Where Can I Find a Paper on Dark Matter Density Percentages in the Universe?

Click For Summary

Discussion Overview

The discussion centers on finding academic papers or resources that detail the percentages of visible matter, dark matter, and dark energy in the universe. It involves references to existing literature and educational materials related to cosmology.

Discussion Character

  • Exploratory, Homework-related

Main Points Raised

  • One participant requests papers that provide specific percentages of visible matter, dark matter, and dark energy in the universe.
  • Another participant suggests that papers from the WMAP science team would be relevant and mentions that an introductory cosmology textbook might be a better resource.
  • A third participant provides a link to a Wikipedia page as a good description of the topic, including the requested information.
  • Another participant points out that the numbers can be found in the Lambda-CDM model Wikipedia page and clarifies that "baryonic" refers to normal matter.
  • A final participant expresses gratitude for the information received.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of Wikipedia as a resource, but there is no consensus on a single academic paper or source that definitively provides the requested percentages.

Contextual Notes

Some participants reference Wikipedia, which may have limitations in terms of academic rigor compared to peer-reviewed papers. The discussion does not resolve which specific papers are most authoritative.

Hi...

Wikipedia says that only five percent of the universe is matter that we know... Can anyone tell me a paper where the percentages of visible matter, dark matter and dark energy in the universe are given?

Any of the papers from the WMAP science team will discuss this. However, an introductory cosmology textbook is probably a better place to go.
 
Thanks...got it! :smile:
