- 2.P&A-20The Case of the Lightning TrainPhysics & Astronomy~30 minCan two people watching the same event disagree about which happened first, and both be right? Relativity of simultaneity.
- 3.P&A-23Cartographers of SpacetimePhysics & Astronomy~33 minIf the speed of light never changes, what has to bend instead? Time and space themselves, mapped out on a spacetime diagram.
- 4.P&A-22The Light ClockPhysics & Astronomy~29 minWhy does time slow down the faster you move? The simple geometry hiding behind relativity.
- 5.P&A-25Surveyors of the Curved UniversePhysics & Astronomy~32 minWhy do objects curve through space without anything pushing them? Mass bends spacetime, and things just follow the straightest path through the bend.
- 6.P&A-28Mapmakers of InfinityPhysics & Astronomy~33 minCan you fit all of space and time, including infinity, on a single page? A diagram that maps the whole universe.
