Ushuaia 55°S. Cape Town 33°S. Hobart 55°S.
Ushuaia current local time. 05.45.
Cape Town current time 10.45.
Hobart current time 18.45.
On 21st December all these places will have daylight at the same time. Sunset in Hobart is 20.48, it's 11 hours ahead of Ushuaia. So for approximately 4 hour hours they're all simultaneously having sunlight.
Now, on a spherical globe that works.
On the flat/circle shaped one they're all over the place. How can the sun effectively shine for longer on the southern most tips of 3 continents across a range of about 15,000 miles (probably even greater distance in discworld), but keep more northern places darker.
Why does it get darker earlier the further north you go? Hobart and Ushuaia at 55°S get a longer day than Cape Town at 33°S for example. But hold on
.. 6 months later the further north you are the longer the days.
How does the reflection change its lightning up times, and centralize its light in May/June/July, but then ignore the centre in December and aim only at the circumference?
It's crazy stuff
