In this case I believe the autotune to be the best possible route. Who better to wax lyrically about the wonders of science than Carl Sagan, Neil deGrasse Tyson, Richard Feynman and their ilk?
Especially Sagan, beautiful voice and manner. The best person to transport science to the public imo.
Feynman is a super-galactic legend aswell. A legend who i discovered through the symphony of science videos which brings to mind a second point in favour of the autotune route. The point of these kind of songs is to not only to give giant science nerds like myself nerdgasms, but also to encourage other people to start learning about science.
