e anceh questo:
more the the galaxy's distance more its redshift mi sembra scorretto, io lo tradurrei così: much bigger is the distance of the galaxy, much bigger is its redshift

in sostanza la feri così pero' é molto tecnica, ci potrebbero essere delle parole che non vanno bene (per esempio "emessa" io userei promulgated), in poche parole non mi assumo responsabilità
![]() The American astronomer Edwin Powell Hubble is famous mainly for the discovery, along Milton Humason, in 1929, of the redshift/distance empiricist law, nowadays universal known as Hubble's law. This law asserts that exist a linear relationship between redshift (the shift to the red of the light spectrum promulgated from celestial body) of the light promulgated by the galaxies and their distance: much bigger is the distance of the galaxy, much bigger is its redshift. Mathematically the Hubble's law can be expressed in: z = H0 D where z is the measured galaxy's redshift, D is its distance and H0 is the constant of Hubble, whose value, today commonly accepted, is approximately 70 km/s for Megaparsec.
