  Dear Colleague,

  On behalf of the Conference Organizing Committee PIRT-2023 we would like to formally invite you to participate at the Physical Interpretations of Relativity Theory conference this year in the Bauman University, Moscow during the period July 3rd to 6th, 2023.

  The PIRT Conference is an international scientific event that originated in 1988 and was first held at Imperial College in London once every two years, and since 2003 it has been held at Bauman University in Moscow. The main objectives of the conference are to discuss the physical, geometric, and mathematical interpretation of the theory of relativity, its experimental verification and discussion of alternative theories of gravity, optical methods for detecting gravitational waves, new effects of moving-media optics and relativistic electrodynamics, as well as astrophysical observations and space experiments. The XXIIth PIRT-2021 conference was held at a high international scientific level. 122 scientists from 21 countries attended the conference. There is more information on the website .

  The Conference Program of the PIRT-2023 will include papers dealing with the following major themes:

Gravitation, cosmology and large-scale structure
Gravitational waves and experimental tests of the relativity theory
Relativistic electrodynamics
High energy astrophysics
Modern problems of classical and quantum field theory



Abstracts (one page of text) in English offered for inclusion in the PIRT-2023 Program should be sent to the Conference Committee before April 1st, 2023.
(5-10 pages of text including figures) in English should be sent to the Conference Committee before August 1st, 2023.

According to the results of the conference some papers will be selected for publishing in a separate issue of Journal “Space, time and fundamental interaction”. The articles should be thoroughly revised and put into shape in according to requirements.


Information regarding registration fees will be posted later.


We suggest you to reserve a room by yourself in the Izmailovskii Tourist Hotel Complex (Izmailovskoe Shosse, 71, 3V, Moscow, 105187. E-mail:, or
