Special Issue Information
Dear Colleagues,
This Special Issue will cover different aspects of quantum effects in general relativity. Understanding how to merge quantum mechanics and general relativity is one of the deepest problems in modern theoretical physics. The main issue is that Newton’s constant, which fixes the strength of the gravitational interactions, is dimensionful. In that sense gravity according to Einstein is very different from other fundamental interactions whose strengths are fixed by dimensionless coupling constants. This leads to the well-known problem of the non-renormalizability of Einstein’s theory, at least in perturbation theory. At this stage, it is not clear whether solving this problem will require expanding quantum physics or gravity or giving up the notion of point particles. One thus needs to remain open-minded and agnostic on how to resolve this fundamental problem. This Special Issue will present the state of the art in this field and is open to all approaches to quantum gravity. We welcome submissions of, either research or review, papers dealing with quantum effects in general relativity very broadly defined. Papers describing applications of quantum gravity to particle physics, cosmology, or astrophysics including black holes are also most welcome.

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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
