Special Issue Information
Dear Colleagues,
It’s fifty years since Stephen Hawking laid out the physics of primordial black holes (PBH) and fifty years since the cold dark matter paradigm became the standard model for the formation of structure in the universe. It’s time to see if they can be linked. There is one overwhelming obstacle: no PBH has yet been detected or confirmed.
Theoretically, PBHs have a mass range from the Planck mass at 21 μg to supermassive black holes at 107 solar masses. Their Hawking radiation would range from many PeV to radio wavelengths. Their gravitational radiation would arise from a density (of up to 1011 c6/G3 gm/cc) far into the quantum gravity regime. It is time to systematically review their detectability across the electromagnetic and gravitational wave spectra.

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.
