Cosmic Distance Ladder
This interactive simulator explores Cosmic Distance Ladder in Astronomy & The Sky. Log distance scale with parallax, standard candles, and Hubble-flow cartoon rungs. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Astronomy & The Sky.

How it works
Distances in astronomy span tens of orders of magnitude. Radar and parallax anchor the nearby end; variable stars and supernovae extend the ladder through galaxies; redshift maps the expanding universe at the largest scales.
