WebHubble found a linear relationship between distance and redshift v = cz = H o d where Ho is a constant of proportionality, now called the Hubble Constant . Hubble's finding implies that the more distant a galaxy, the larger the recession velocity. This leads directly to the expansion of the universe, which we will discuss in some detail. http://astro.wku.edu/astr106/Hubble_intro.html

"Webbiguities about the Hubble law [1] have long been pointed by Harrison [2], such as the common confusion between the redshift-distance and velocity-distance relationships. It would also be preferable to know what we measure ex-actly. What is the distance perceived, using parameters such as luminosity and magnitude, through a telescope?

It was proof that the Universe is expanding. It was also the first observational support for a new theory on the origin of the Universe proposed by Georges Lemaitre: the Big Bang. After all, an expanding Universe must once have been smaller.

WebApr 19, 2024 · 19. Yes, definitely. The Hubble constant describes the expansion rate of the Universe, and the expansion may, in turn, may be decelerated by "regular" matter/energy, and accelerated by dark energy.
