Hubbles lag beskriver observationen inom fysikalisk kosmologi att hastigheten med vilken olika galaxer avlägsnar sig bort från oss är proportionell mot deras avstånd från jorden. "Lagen" är en teori från 1929 uppkallad efter astronomen Edwin Hubble från USA. Då han hade märkt att galaxerna rör sig från varandra, slöt han sig till att universum expanderar. I själva verket expanderar rum-tid volymen av det observerbara universumet och Hubbles lag är direkta fysiska observationer av d…
Initially proposed hubble’s law
Did you know?
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. Visa mer 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 … Visa mer 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, Visa mer The value of the Hubble constant is estimated by measuring the redshift of distant galaxies and then determining the distances to them … Visa mer • Accelerating expansion of the universe • Cosmology • Dark matter • List of scientists whose names are used in physical constants Visa mer A decade before Hubble made his observations, a number of physicists and mathematicians had established a consistent theory of an expanding universe by using Visa mer 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: Visa mer 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 … Visa mer Webbför 45 minuter sedan · Finally, it should be noted that JUICE’s plans may be revised based on the latest results from NASA’s Juno mission.

WebbThis legacy reflects the work of the telescope’s namesake, renowned 20th century astronomer Edwin Powell Hubble. Like the Hubble Space Telescope, Edwin Hubble’s discoveries transformed the frontier of scientific knowledge. His work took us beyond the Milky Way and placed us in an ever-expanding universe with a myriad of galaxies … Webbexperiment is proposed as a metaphor for describing one of the most intriguing facts of cosmological theories, i.e. the Hubble law of space-time expansion. In this metaphor, the Universe is described as an inflating balloon that has on its surface dots representing galaxies in recessional motion.
