DESCRIPTION:Cosmological collapse\, where gravitational pull overcomes the
  universe’s expansion\, can create primordial black holes or other bound
  structures. The ultimate fate of such a collapse depends on the initial d
 istribution of matter and its equation of state\, as pressure counteracts 
 the gravitational infall. Then\, in the dust case\, where there is no pres
 sure\, shouldn’t a black hole always form? In this talk\, I will attempt
  to answer this question using numerical relativity simulations\, discussi
 ng the challenges of this problem and the progress we have made so far. Ad
 ditionally\, as this is in full GR\, it presents an opportunity to charact
 erise the cosmological spacetime\; therefore\, I will also describe this u
 sing gravito-electromagnetism and Weyl invariants.
