    In 2019 newspapers excitedly reported that astronomers had finally “photographed” the black hole M87*. This famous image does not fit our usual definitions of photography as it used complex computer algorithms to fashion an image from collected data. Why and how is this image described as a “photograph?” This panel looks to examine objects that are named, described, titled, situated, or conventionally understood as “photographs” despite not using a camera, not recording light waves, or using other mechanical or digital methods to produce an image. Rather than being a novel phenomenon or problem, artists and scientists have struggled to define and name photography since the inception of the medium. From nineteenth-century photomechanical processes and photo-sculptures to AI image-making and astronomical visualizations, such objects are often subsumed into the category of “photography.”

    Investigating photography from this set of examples, this panel asks: What kind of objects/processes have been called a photograph? Which features and technologies are used to define the medium? How can they reimagine the medium’s history and future? Contributions might explore the reception of objects as “photographs,” the aestheticization or mediation of alternative “photographic” methods, the use of photographic processes in science, or the circulation and transmission of photographs through other media. This panel seeks to bring together papers across geographies and time periods and encourages presentations that engage with interdisciplinary perspectives including scholars working on the definitions, devices, and debates surrounding photographic methods from the nineteenth century to the contemporary.

    Abstract: By most counts, the image published by the Event Horizon Telescope of a black hole is not a photograph. Part of what has made black holes undiscoverable, beyond their being at twenty-six thousand light years from Earth is that they are understood to swallow rather than emanate light, with patterns in light’s absence making them discoverable. What makes the black hole photograph an image at all might be an equally pressing question, given that the volume of data transmission their observation requires, currently assessed at sixty-four gigabits per second at speeds that exceed earlier interferometric systems ninety-thousand-fold. The black hole photo is not just of a theoretically hyperbolic object, it also is a supermassive entity itself—of data. Drawing on the so-called Beckenstein entropy bound on information, according to which the maximum amount of data that can be put in a volume is framed in terms of a black hole, this paper considers black holes as expanding the imaginary of data to off-world frontiers in response to a crisis in both the perceived sustainability of data and its intelligibility to human perception. It looks at work by artists seeking to subvert data-saturated systems by targeting their inner propensities toward forgetting, rot, and decay, such as Hito Steyerl’s notion of impoverished images, Linda Dounia Rebeiz’s synthesis of non-existent memories, and Mimi Ọnụọha’s filling of “blank [sic] holes” with missing data. Black holes are thus presented as both hyperbolic and tactical in image theory.

    Black Hole | Black Box: Limits, Opacity, and the Unknown Across Art, Science, and Media

    Date: March 19-20, 2026

    Location: Bibliotheca Hertziana, Max Planck Institute for Art History
    Villino Stroganoff, Via Gregoriana 22, 00187 Rome (Public event without registration)

    Speaker: Dr. Eszter Polonyi

    This conference examines limits, opacity, and the unknown by bringing together two notions from very different domains: the black hole of astrophysics and the black box of computation in which theoretical and empirical boundaries are reached.

    This conference examines limits, opacity, and the unknown by bringing together two notions from very different domains: the black hole of astrophysics, where empirical and theoretical boundaries are reached, and the black box of computation and technology, whose inner workings are inaccessible even as they produce observable effects. Rather than treating them simply as objects of absence, the conference approaches black holes and black boxes as conceptual, aesthetic, and methodological frameworks for exploring what is partly unseeable, partly generative, and always challenging the thresholds of knowledge and perception. By juxtaposing perspectives from art, media, and science, we want to investigate how these frameworks allow us to study, imagine, and engage with phenomena that elude us.

  • Black Holes and «One Hundred Thousand Suns»

    Black Holes and «One Hundred Thousand Suns»

    Seminar and workshop

    Date: Nov. 27, 2025, Villino Stroganoff, Via Gregoriana 22, 00187 Rome and online

    Location: Bibliotheca Hertziana, Max Planck Institute for Art History, Rome

    Speakers: Dr. Eszter Polonyi, Dr. Sašo Grozdanov, and Rohini Devasher

    In this interdisciplinary seminar, an artist, a historian and a physicist come together to explore how visual methods produce knowledge about astronomical phenomena. How does the human observer approach the unseeable, the unknowable? In 2019, the iconic visualization of a black hole was released by the Event Horizon Telescope. This builds upon a long history of visual methods in observing celestial objects, from drawing to analog and digital photography. The seminar revolves around Dr. Eszter Polonyi and Dr. Sašo Grozdanov’s work on black holes and photography, and on Rohini Devasher’s artistic practice on portraying the Sun. We explore visual methodologies and interdisciplinary work processes – spanning art, physics, and history – through the lense of the astronomical image.

