What is Scale of the Universe?
Scale of the Universe is a browser toy that shows how big things are by letting you zoom through them. It runs from the smallest particles up to the largest galaxies, with familiar objects along the way for comparison. Clicking an object brings up a short note about it.
Cary Huang first made it as a Flash app in 2010, and a newer team remastered it with modern code and updated discoveries. The site says schools use it as a learning tool. It also has resources, a wiki and a community section, and a small shop that sells a dinosaur plush.
