# General Doppler Shift Equation and the Possibility of Systematic Error in Calculation of Z for High Redshift Type Ia Supernovae

## TL;DR

This paper discusses the general Doppler shift equation and explores how systematic errors in calculating redshift for high-redshift Type Ia supernovae might impact cosmological measurements of the universe's expansion.

## Contribution

It introduces a general Doppler shift equation and examines the potential for systematic errors in redshift calculations affecting cosmological conclusions.

## Key findings

- Systematic errors could significantly alter redshift measurements.
- Potential for misinterpretation of universe acceleration due to calculation errors.
- Highlights need for careful redshift computation in cosmology.

## Abstract

Systematic error in calculation of z for high redshift type Ia supernovae could help explain unexpected luminosity values that indicate an accelerating rate of expansion of the universe.
