Episode notes
Stagnation, Not Crisis
- Hossenfelder prefers "stagnation" to "crisis" when describing the state of fundamental physics.
- "Stagnation" more accurately reflects the lack of progress, unlike "crisis," which implies potential breakthroughs.
Need for Experimental Data
- Progress in fundamental physics like quantum gravity and dark matter requires experimental data.
- Hossenfelder points out that without data, theoretical physics becomes overly reliant on mathematical speculation.
Progress vs. Fundamental Progress
- Hossenfelder views advancements like the amplituhedron as interesting but not fundamental progress.
- They improve understanding of existing theories but don't address the major open questions.
