As Editor-in-Chief of the journal Universe (ISSN 2218-1997), it is my honor to invite you to join the 1st International Electronic Conference, Universe 2021: 1st Electronic Conference on Gravitation, Cosmology, Field Theory, High Energy Physics, and Astronomy, from 22 to 28 February 2021, which will enable you to share and discuss your most recent findings with the worldwide community of scientists and researchers in these fields. At this point of restricted travel and personal contact, it is a pleasure to still be able to collaborate electronically via this online venue. This internet conference is designed to allow you to present your research to colleagues and to interact as fully as possible with all those involved in it. I also hope you will meet old friends and make new ones here. There will be many fascinating papers to spark everyone’s interest. I hope this conference will bring together major contributions at the forefront of research in the fields of gravitation, cosmology, field theory, high energy physics, and astronomy, and I am confident that yours will be among them. Universe 2021 will make your presentation accessible to hundreds of researchers worldwide, with active engagement of the audience in question and answer sessions and discussion groups that will take place online. Submitted abstracts will be reviewed by the conference committee. The authors of accepted contributions will be invited to produce an extended abstract for the conference proceedings along with a slide presentation of their work. Following the conference, outstanding contributions will be invited to be submitted for publication in the main journal.
The conference has been divided into ten themes. Please submit your articles as soon as possible, indicating which theme you think best fits your submission.
