**Formula:**`Flux = Φ / A`

## Introduction to Flux in Cosmology

In cosmology, flux is a measure of the flow of energy or particles through a given surface. The formula for flux, Φ, calculates the amount of energy or particles passing through a given area, A.

## Parameter usage:

`flux`

= flux measured in watts per square meter or particles per unit area`area`

= area of the surface through which the flux is measured

## Example valid values:

`flux`

= 8 (watts per square meter)`area`

= 4 (square meters)

## Output:

`flux`

= calculated flux value

## Data validation

The flux and area should be greater than zero.

## Summary

This formula is crucial in cosmology for understanding and analyzing the energy and particle flow through specific areas in the universe.
