About this person
Sabine Hossenfelder spent two decades as an academic theoretical physicist before stepping into a different arena entirely. In the early 2020s she turned to YouTube, where her channel grew to 1.79 million subscribers by September 2026. As a science communicator and writer, she has taken aim at the culture and assumptions of fundamental physics itself, arguing points that make her former colleagues uneasy. The critiques have sparked wider debate about what science communicators owe the public and whether challenging institutions strengthens or weakens trust in science.
