Black Holes and Space-Time: A Fact Stranger Than Fiction
In Black Holes and Space-Time: A Fact Stranger Than Fiction, narrator Kate Yule describes Stephen Hawking's greatest work on black holes, where gravitational fields are so strong that nothing can get away, and the denser matter becomes, the more space-time is warped. This video is excerpted from BBC’s Einstein & Hawking: Masters of Our Universe, a mind-bending documentary that tells the story of how the two most famous scientists of the 20th Century transformed our understanding of the Universe and changed the world.
Lesson Express
Q: What was Stephen Hawking’s first big paper about?
A: Hawking’s first big paper provided theoretical proof that the Universe began with the “Big Bang.”
Q: How does Stephen Hawking describe a black hole?
A: Hawking described a black hole as a literal hole in space that things can fall into but not come out of because the gravitational hold is so strong.
Q: What effect do black holes have on space-time?
A: The denser matter becomes, the more space-time warps until it creates a hole in space-time that is infinitely deep.
