Hubble's Law Calculator

Calculate the universe’s expansion rate from galaxy velocity and distance.

Calculator

Results

Hubble Constant (H0): 0 km/s/Mpc

Source of Data and Methodology

All calculations are based on the standard formula for Hubble's Law. For further reading, refer to Wikipedia. All calculations strictly adhere to these standard formulas and data.

The Formula Explained

Hubble's Law is given by the formula:

v = H0 × d

Where v is the velocity of the galaxy, H0 is the Hubble constant, and d is the distance to the galaxy.

Glossary of Terms

  • Velocity (v): The speed at which a galaxy is moving away from an observer.
  • Distance (d): The distance from the observer to the galaxy, measured in megaparsecs (Mpc).
  • Hubble Constant (H0): The proportionality constant in Hubble's Law, indicating the rate of expansion of the universe.

How It Works: A Step-by-Step Example

Suppose a galaxy is receding at a velocity of 70,000 km/s and is 1,000 Mpc away. Using Hubble's Law:

H0 = v / d = 70,000 / 1,000 = 70 km/s/Mpc

Frequently Asked Questions (FAQ)

What is Hubble's Law?

Hubble's Law explains the observation that galaxies are moving away from us at speeds proportional to their distance, indicating the expansion of the universe.

How is the Hubble Constant determined?

The Hubble Constant is determined by measuring the velocities and distances of galaxies and applying Hubble's Law to calculate the rate of expansion.

Why is the Hubble Constant important?

The Hubble Constant provides crucial information about the rate of expansion of the universe, which helps in understanding its age and size.
