About

The gravitational physics landscape has been evolving rapidly, driven in good part by our ability to study strong-field regions, in particular black holes. Black holes are the most amazing macroscopic objects in the universe. According to Einstein’s General Relativity, their exterior is extremely simple, while their interior holds the failure of the underlying theory. There are thus strong reasons to tests black hole spacetimes, an endeavor made possible by gravitational-wave astronomy. Black hole physics is an active field of research, which witnessed a number of important results in the last few years.

Black Holes Inside and Out will gather some of the world experts in black hole physics, numerical relativity, black hole perturbation theory, data analysis and astronomy to discuss the status of the field and prospects ahead. The meeting will take place at the iconic Black Diamond building from August 26 to August 30, 2024.

The Niels Bohr Institute carries an important legacy in physics and is one of the leading institute in theoretical and experimental physics. Copenhagen is a very enjoyable and beautiful city, and as the capital of Denmark has plenty of wonderful things to do and is easy to reach. and we would be thrilled to organize a small historical tour of the institute. The entire Nordic region has plenty to offer and is a remarkable place for summer vacations.

Code of Conduct: This meeting aims to provide a safe and comfortable environment for scientific interactions. All participants are bound to the Niels Bohr Institute Code of Conduct. If any issues arise during or related to the BHIO meeting, please contact Charlotte Fløe Kristjansen (kristjan AT nbi.dk) or Niels Obers (obers AT nbi.ku.dk).

About our mascot

The Cygnus olor, commonly known as the Mute Swan is the national bird of Denmark. Despite their common name, they are not mute, but neither can they sing as may be implied by the ancient belief in the “Swan song”, according to which a swan will sing a beautiful song as it dies. To this day, no one has offered proof of the existence of a singing mute swan. Already in 77 A.D., Pliny the Elder set about investigating the matter and later wrote in his "Natural History" (Book 10, Chapter xxxii): “Observation shows that the story that the dying swan sings is false.”

Singing or not, its beauty has inspired artists and writers throughout history. Hans Christian Andersen’s “The Ugly Duckling”, which tells the story of an young ungainly cygnet who grows up to be a beautiful swan, is one of the most popular fairy tales of our time.

They are a constant and ubiquitous presence in Copenhagen. Voracious eaters, they can eat up to 3 kg of food per day. In the Lakes, they can often be seen upside down, as they submerge their neck and head to feast on the aquatic vegetation.
