Holy quantum singularities! Thanks to new calculations by Hubble Fellow and CAS Institute for Astrophysical Research associate Simon Portegies Zwart and a Drexel University colleague, physicists will soon be able to detect the strong gravitational waves produced by colliding pairs of black holes.

In previous work, two of us have proposed a ``minimal subtraction'' prescription for the simplest class of such systems, involving Hamiltonians with only one singular term. ... Key words: Penrose limit and pp-wave background; M(atrix) Theories; Spacetime Singularities...

Activity on Frobenius manifolds, quantum cohomology, and singularities ... Frobenius manifolds turn up in quantum cohomology, where they encode information of Gromov-Witten invariants of genus 0, and in singularity theory, as base spaces of unfoldings of singularities. Isomorphism of certain of the Frobenius manifolds on...

Title:; Towards quantum cosmology without singularities ... We show that after quantizing the scalar fields the quantum corrections smooth out the singularities. In addition, we argue that the incorporation of nonperturbative quantum corrections form a dilaton potential.

A singularity is a term commonly used by 24th century Federation starship personnel to refer to a point or region in the space-time continuum where normal physical models do not apply and extraordinary amounts of gravitational forces are typically present. ... There are relationships between singularities and time.
