What were Stephen Hawking's contributions to the understanding of black holes and cosmology?
Understand the Problem
The question is asking for an understanding of Stephen Hawking's contributions to physics, particularly related to black holes and his popular science writing.
Answer
Hawking proposed Hawking radiation, worked on singularity theorems, and popularized science with "A Brief History of Time."
Stephen Hawking made several major contributions to the understanding of black holes and cosmology. He proposed the theory of Hawking radiation, showing that black holes can emit radiation due to quantum effects. He also worked on the Penrose-Hawking singularity theorems, which provide evidence for the formation of black holes in the universe. Additionally, his book "A Brief History of Time" popularized complex cosmological concepts.
