Cosmic Distances

A tool to explore the vast scales of our universe, calculating distances, travel times, and generating easy-to-understand explanations with AI.

Explore the Scales of the Universe

Visualizing the vastness of space and time, from the blink of an eye to the age of the universe.

A Journey Through Time
This is a logarithmic scale, meaning the distance between marks represents a multiplication (e.g., 10x), not an equal addition. This allows us to visualize vast ranges from a fraction of a second to billions of years.

A Ladder of Distances
This is a logarithmic scale, meaning the distance between marks represents a multiplication (e.g., 10x), not an equal addition. This allows us to visualize vast ranges from human height to the size of the universe.
