   If we were in a black hole with mass M ~ 10^{53}kg of mass   
   the horizon would be around where the cosmological horizon   
   is. We might locally find conditions not too different from   
   what we now see. However, black holes have a Weyl curvature   
   tensor components. These are ~ GM/c^2r^3 and positive along the   
   radial direction and negative along distances perpendicular   
   to the radius. This means there would be one direction where   
   galaxies are red shifted and a planar set of directions   
   where galaxies are blue shifted. The large scale structure   
   of the universe would be very different.
