## Prompt

Who was awarded the 2020 Nobel Prize in Physics, and for what? Cite your sources.

## Response

The 2020 Nobel Prize in Physics recognized three scientists for groundbreaking contributions to black hole research: Roger Penrose for proving that black holes are a prediction of general relativity, and Reinhard Genzel and Andrea Ghez for discovering the supermassive black hole at the center of our galaxy.

**Individual recipients and their contributions**
**Roger Penrose**
Awarded half the prize "for the discovery that black hole formation is a robust prediction of the general theory of relativity." His work demonstrated that black holes naturally arise as solutions to Einstein’s equations.

**Reinhard Genzel and Andrea Ghez**
Awarded the other half jointly "for the discovery of a supermassive compact object at the centre of our galaxy." Their decades-long astronomical observations tracked stars orbiting an invisible, extremely heavy object—Sagittarius A*—providing the strongest evidence for a supermassive black hole.
