Abstract

Space obeys the rules of Euclidean geometry. Spacetime obeys the rules of a new kind of geometry called Minkowskian geometry.

Learning Outcomes:

• Triangles in spacetime obey a Pythagoras-like theorem, but with an unusual minus sign.

• The true nature of time as geometrical distance in spacetime.

• How to analyse and resolve the Twins’ Paradox using spacetime diagrams in combination with Minkowskian geometry.
