Black Boxes in Black Hole Imaging
Juliusz Doboszewski, Jamee Elder
We investigate the epistemic opacity of computer simulations and machine learning methods in the context of black hole imaging. We argue that there are forms of opacity-including o…
How Theory-laden are Observations of Black Holes?
Juliusz Doboszewski, Jamee Elder
We evaluate the roles general relativistic assumptions play in simulations used in recent observations of black holes including LIGO-Virgo and the Event Horizon Telescope. In both…
Robustness and the Event Horizon Telescope: the case of the first image of M87*
Juliusz Doboszewski, Jamee Elder
We examine the justification for taking the Event Horizon Telescope's famous 2019 image to be a reliable representation of the region surrounding a black hole. We argue that it tak…
On Penrose's Analogy between Curved Spacetime Regions and Optical Lenses
Dennis Lehmkuhl, Christian Röken, Juliusz Doboszewski
We present a detailed analysis of Penrose's gravito-optical analogy between the focusing effects of particular families of Ricci- and Weyl-curved spacetime regions on the one hand,…
Key Science Goals for the Next-Generation Event Horizon Telescope
Michael D. Johnson, Kazunori Akiyama, Lindy Blackburn +42
The Event Horizon Telescope (EHT) has led to the first images of a supermassive black hole, revealing the central compact objects in the elliptical galaxy M87 and the Milky Way. Pr…
The Next Generation Event Horizon Telescope Collaboration: History, Philosophy, and Culture
Peter Galison, Juliusz Doboszewski, Jamee Elder +22
This white paper outlines the plans of the History Philosophy Culture Working Group of the Next Generation Event Horizon Telescope Collaboration.
How not to establish the non-renormalizability of gravity
Juliusz Doboszewski, Niels Siegbert Linnemann
General relativity cannot be formulated as a perturbatively renormalizable quantum field theory. An argument relying on the validity of the Bekenstein-Hawking entropy formula aims…
