# Increased Expansion Rate

 P: 1 Hello all... Hope you'll allow a complete novice to sneak in for a moment or two with a couple of questions: (1)Disregarding any preferential viewpoint, like Earth, and at any instant, is universal expansion velocity the same? (2)In what way(s) does the recently discovered increased universal expansion rate affect the Hubble Constant value. (3)What is the value of the above increased expansion rate? Easy enough questions I'm sure, but the hard part is putting any answers into simple language that an idiot like me can understand
 Sci Advisor PF Gold P: 9,090 1] there is no preferential point. 2] the hubble constant is constant 3] the universe is expanding Welcome to PF, porquat! Good questions. There are many studies that affirm what I claimed. And there are other studies that attempt to refute those claims. You have the freedom of choice to take sides.
Considering that $\ddot a / a = - H^2 q$, with q = -0.6 (current deceleration parameter) and H = 71 Km / s per Mpc (current Hubble parameter) you get about 4.3 × 10-35 s-2. This is about 1.3 × 10-15 km / s2 per Mpc. (1 Mpc = 326 million lightyears).
