Singularities in Spacetime

Dear Colleagues,

This Special Issue will be focused on singularities in relativistic spacetimes. Papers on the definition, existence, and nature of singularities are welcome. Boundary definitions may be explored together with the location of singularities in relativistic spacetime manifolds. Theorems on the existence of singularities in general and discussions of the various types of singularities (quasiregular, nonscalar curvature, and scalar curvature) would be of interest together with the use of invariants, both scalar polynomial and Cartan, to indicate curvature singularities. The behavior of classical and quantum particles and fields in singular spacetimes could be explored to further our understanding of the singularities present, both in exact solutions to Einstein’s equations or alternative theories and within our physical universe. Finally, approaches to quantum gravity and how they can erase classical singularities would be appropriate.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Universe is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
