. When astronomers saw a supernova in 54 lantic they looked at it through good telescopes because it's so far away. It's not some dome with lights on an alien planet.
