The Scale of the Universe is an interactive online visualization tool and website first created in 2010 by Chinese-American twins Cary and Michael Huang, based in Moraga, California.

[1][2][3][4][5] Released on Newgrounds and the Huang brothers' web page, it features a scrollbar that players can use to navigate through orders of magnitude and view various objects within such size ranges.

Sliding the scrollbar to the left and right causes the screen to zoom in and out respectively, utilizing resolution independence in the process.

[1] In 2012, Cary and Michael Huang released a sequel titled The Scale of the Universe 2, in which clicking on objects brings up infoboxes that display information about them.

[10][11] The main-belt asteroid 10003 Caryhuang was officially named by the International Astronomical Union on June 16, 2021, partly in recognition of Cary Huang's involvement in The Scale of the Universe.
