Episode notes
Cosmic Anomalies
- The Standard Cosmological Model, based on Einstein's theory, describes the universe's history well.
- However, recent evidence suggests missing pieces, like galaxies moving faster than explainable and less cosmic clumping.
Mercury's Orbit Anomaly
- A tiny anomaly in Mercury's orbit puzzled 19th-century astronomers.
- Einstein's general relativity explained this anomaly, leading to groundbreaking discoveries like black holes.
Scientific Skepticism
- Scientists should be cautious and skeptical, especially with their work.
- Anomalies can lead to breakthroughs, but are often red herrings from statistical flukes or errors.
