The aim is to test an alternative model explaining the curvature in the Hubble diagram of type Ia supernovae observations without relying on dark energy.
Overlay predicted distances from consecutively-expanding particles with ΛCDM predictions on the Pantheon+ SNe Ia Hubble diagram.
Analyze the curvature of the Hubble diagram over a specified redshift range.
The proposed model accurately tracks the observed curvature of the Pantheon+ SNe Ia Hubble diagram.
Distant SNe Ia are found to be further away than expected under the traditional dark energy hypothesis, suggesting a different explanation.
