Seminarium Teorii Względności i Grawitacji

The spacetimes with the NUT parameter are commonly associated with the unwanted defect in the form of the singular axis of symmetry. On the other hand, introducing the NUT parameter to the Schwarzschild solution completely regularizes the singularity at r=0. Luckily Misner found a way to also cure the singularity at the axis by compactifying the orbits of the time symmetry. I will discuss how these results extend to spacetimes with the Kerr parameter, cosmological constant and acceleration and the consequences for horizons and cosmology.
