## Prompt

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

## Response

The 2020 Nobel Prize in Physics was awarded to three scientists for discoveries about black holes [nobelprize.org](https://www.nobelprize.org/prizes/physics/2020/press-release/).

**Roger Penrose** received one half of the prize "for the discovery that black hole formation is a robust prediction of the general theory of relativity" [nobelprize.org](https://www.nobelprize.org/prizes/physics/2020/summary/). Penrose, born in 1931 in Colchester, UK, is a professor at the University of Oxford.

**Reinhard Genzel** and **Andrea Ghez** shared the other half jointly "for the discovery of a supermassive compact object at the centre of our galaxy" [nobelprize.org](https://www.nobelprize.org/prizes/physics/2020/popular-information/). Genzel, born in 1952 in Bad Homburg vor der Höhe, Germany, is Director at the Max Planck Institute for Extraterrestrial Physics and Professor at UC Berkeley. Ghez, born in 1965 in New York, is a Professor at UCLA.

Together, their work demonstrated that black holes are both a theoretical prediction of Einstein's general relativity and an observed phenomenon in our galaxy's center, providing crucial evidence for one of the universe's most exotic objects.

What specific aspect of black hole physics or these laureates' research methods interests you most?
