Hubble's Law

Introduction to Hubble's Law

Hubble's law describes the expansion of the universe. It states that the velocity of a receding galaxy is directly proportional to its distance from the observer. In this formula, v is the velocity of the galaxy, H0 (Hubble constant) is the constant of proportionality, and D is the distance of the galaxy from the observer.

Parameter usage:

• velocity = velocity of the galaxy
• distance = distance of the galaxy from the observer

Output:

• v = velocity of the galaxy

Data validation

The velocity and distance should be greater than zero.

Summary

This formula helps in understanding the movements of celestial objects and the expansion of the universe.
