The Biggest Star In The Universe Is Too Small

The video explores the star R136A, initially thought to be over 2000 solar masses but later found to be a cluster of stars. R136A1, the most massive star in the cluster, challenges our understanding of stellar physics and the Eddington limit. The video discusses telescope techniques like speckled imaging, the role of Population III stars, and the significance of supernovae in metal formation. The shrinking mass of R136A1 raises questions about the origins of metals in the universe, suggesting a need to revisit current astronomical theories.
