Astronomy Quote by J. Robert Oppenheimer
“When all thermonuclear sources of energy are exhausted a sufficiently heavy star will collapse. Unless fission due to rotation, the radiation of mass, or the blowing off of mass by radiation, reduce the star's mass to the order of that of the sun, this contraction will continue indefinitely.”
About This Quote
Source Lecture: Scientific American article on stellar evolution, 1960s
A massive star will keep collapsing after nuclear fuel runs out unless it loses enough mass through various processes, preventing endless contraction.
In simple terms: Stars collapse without enough mass loss.
Key Takeaway
Prevent mass loss to avoid infinite collapse.

Questions to Reflect On
- What processes can effectively reduce a star's mass?
- How does rotation influence collapse?
A Different Perspective
If mass loss mechanisms are insufficient, collapse may still proceed to a black hole.
