WebbBlack holes are some of the most fascinating and mind-bending objects in the cosmos. The very thing that characterizes a black hole also makes it hard to study: its intense gravity. All the mass in a black hole is concentrated in a tiny region, surrounded by a boundary called the “event horizon”. Nothing that crosses that boundary can return to the … Webb12 apr. 2024 · Narrator: However, in the 1970s, the physicist Stephen Hawking proposed a startling new theory about black holes. He showed that black holes are not truly black after all, but instead emit a faint glow of radiation known as Hawking radiation. Narrator: This radiation is thought to be created by the interaction of particles near the event ...
