Good videos, with context.

Build a sense of scale before judging a cosmic story

Cosmology & astrophysics videos

Cosmology videos range from historical visualizations to explanations of contemporary theory and speculative futures. Begin by separating a representation of scale from a model of how gravity shapes the universe.

Two visual tools with different jobs

Powers of Ten is the accessible starting point for comparing orders of magnitude. Its changing viewpoint is a design device, not footage of a camera making that journey. ScienceClic tackles a different visualization problem: representing general relativity without relying only on a stretched rubber sheet. Watch for what each picture preserves and what it leaves out. A striking image can support an explanation while still requiring observations and equations to establish its physical claims.

Questions to take into the video

Powers of Ten is a 1977 film, not a current inventory of measured cosmic structure. Long-range cosmic futures elsewhere in the archive include model-dependent and speculative elements.
