Description
The Dynamical Cobordism is a powerful analysis to explore infinite distance limits in the scalar field space for general theories. The method is general and it is crucially independent of supersymmetry. We describe spacetime dependent configurations in which some scalar fields reach infinite distance in the field space at finite distance in spacetime, where the metric solution hits a curvature singularity and the spacetime ends, providing a dynamical realization of the Cobordism Conjecture. At the spacetime boundary, the End of The World brane encodes the information of the corresponding infinite distance limit and allows to explore the Swampland Distance Conjecture, even in the presence of scalar potentials. We consider theories with different kinds of End of The World branes, associated to different scalars, and we study the physics at their intersection by constructing explicit local solutions. These configurations are interesting to study many different physical setups, such as the network of infinite distance limits in Calabi-Yau moduli spaces, or the collision of bubbles of nothing in cosmology.
