Web8. nov 2024 · Luminosity distance and redshift are two things we can measure. The relationship depends on a ( t) and the curvature k. In principle, if we measure distances and redshifts for objects at a variety of distances we could then infer a ( t) and k. The general relationship between redshift and luminosity distance is contained in these equations: Web7. dec 2024 · Redshift is a phenomenon that occurs with waves of electromagnetic radiation when they demonstrate the Doppler effect by their source moving away from an observer. … date not showing up in pivot table https://myshadalin.com
