Discussion Overview
The discussion revolves around the unit transformation of the cosmological constant, specifically converting values between GeV and eV, as well as comparing energy densities in different units. The scope includes theoretical aspects of cosmology and mathematical reasoning related to unit conversions.
Discussion Character
- Technical explanation
- Mathematical reasoning
- Debate/contested
Main Points Raised
- The original poster seeks clarification on how to convert the cosmological constant from GeV4 to eV and vice versa, as well as comparing energy densities.
- One participant suggests that the conversions are useful for cosmology equations, providing specific conversion factors for temperature, mass, time, and length related to GeV.
- Another participant points out that eV is a unit of energy, while energy densities have dimensions of energy/length3, which can be related to energy4 under certain unit conventions.
- The original poster expresses gratitude for the explanation and invites further contributions from others.
Areas of Agreement / Disagreement
Participants generally agree on the need for unit conversions in cosmology, but there is no consensus on the specific methods or implications of these transformations, particularly regarding the comparison of energy and energy density.
Contextual Notes
The discussion includes assumptions about unit conventions, such as setting c=hbar=1, which may not be universally accepted. There are also unresolved aspects regarding the implications of these conversions for cosmological models.
