I read in a positively curved universe the radial r coordinate ranges from 0 to 1. Is it just a local map?
Why do you suggest that it's a local map? Because the value of r ranges only from 0 to 1? Sounds to me like r is ranging over the full radius of the manifold, and is simply normalized so that r_max = 1. However, without context or more detail, I can't be of any more help.bloby said:I read in a positively curved universe the radial r coordinate ranges from 0 to 1. Is it just a local map?

Mapping a part of the universe by coordinates means that scientists have assigned specific numerical values to different locations in space. These coordinates can be used to pinpoint the location of objects in the universe and create a visual representation of their positions.
This mapping is done using specialized instruments such as telescopes, satellites, and radars. These instruments collect data on the positions of objects in the universe and use mathematical calculations to determine their coordinates.
Mapping the universe by coordinates allows scientists to better understand the structure and organization of the universe. It also helps in identifying and tracking the movement of celestial objects, studying the evolution of the universe, and making predictions about future events.
The accuracy of mapping the universe by coordinates depends on the precision of the instruments used and the complexity of the objects being mapped. With advancements in technology, the accuracy of these mappings has significantly improved over time.
Yes, many organizations and institutions make these coordinates and maps publicly available for educational and research purposes. However, some data may be restricted for privacy or security reasons.
