It's been a while since I last used Latex, so please bear with me.
As the title reads, I'd like to have two signature side by side (50% each) at the bottom of a medical report. This is what I currently have (apparently with slightly changed author names):
\flushleft
\newlength\jm
\settowidth{\jm}{Luke Skywalker}
\begin{tabular}{p{\jm}}\hline
\centering\footnotesize (Luke Skywalker)
\end{tabular}
\vspace{10 mm}
The force is strong in my family
\vspace{5 mm}
\flushleft
\newlength\mb
\settowidth{\mb}{Darth Vader}
\begin{tabular}{p{\mb}}\hline
\centering\footnotesize (Darth Vader)
\end{tabular}
And it looks like this in scrartcl:

How can Luke stand right next to his father (Luke left, both with underlines) ?
