Discussion Overview

The discussion revolves around the mass composition of the universe, specifically the proportions of dark matter, dark energy, and ordinary matter. Participants explore the breakdown of ordinary matter and raise questions about missing components within that category.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant presents a breakdown of the universe's mass: dark matter (26.8%), dark energy (68.3%), and ordinary matter (4.9%), with further details on ordinary matter composition.
  • Another participant points out a discrepancy, noting that 0.9% is unaccounted for in the ordinary matter breakdown.
  • Some participants suggest that the missing 0.9% could include the mass of planets or dead stars, but there is uncertainty regarding the specifics.
  • A later reply questions the initial breakdown's precision, suggesting that both dead stars and planet mass could be considered ordinary matter.
  • There is a general acknowledgment of imprecision in the original description, but no consensus on the exact contributions of the missing mass.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the exact breakdown of ordinary matter or the nature of the missing 0.9%. Multiple competing views remain regarding what constitutes ordinary matter.

Contextual Notes

The discussion highlights limitations in the initial mass breakdown and the potential for varying interpretations of what constitutes ordinary matter, including the roles of dead stars and planets.

Do i have this right now -- mass of the universe

Edit.

The mass of the universe is divided thus. Dark matter = 26.8%

Dark energy = 68.3

Ordinary matter = 4.9%

The ordinary matter is made up of 3.6% intergalactic gas (nonluminous)

And 0.4% stars etc (luminous)

I hope i have as i am always +-1%

Write correctly please
 
You are missing 0.9% in the ordinary matter breakdown.
 
You are missing 0.9% in the ordinary matter breakdown.

like the planets in our solar system...

Very doubtful. Planet mass is very much smaller than the sun.

The missing 0.9% could be dead stars, but I don't have the specifics.

Oh I just realized the original breakdown description is imprecise...

Dead stars seem like ordinary matter...and so does planet mass...

not worth discussing...
