The world map is changing: The UN has backed replacing the 500-year-old Mercator projection with the accurate Equal Earth projection
(thelemmy.club)
The title falsly implies that mercator is "incorrect". Mercator is an angle preserving projection, meaning all angles are true to real life. The "equal earth" map is an area preserving projection, meaning it retains the true area of countries, but in return the angles are all wrong. This makes equal earth unsuitable for navigation for example.
It is also false to imply that this is some kind of new development. This was very much known all along, mercator simply became the default because world maps used to be primarily for navigation.
