Special Issue Information
Dear Colleagues,
In recent years, groundbreaking experimental advances have propelled a transition of gravitational physics in the strong field regime from a mostly theoretical domain into an increasingly experimental science. The detection of gravitational waves, the imaging of the shadow of a supermassive compact object, and the observation of flares near the center of the Milky Way have provided unprecedented opportunities to test the limits of theoretical physics, including the nature of one of the most fascinating astronomical models, the wormhole, a passage through spacetime that could potentially enable travel over large distances or even through time. Current research on wormhole models faces significant challenges, from the requirement of unobserved matter forms in classical general relativity to stabilize the wormhole throat, to modifications of gravitational theory itself, alongside other physical and mathematical limitations. As such, the development of physically relevant wormhole models remains a timely and relevant task in the field of theoretical physics.
The goal of this Special Issue is to gather a compilation of manuscripts focused on the development and testing of suitable wormhole models that are potentially compatible with state-of-the-art experimental and observational results in order to assess the plausibility of the existence or construction of wormholes in our universe.

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. 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.
