Many thanks to Ryan Bertram (Astro A100 student), who introduced me to this neat YouTube video (courtesy of Rob Bryanton, Canadian author) that discusses the ten possible dimensions of our universe.
Many thanks to Tim McCormick (Astro A100 student), who introduced me to this fantistic webpage that models early solar system formation.
Many thanks to Elizabeth Potter (Astro A105 student), who showed me this neat webpage highlighting the relative sizes from the Local Group down to Quarks (and the corresponding orders of magnitude, or powers of ten)
