\subsection{more science} \subsection{Age vs lots of things}
\subsubsection{Age vs size}
What has been done: need to find out?
What we'd need:
What we could learn: As galaxies age, mass from the gas gets converted to stars, so we obviously expect stellar mass increases with age, but does the forming of new stars change the size of the galaxy? If we are considering size to be a measure of the range across which we receive stellar light, then how the size changes with age could be a clue about where in the galaxy stars tend to form and/or whether/how orbits of the individual stars change over time.
\subsubsection{Age vs stellar mass}
What has been done: need to find out
What we'd need: stellar mass measurements
What we could learn: It should be obvious that mass will increase with age, but how quickly, and is this rate affected by any other factors (ie morphology, environment?) Would directly measuring the increase in mass over time match the current calculations of star formation rate over time?
