Harry Evett is creating science videos on YouTube, as well as comparisons that show the immense size of some of the objects in our Universe, using 3D computer graphics like the example above. They love creating these videos, and they aim to do it full time eventually. However, producing and rendering 3D graphics is extremely time consuming and hardware heavy, often taking weeks to make a single video. Currently their upload schedule is about one video per couple of months, with big uploads like the annual Universe Size Comparison taking months to make.
