  • who is to say, that, all stars are not in motion? parallax would be more useful measuring the flatness of the earth

  • Why in all books and vids I looked to find a good explanation the star is always perpendicular to the plan make by the Sun and the Earth and in my fucking exam was not ?? why that fucking star made an angle with the normal axis ??? so what about a star who makes an angle with the normal axis, and for final case what happens if the angle is 90° ?
