Discussion Overview
The discussion explores the hypothesis that dark matter could consist of trans-Seaborg elements, which are theorized to exist beyond atomic number 126. Participants examine the implications of this idea in relation to the properties of dark matter, particularly its detection and interaction characteristics.
Discussion Character
Main Points Raised
- One participant questions whether dark matter could be composed of trans-Seaborg elements, referencing Seaborg's hypothesis of an "island of stability" for these elements.
- Another participant argues that dark matter cannot consist of these elements because they are baryonic matter, which would interact with electromagnetic fields and emit radiation, unlike dark matter.
- A further contribution highlights the baryon to photon ratio from big bang nucleosynthesis, suggesting that the amount of baryonic matter is insufficient to account for the observed dark matter, reinforcing the argument against super heavy elements as dark matter.
Areas of Agreement / Disagreement
Participants express disagreement regarding the possibility of trans-Seaborg elements being dark matter, with some asserting that they cannot be due to their baryonic nature and the implications of cosmological constraints.
Contextual Notes
The discussion does not resolve the broader implications of dark matter's composition or the nature of trans-Seaborg elements, leaving open questions about definitions and the stability of such elements.
