This calculator helps you determine the expansion rate of the universe using Hubble's Law. It's designed for astrophysics students, researchers, and enthusiasts who need a precise and reliable tool.
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.
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.
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
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.
The Hubble Constant is determined by measuring the velocities and distances of galaxies and applying Hubble's Law to calculate the rate of expansion.
The Hubble Constant provides crucial information about the rate of expansion of the universe, which helps in understanding its age and size.
