Hi, i am confused and perhaps someone can help me:(haha i am so confused i need someone with atleast a phd or doctorate in physics ) v/d=H0 v= velocity of distant galaxy H0= hubbles constant d=distance to galaxy The problem i having is that if since the expansion of the universe is at present accelerating, the value of the Hubble constant is presently increasing, the Hubble constant must/has always been decreasing because the universe is getting older and 1/H0 = age of universe can someone tell me whether the hubbles constant is increasing or decreasing, and why. At the big bang is hubbles constant very small, or very large? Is density proportional to the hubbles constant? or what is the link between them, i guess that at big bang density is very large, which means very large gravational forces, rate of expansion is therefore slow, then as the universe expands and spreads out, expansion gets faster(density smaller) H0 is therefore bigger as time goes on, this is another contradiction to the earlier piont about, 1/H0 = age, Is the Hubbles constant the exact same as the rate of expansion? If the rate of expansion was constant, then as time goes by galaxies move further away and from hubbles law are moving faster and faster, so the rate of expansion is not constant its getting faster? someone explain please, you can see how confused i am. Any help is appreciated! Thank you!
