Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their … See more A decade before Hubble made his observations, a number of physicists and mathematicians had established a consistent theory of an expanding universe by using Einstein's field equations of See more Start with the Friedmann equation: where $${\displaystyle H}$$ is the Hubble parameter, See more The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to them by some other method than Hubble's law. This approach forms part of the cosmic distance ladder for measuring … See more • NASA's WMAP - Big Bang Expansion: the Hubble Constant • The Hubble Key Project • The Hubble Diagram Project • Coming to terms with different Hubble Constants (Forbes; 3 May 2024) See more The discovery of the linear relationship between redshift and distance, coupled with a supposed linear relation between recessional velocity and redshift, yields a straightforward mathematical expression for Hubble's law as follows: See more Hubble time The Hubble constant $${\displaystyle H_{0}}$$ has units of inverse time; the Hubble time tH is simply defined as the inverse of the Hubble constant, i.e. This is slightly … See more • Accelerating expansion of the universe • Cosmology • Dark matter • List of scientists whose names are used in physical constants See more WebJul 6, 2024 · It indicates a galaxy moving toward Earth through red shift.
