View source for List of questions flerfs cannot answer


This is a list of questions that flerfs refuse to answer, don't know the answer to, or don't give consistent answers for.

==Astronomy==

===Basic geometry===
* Why is there a south celestial pole?
** Why are there circumpolar stars in the Southern hemisphere?
** Where is the south celestial pole located 'on' the [[firmament]]?
* Why is Polaris not visible in the Southern Hemisphere?
* Why is Sigma Octantis not visible in the Northern Hemisphere?

===Eclipses===

====Lunar eclipse====
* What is a lunar eclipse?
* Why is the shadow on the Moon always a circular arc?

====Solar eclipse====
* How do we predict the path of totality?

===Sun===
* Why does everyone see the same sunspots?
* Why does the Sun not change in angular size?
* Why does the Sun set?
* How do we predict what time the Sun will set?
* How do we predict what time the Sun will rise?
* Why does the sun set right-to-left in the Southern Hemisphere, and left-to-right in the Northern Hemisphere?

===Moon===
* What causes Moon phases?
* What are lunar craters?
* What is the Moon made of?
* What causes {{wp|libration}}?
* Why is the Moon's angular size consistent with an elliptical orbit?
* Why does everyone see the same side of the Moon?

===Stars===
* What are stars?
* How far away are stars?
* What are stars made of?
* What causes {{wp|stellar parallax}}?
* What causes {{wp|stellar aberration}}?

====Retrograde motion====
* What causes retrograde motion?
* Why does the heliocentroc model perfectly predict retrograde motion?

===Planets===
* How did {{wp|Ole Romer}} successfully measure the speed of light by timing occultations of {{wp|Io}} throughout the year? 
* Why is there a complete lack of perspective effects due to the planets being 'local'?
** Why does everyone see Saturn's rings at the same angle?
** Why does everyone see Jupiter's Great Red Spot in the same position?
** Why does everyone see Jupiter and Saturn's moons in the same positions?
** Why does everyone see Mercury and Venus' phases at the same angle?

====Inferior planets====
* Why do {{wp|Mercury}} and {{wp|Venus}} show phases?
* How does the heliocentric model perfectly predict the phases of Mercury and Venus if its 'incorrect'?

===Firmament===
* How high is the firmament?
* What is the firmament made of?
* What is beyond the firmament?

===Astronomy equipment===

====Equatorial mounts====
* How do [[equatorial mount]]s work?
* How do you polar align an equatorial mount in the Southern Hemisphere?
* How do equatorial mounts prevent field rotation?

====Planisphere====
* Why is there no working {{wp|planisphere}} of the entire sky?
* Why do planispheres show stars below the ground?

===Software===
* How do {{wp|GoTo telescope}} mounts know where to point?

====Stellarium====
* How does Stellarium make accurate predictions, considering it uses an 'incorrect' model of the solar system?

==Geodesy and cartography==
* What is the map of flat Earth?
** Does this map have an accurate scale?
** Where are the north and south poles?
** Is this map compatible with observations of the celestial sphere?

==Horizon==
* Why is there a sharply defined horizon?
* How can the horizon obstruct distant objects?

==Navigation==

===Celestial navigation===

===Aviation===
* Why is the globe the only model of Earth that can consistently and accurately predict flight times?

====Southern Hemisphere flights====
* How is a direct flight from Sydney to Santiago possible?
** How should we plan this flight using flat Earth?
** What is the flat Earth prediction for this flight's flight time?
