An uncertain view of the invisible

Changing Perspectives is a monthly talk series dedicated to stories of transformation. Each event invites an inspiring guest to share how a shift in perspective opened unexpected paths, new discoveries, or even a new way of living. These talks are not about abstract ideas alone, but about real turning points; an open invitation to reflect on how even small changes in our perspective can spark creativity, courage, and new directions in life.

The series is initiated and hosted by Dr. Thalia Traianou, astrophysicist and postdoctoral researcher at the Interdisciplinary Center for Scientific Computing (IWR), Heidelberg University, and member of the Philosophical Society of Heidelberg.

✨ The upcoming Talk
An uncertain view of the invisible
In this talk, Dr. Roman Gold will guide us through the unusual challenge of studying something that cannot be seen. He will show how imaging black holes requires techniques unlike any used in ordinary astronomy: combining telescopes spread across the Earth, reconstructing pictures from incomplete and uncertain data, and interpreting results in a domain where our best physical theory eventually breaks down. By tracing how scientists build knowledge in the face of invisibility and ambiguity, he will reveal not only how black hole images are made, but also how these methods reshape scientific reasoning itself and influence how such discoveries are communicated to the public.
