Description
Spacetimes, like Minkowski space, are omnipresent in physics. I will
introduce a recent classification of spacetimes that generalizes the
classification of maximally symmetric lorentzian geometries and
includes further physically interesting ones. Among them are galilean,
carrollian and aristotelian geometries for which there is renewed
interest due to applications in holography. These spacetimes posses
infinite dimensional (BMS-like) symmetries which we will also discuss.
