The hubble law
WebSep 2, 2024 · Hubble's law describes a uniformly expanding flat universe. Hubble's law says: the furthest object recedes faster than the nearest one. Hubble's law doesn`t explain why distant objects... 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. See more 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 … 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 field equations of general relativity. Applying the most general principles to … See more Hubble time The Hubble constant $${\displaystyle H_{0}}$$ has units of inverse time; the Hubble time tH is … 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. … 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 … See more Start with the Friedmann equation: $${\displaystyle H^{2}\equiv \left({\frac {\dot {a}}{a}}\right)^{2}={\frac {8\pi G}{3}}\rho -{\frac {kc^{2}}{a^{2}}}+{\frac {\Lambda c^{2}}{3}},}$$ where $${\displaystyle H}$$ is the Hubble parameter, See more • Accelerating expansion of the universe • Cosmology • Dark matter • List of scientists whose names are used in physical constants See more
