WebAccording to Hubble's law, v = H0 d [ Eq. (17) ], so the time required for every galaxy to have reached its present distance from us would be d / v = 1/ H0 = tH. Thus tH would be the age of the universe if galactic speeds had never been affected by gravity. (It is sometimes called the “Hubble age.”) With H0 given by Eqs. (18) and (19 ), (57) Web5. Hubble's law states that v = H x. Age of the universe is calculated by T = x v = 1 H. but the velocity is not constant; it changes with distance, so I think that this equation cannot be applied because simply the velocity is NOT uniform. v should have been replaced with d x d t, so it gives this differential equation d x d t = H x.

Web15 apr. 2024 · Part III: What Makes Them Real? TLDR: Yes, Hubble images are real. This series of posts is dedicated to the scrutiny of Hubble imagery and a broader discussion of the veracity of astronomical imagery. In this post, we’ll look at a few examples of how Hubble extends beyond human vision to illuminate our understanding of the universe. 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.
