Hubble's constant/length?

  1. Apr 15, 2008 #1
    Ok I'm kinda confused of what is the relationship between hubble's constant, hubble's horizon length and how all those calculation works. I'm reading a textbook called quarks, leptons and the big bang but they don't explain it clearly, maybe I'm just slow but could anyone explain to me thnx!

    Hubble constant is 70 km/s / Mpc.

    Take the speed of light divided by 70 km/s and multiply by 1 Mpc.

    hmmm ok maybe I wasn't clear of what I was trying to ask. I want to know how it relates to the inflation of the universe and the how the horizon is being affected during this major expansion. I don't want any calculation I just want to know the concept, but thanks for the hubble constant calculation!
