Redshift

6 reports
Redshift is an astronomical phenomenon recognized by characteristic signals, timescales, energy scales, and source environments. Evidence comes from source environment, physical mechanism, and energy scale, and competing models remain viable when observations are sparse or indirect.

The key evidence surrounding Redshift comes from source populations, while also considering competing physical models and source environment. The discussion asks what can be established from population statistics about competing physical models and whether a compatible result appears in independent detections; the comparison must account for the fact that selection effects and uncertain source distances can alter inferred rates or energies.
