One accurate prediction of the General Theory of Relativity is the bending of light in the presence of massive objects, which was experimentally verified during a solar eclipse. The gravitational field of extremely massive objects, such as stars, galaxies, galactic clusters, etc., which wraps time and space around it, causes bending in such a manner that the massive objects act as a lens; this phenomenon is known as gravitational lensing. A natural magnified glass is a powerful tool in studying the properties of the universe and probes to determine the distribution of masses of clusters and galaxies and dark matter. With a strong gravitational lensing effect, distant cosmic objects appear to have multiple images. This can provide valuable information about the distribution of masses, the mass itself, and the shape of the lensing objects. The appearance of much magnified and brighter distant objects makes it possible to detect faint objects. Weak gravitational lensing leads distant objects to appear distorted, which can be probed to infer the distribution of dark matter. The occurrence of lensing on much smaller scales, known as microlensing, can be used to detect and study exoplanets.
This Special Issue will focus on recent research on gravitational lensing providing new insights into some of the fundamental questions in astrophysics and cosmology, including detecting and mapping of the existence dark matter, the topological defects arising due to symmetry breaking in the early universe, the properties of black holes, the nature of the symmetry of large-scale structures, and the evolution and expansion of the universe and properties of gravitational waves and the objects that produce them.
Articles are invited in the following areas:
Strong gravitational lensing, weak gravitational lensing, microlensing, symmetry of large-scale structures, symmetry breaking in the early universe, dark matter, cosmology, gravitational wave, massive objects, large-scale structures, light bending, black holes, galaxy evolution.

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.
