Scientific Foundation of Hubble’s Law
Hubble’s Law, formulated by Edwin Hubble in the 1920s, states that the recession velocity of a galaxy is proportional to its distance from Earth. The formula, v = H₀ × d, uses the Hubble constant (H₀), which is approximately 70 km/s/Mpc based on modern measurements from the Planck satellite and other observations. This constant represents the current rate of expansion of the universe. The Hubble's Law Calculator uses this value to ensure calculations align with peer-reviewed scientific data, providing trustworthy results for users.
Applications in Cosmology
The Hubble's Law Calculator has wide-ranging applications in cosmology. By calculating recession velocities, users can estimate the rate of cosmic expansion, study galaxy clusters, and explore the universe’s large-scale structure. It also aids in understanding redshift, a phenomenon where light from distant galaxies shifts to longer wavelengths due to their motion away from Earth. This tool is invaluable for visualizing how galaxies recede, supporting studies of the universe’s history and future evolution.
Benefits of Using the Calculator
The Hubble's Law Calculator offers several benefits:
- Accuracy: Based on the verified Hubble constant, ensuring reliable results.