    Notes from the Extradate Era

    In 2005, two concerned civilians filed a lawsuit to shut down Europe’s Large Hadron Collider (LHC), the world’s largest scientific experiment designed to investigate quantum phenomena such as supersymmetry, extra dimensions, and dark matter. Their complaint was that, running at roughly 7 million times the energy per year of a single high-energy beam circulating within it, the LHC operated at energy levels that risked opening a black hole that would swallow the planet. The case was dismissed in 2008 on the basis of technical rather than scientific terms. Among the reasons given were absurdities to which the lawsuit gave rise within legal procedure, including the difficulty of finding a witness and producing a cost-benefit analysis in which the projected scientific outcomes of the experiment were measured against the future of the entire planet and “life as we know it.” Often referred to colloquially as the “doomsday lawsuit,” this case testifies to a newfound difficulty in adapting technical discourse to the planetary framework of the Anthropocene (Crutzen & Stoermer) within which the human scientific and cultural imagination has been operating over the last century.

    This paper considers the fascination with black holes across technical, scientific and artistic types of imagination as a symptom of cognitive overwhelm at the level of data management (B. Bratton, T. Paglen, Y. Hui). At a time when the artificially intelligent agents collecting, storing, mining, and processing are starting to exceed planetary resources, hungry black holes and other extraplanetary phenomena have taken over from earthbound “clouds” (JD Peters) as metaphors of technical and conceptual expansion. The paper examines the off-world frontiers of data collection of what it calls the “Extradata Era” in contemporary photography and theoretical physics.

  • WHAT IS A PHOTOGRAPH?

    WHAT IS A PHOTOGRAPH?

    Lecture //

    We are excited to announce the inaugural lecture of the Black Hole Photography Lecture Series next week Wednesday. 

    Date: Wednesday June 11, 2025  Time: 11-12

    Location: Large Lecture Hall, Erjavčeva ulica 23., ALUO, Univerza v Ljubljani, Ljubljana 1000.

    SPEAKER: Jennifer Marine, MA, University of Virginia, Art History

    “In 2019, astronomers captured the now-iconic image of black hole M87—a photograph unlike any other. Made with no camera or film, how can such an image still be called a photograph?” Join us for a thought-provoking exploration of the fluid boundaries between photography and scientific imaging. This talk traces a fascinating arc from Margaret Watts-Hughes’s “Voice Figures” and Robert Williams Wood’s sound wave photography, to the radio-based imaging of deep space, interrogating the very definition of a photograph. Discover how light and sound have long been entangled in the visual history of science and art—blurring categories, challenging conventions, and reshaping how we see (and hear) the world.

    Black holes, the edge of knowledge, and what is knowable:

    Past lessons and future challenges

    Date: 17 November 2025, 2:15 p. m.

    Location: J19/F1, Faculty of Mathematics and Physics, Jadranska ulica 19, Ljubljana

    Speaker: Assoc. Prof. Dr. Sašo Grozdanov

    Black holes are probably the most fascinating objects in nature. Their study places us at the frontier between known and unknown physical laws—at the intersection of classical General Relativity, quantum physics, and the still-developing theory of quantum gravity. In the first part of this talk, I will discuss what black holes are, what we currently understand about them, what remains mysterious, and how they fit into the string-theoretic holographic (AdS/CFT) duality, which connects certain theories of quantum gravity to quantum field theories. I will then present some of my past research results that stem from studying black holes and their relation to quantum physics through holography. These include statements about hydrodynamics, many-body localisation, heavy-ion physics, and quantum chaos, all in strongly interacting quantum field theories. Finally, I will outline several foundational open problems in theoretical physics and reflect on the connections between physics, philosophy, and art.
