Conference GR20/Amaldi10 in Warsaw

0

Over this week Warsaw is the centre of attention for all physicists involved in gravity. Nearly 900 scientists are participating to the XX  International Conference on General Relativity and Gravitation (GR20), being held in conjunction  with the 10th Edoardo Amaldi Conference on Gravitational Waves (Amaldi10).

International Conferences on General Relativity and Gravitation are held every three years under  the auspices of the International Association of the Theory of Relativity and Gravitation. This year,  the twentieth conference is being held together with the biennial Edoardo Amaldi Conference on  Gravitational Waves organised by the International Gravitational Waves Committee. The Polish  organizers of the GR20/Amaldi10 conference are the University of Warsaw and the Polish Society  on Relativity. The patrons of the conference are the President of the Polish Academy of Sciences and the Rector of the University of Warsaw.

Yesterday, the Conference was opened by Professor Jerzy Lewandowski, President of the  Polish Society on Relativity, Professor Michał Kleiber, President of the Polish Academy of  Sciences, Professor Malcolm MacCallum, President of the International Association of Relativity  and Gravitation, and Professor Eugenio Coccia, president of the International Committee on  Gravitational Waves. The conference will run until July 13.

“The combined GR20/Amaldi10 conference is an unprecedented event, which has attracted close  to 900 researchers in various theories of gravity, gravity waves and related astrophysical issues to  Warsaw. Over the next week we will see major physicists from nearly 50 countries around the  world,” says Professor Jerzy Lewandowski (FUW), Chairman of the Organizing Committee.  Every day the GR20/Amaldi10 conference programme includes a morning session consisting of  consecutive hour-long lectures by eminent scientists, and a number of parallel afternoon sessions,  consisting of many 15-minute presentations.

During the conference, physicists plan to discuss string theory and loop quantum gravity, the  properties of gravitational waves, current and future gravitational wave detectors, and the latest  measurements of the cosmic microwave background. Topics of astrophysical discussion will  include binary systems of neutron and strange stars, stellar collisions, the formation of  supermassive black holes in galactic nuclei, the processes by which black holes combine, and their  interaction with dark matter.

The researchers will be looking for answers to many intriguing questions. What is the geometry of  the Universe? What is the structure of the cosmic vacuum? Are the effects of gravity and those  observed during acceleration definitely the same? Is it possible to build a gravitational wave  observatory the size of a galaxy? Is it possible to observe gravitational waves associated with  gamma-ray bursts? How big is the population of black holes near the galactic nucleus? The topics  discussed at the conference will also include some speculative issues, such as tunnelling through  the event horizons of black holes in higher dimensional space-time, the formation of wormholes  and the study of their properties, and even the formation of baby universes.  At the conference, Professor Carlo Rovelli, a prominent expert in the field of loop quantum gravity,  will deliver a public lecture – the “Quanta of Space” – on July 9 at 20:30. The lecture, in English, will be held in the Auditorium Maximum of the University of Warsaw at 26/28 Krakowskie  Przedmieście.
 
The International Conference on General Relativity and Gravitation is being hosted in Poland for  the second time. More than half a century ago, in July 1962, the third conference of its kind took  place in Warsaw and Jabłonna. It was then organized by the prominent Polish physicist Leopold  Infeld, a colleague of Albert Einstein’s. Guests of the conference included such physicists as Paul  Dirac, Richard Feynman and John Archibald Wheeler.

“The conference in Jabłonna was a milestone for research in the field of quantum gravity,  gravitational waves, astrophysics and mathematical methods in the theory of relativity. We very  much hope that the present conference will be equally significant for the development of the world  of physics and the consolidation and expansion of environmental Polish relativistic physics,”  concludes Professor Lewandowski.
