(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Neglecting other elements of the cosmological model, the inverse of the Hubble constant, [tex] 1/H_0 [/tex], tells us the time since the Big Bang - the age of the universe. If [tex] H_0 = 70 [/tex]km/sec/Mpc, then how old is the universe?

2. Relevant equations

Given above

3. The attempt at a solution

Apparently the answer is shorter then the time you probably took reading the title...

I think the problem lies in a conversion error. I have converted the constant into km/sec/km, which gives the large answer of [tex] 2.16*10^{21} [/tex] then into m/sec/m, which gives [tex] 2.16*10^{24} [/tex]. this gives an inverse, and thus the age of the universe, to be about [tex]*10^{-24}[/tex]. Where have I gione wrong? as stated above, I am sure its a conversion error, bu can't see where?

Any ideas?
