What Is the Logarithmic Map of the Universe?

Click For Summary

Discussion Overview

The discussion revolves around the concept of a logarithmic map of the universe, particularly in relation to Earth. Participants explore the implications of such a map and seek clarification on specific astronomical terms and units used in the context of the map.

Discussion Character

  • Exploratory, Conceptual clarification

Main Points Raised

  • Some participants find the logarithmic map of the universe intriguing and share links for further exploration.
  • One participant suggests that the map should be described as relative to Earth.
  • A participant inquires about the meaning of "parsecs" and the units represented on the horizontal axis of the map, questioning whether they represent time.
  • Another participant provides a definition of a parsec and speculates that the horizontal axis may represent divisions of the Earth's circumference into hours.

Areas of Agreement / Disagreement

The discussion includes questions and clarifications but does not reach a consensus on the interpretation of the map or the units used.

Contextual Notes

There are unresolved questions regarding the specific units on the horizontal axis and the implications of describing the map relative to Earth.

Very interesting

*bookmarks it*
 
more accurate to say is a logarithmic map of the universe relative to earth.

btw: 1.what does parsecs stand for?
2. what units does the horizontal axis stand for? (time?).

A parsec is a commonly used unit of distance in astronomy:

It doesn't say what the units at he bottom are but it looks like they've divided the Earth's circumfenrce into 24 hours. (i.e. 24 hours = 360 degrees).
