age of universe Thankyou for your help but what you gave me is a bit over my head. "I have been given the task the Hubble constant is thought to be in the range 10 - 20 km/sec ^-1. What age range does this imply for the universe?" I am not sure where to begin...

Please can somebody explain how the age of the universe can be determined using Hubbles Constant? If the constant is taken as 10km/s (just for the sake of easiness), how can this be figured out using calculations? I appreciate any help!

i study at the university of abertay dundee and travel from edinburgh. My coursework is from "horizons of science 1". this module is concerned with the big bang, black holes, telecommunications and cosmological phenomena

re thankyou very much jess! I need the help for some uni coursework. p.s. I am from edinburgh too!

d is in km and theta is in degrees. This is as close as i can get: for this answer i get a result of: 343774677078406.6587981892079753 So, is this answer the number of km? what is this answer in exponential form? ie: 34 * 10tothepower13? 1 light year is 9.467*10tothepower12, so...

hi there thankyou for your interest in my posting jess d is in km theta is in degrees

please can somebody help me with this parallax equation: D=distance to star theta=angle using the rule D=(d/2)/tan(theta/2) when d = 300*10tothe6 and theta = 5*10tothe-5 what is the distance to the star in km and light years?
