The two began their project of scaling the solar system by having a marble represent the earth. At that size, after doing some calculations, they found that they needed roughly 7 miles of space to get in the orbit of Neptune which is the outermost planet since Pluto got demoted. Using GPS calculations and glass spheres lit by LEDs they were able to shoot a time-lapse that accurately reflects the distance of each orbital path in the Black Rock Desert in Nevada. The scale is roughly 1:847,638,000. Fucking mind blowing.
