Hubble's law says that
Web26 dec. 2003 · The slope of the line in the Hubble diagram is called the Hubble constant (H o ), directly related to the age of the universe: Hubble's Law says that velocity = H o × distance and, because time = distance/velocity, there is a natural Hubble time, to, associated with the Hubble expansion, to = distance/velocity = distance/ (H o × distance) … WebThe NGC 55 galaxy is at two megaparsecs, so we now need to multiply the parsec distance per the parsec to NGC 55. NGC 55 (distance) = 2 ⋅ 10 6 ⋅ ( 3.086 ⋅ 10 16) = 6.17 ⋅ 10 22 m. Now, we can substitute this information into Hubble’s law equation and obtain the galaxy’s velocity. However, we must first convert the Hubble constant to ...

The improved Hubble constant value 45.5 miles per second per megaparsec. (A megaparsec equals 3.26 million light-years.) The new value means the distance between cosmic objects will double in another 9.8 billion years.
Web29 okt. 2024 · The Hubble–Lemaître law describes the effect by which objects in an expanding Universe move away from each other with a velocity proportionally related to their distance. This resolution was proposed in order to pay tribute to both Lemaître and Hubble for their fundamental contributions to the development of modern cosmology.
