 >Towards a Spacetime Intrinsic Flat Convergence</a>\nby Christina Sormani 
 (City University of New York) as part of JoMaReC - Joint Online Mathematic
 al Relativity Colloquium\n\n\nAbstract\nIn order to define a spacetim
 e intrinsic flat convergence\, Carlos Vega and I defined the null
  distance to convert spacetimes endowed with regular cosmological time
 s into metric spaces. Currently Anna Sakovich and I have been explo
 ring the properties of these metric spaces. We can prove that on
 e can recover the causal structure from the null distance and the cosm
 ological time. We can prove that a distance-preserving time-preserving bij
 ection between the spacetimes endowed with a null distance is in fact a Lo
 rentzian isometry under suitable conditions.  Next we will prove there ar
 e biLipschitz charts so that we may view the spacetimes endowed with the n
 ull distance as integral current spaces. This allows us to rigorously def
 ine the spacetime intrinsic flat convergence for spacetimes that a
 rise as the future maximal developments of initial\ndata sets. For
