Discussion Overview
The discussion revolves around the interpretation of the notation h703 in the context of supernova rates, specifically in units of SN rate per year per Mpc3. Participants seek clarification on the meaning and implications of this notation.
Discussion Character
- Conceptual clarification, Technical explanation
Main Points Raised
- One participant asks for clarification on the meaning of h703 in supernova rate units.
- Another participant explains that h70 is a dimensionless number related to the current rate of expansion, defined as the current Hubble rate divided by 70 km/s/Mpc.
- A follow-up question is posed regarding the significance of the exponent 3 in this context.
- Another participant comments that a dimension can be viewed as another reference frame.
Areas of Agreement / Disagreement
The discussion includes some agreement on the definition of h70 as a dimensionless number, but the significance of the exponent 3 and the implications of dimensions remain less clear, indicating unresolved aspects of the topic.
Contextual Notes
Participants have not fully explored the implications of the exponent 3 in relation to the units, nor have they clarified how dimensions relate to reference frames in this specific context.
