From quarks to the observable universe
Size of Life is a visual perspective tool that helps you comprehend the scale of things in the universe — from subatomic particles to the observable universe itself. Scroll through an interactive visualization that puts size into perspective.
Navigate through different scales of the universe using an interactive slider. Compare the sizes of atoms, cells, animals, planets, stars, and galaxies. Each object is shown with real proportional sizing to help you grasp the true scale of our universe.
Humans have poor intuition for very large and very small numbers. We can easily picture 10 apples but struggle to comprehend 10 billion stars. Size of Life bridges this gap by providing visual comparisons that make cosmic and microscopic scales tangible.
