DESCRIPTION:While Carroll geometry has exciting potential applications in 
 the context of flat space holography\, we can also consider an ultra-local
  small-speed-of-light Carroll limits in gravity itself. At first\, this ma
 y seem like an esoteric thing to do\, compared to for example the non-rela
 tivistic expansion of gravity. However\, as it turns out\, Carroll limits 
 in GR lead to remarkable simplifications. In this talk\, I will connect th
 ese limits to BKL limits of gravity\, which similarly describe solvable an
 d rich dynamics\, in the vicinity of singularities. BKL limits have recent
 ly reappeared in the context of AdS/CFT\, and I will reproduce some of tho
 se models from matter-coupled Carroll gravity. Finally\, I will discuss so
 me ongoing work on how systematic Carroll approximations of gravity can be
  used to go beyond existing near-singularity limits.
