Hubble's law is considered the first observational basis for the expansion of the universe, and today it serves as one of the pieces of evidence most often cited in support of the Big Bang model. The motion of astronomical objects due solely to this expansion is known as the Hubble flow. Meer weergeven 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 … Meer weergeven 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 general relativity. Applying the most general principles Meer weergeven Start with the Friedmann equation: where $${\displaystyle H}$$ is the Hubble parameter, Meer weergeven The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to … Meer weergeven 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: Meer weergeven 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 … Meer weergeven • Accelerating expansion of the universe • Cosmology • Dark matter • List of scientists whose names are used in physical constants Meer weergeven Web28 aug. 2024 · Since H 0 ≃ 70 km/s per Mpc, and v P ∼ 1000 km/s, then a quick bit of …
