Special Issue Information
Dear Colleagues,
In the last three or four decades, much has happened in cosmology, and we have had the pleasure to find out very surprising things about the world we live in. These decades have also been instrumental in the development of a possible quantum gravity theory, with various approaches being put forward. This has resulted in a vast amount of literature dedicated to finding the interconnections between these two seemingly disparate fields, somehow pointing towards the crucial role which they play in unlocking each other’s problems. The idea that appears to be shaping up is that it is pivotal to understand the nature of gravity at the smallest scales to unlock the prevalent issues of interest in dark energy and matter, among others, and that, at the same time, cosmological probes and observations may provide us with an unexpected and currently underrated arena for testing quantum gravity. Hence, it is important for researchers in these fields to explore these matters further. As such, in this Issue, we would like to include interesting works on the connection between quantum gravity and cosmology, further highlighting these notions and revealing subtleties.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). 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.
