installation, 2017

Dark matter is undefined material that scientists cannot see even with the use of the most advanced technology, for example of radio-telescopes or optical telescopes. Dark matter is not anything known and has never been directly observed. It is one of the biggest mysteries of astrophysics today. Its existence has been inferred from gravitational effects, such as the movements of visible matter (stars, gas, dust), the bending of light on its way from source to observer (gravitational lensing), its influence on big structures such as galaxies, and its impact on the cosmic microwave background, or CMB. Dark matter is part of space and is found everywhere in the universe.

The installation Black Trough conjures up the omnipresence of dark matter all around us from the standpoint of art, and with the use of a certain fluid presents its entwining of the galaxies, the stars and everything else that we can detect with the naked eye or with the use of the technology available today.

Fluids are divided into what are called Newtonian and non-Newtonian. Newtonian fluids are characterized by having a constant viscosity notwithstanding any force that is exerted upon them. Water is an example: its viscosity is always the same and it flows equally irrespective of any force exerted. The properties of non-Newtonian fluids are just the opposite; their viscosity changes with a modification of the force that we exert on the fluid. An example is a fluid that is presented in the installation Black Trough. It is chosen to represent dark matter because of its interaction with any visitors who happen to be in its vicinity. It is viscose when the force we exert upon it is small, but when the force is increased, the viscosity decreases. The visitors can touch the substance and effect it more or less strongly in order to study its properties. They can also place various objects upon it and study the way in which this fluid withdraws into its interior.


Ana Sladetić (HR)

Ana Sladetić was born in 1985 in Vukovar. She graduated in 2009 at the Academy of Fine Arts at the Universityof Zagreb, at which she obtained her doctorate in 2015, supervised by Ante Rašić and Leonida Kovač.

She has taken part in numerous collective and individual exhibitions in Croatia and abroad. She has won a number of prizes for her work, including the best work prize at the exhibition World Youth Art Festival (Seoul, South Korea, 2017), an Ex aequo at the 25th Slavonia Biennial (Museum of Fine Arts, Osijek, 2016), the first prize at Celebrate Originality – Adidas in association with the Street Art Museum (Zagreb, 2010) and the Grand Prix of the 30th Young Artists’ Salon (HDLU, Zagreb, 2009). She has given several public lectures and held workshops in association with domestic and foreign cultural institutions, museums and galleries. She has done further studies and been on artistic residencies in Germany, Belgium, France, Finland and the USA. She is an assistant professor at the Academy of Arts and Culture at the Josip Juraj Strossmayer University of Osijek.


Nika Jurlin (HR)

Nika Jurlin was born in 1990 in Brežice, Slovenia. She is currently in her final year of a course in physics at the Natural Science and Mathematics Faculty in Zagreb, after which she will take a post-graduate course at the Kapteyn Astronomical Institute of Groningen University, the Netherlands. She began to be interested in astrophysics at university, where with the mentorship of Associate professor Vernesa Smolčić she began a research career studying very distant galaxies. During her studies, she spent several months at the astronomical institute Astronomico di Bologna in Italy, at Oxford University, UK, and at the École normale supérieure de Lyon in France, where she worked on scientific projects from the domain of astrophysics, from optical to radio-astronomy.
