I've been doing some Cosmology, but I'm having a really hard time understanding the results for the age of the Universe intuitively. For example I can work out from the FRW equation that in the case of no Cosmological constant and no radiation in a flat matter dominated universe the age is approximately:(adsbygoogle = window.adsbygoogle || []).push({});

\begin{equation}

t_{0} = \frac{2}{3H_{0}}

\end{equation}

And in the case of no cosmological constant, no radiation, no matter and only curvature:

\begin{equation}

t_{0} = \frac{1}{H_{0}}

\end{equation}

However I don't understand the results physically. Are there any good ways about thinking about these parameters and their effects on the age of the Universe today?
