Special Issue Information
Dear Colleagues,
There has recently been a renewed interest in black holes, dark matter and dark energy. This is due to the confirmation of gravitational waves in 2015 from the inspiraling and collision of two black holes, and more recently, the detection of a black hole shadow, published in 2019. Since then, several more verifications have been made. From the theoretical point of view, there are many symmetries relating to black holes, such as black hole symmetry, ladder symmetries, hidden symmetries, gauge symmetries, love symmetries and the symmetry in black hole jets. The cosmic censorship hypothesis also remains an unresolved issue.
In 1998, two teams observing distant supernovae found that they were further than expected, leading to the prediction of the acceleration of the universe at later stages, rather than deceleration, as was previously believed. The most widely accepted explanation for this acceleration is the existence of exotic matter with negative pressure, dubbed dark energy. Dark energy is interpreted as the leftover of mostly cancelled vacuum energy due to spontaneous mirror symmetry breaking. Carroll symmetries, which arise from Poincare symmetry, are expected to be relevant to dark energy. In addition to dark energy, there is also predicted to be dark matter, which is detected by its gravitational effect and not by electromagnetic radiation. Dark matter is expected to comprise around 25% of the matter in the universe, with dark energy 70%, and the remainder baryonic matter.
This Special Issue will accept contributions in the following areas:
- Studies relating to symmetries in black holes, dark matter and dark energy;
- All aspects relating to black holes, including theory as well as observations;
- Theory relating to dark matter, such as candidates, and observations and experiments;
- The acceleration of the universe, the nature of dark energy, modified theories of gravity and dark energy, observational constraints;
- Dark energy and the future of the universe;
- Alternative explanations for dark energy and/or the acceleration of the universe;
- Any other aspects relating to black holes, dark matter, dark energy and the acceleration of the universe at later stages.

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.
