The Big Bang Theory: An Expanding Universe
In The Big Bang Theory: An Expanding Universe, narrator Kate Yule explains how Einstein's equations have been used by other scientists to explain the structure and history of the Universe. Hakeem Oluseyi from the Florida Institute of Technology explains how some scientists think the Universe began with a Big Bang and has continued expanding. 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 happened to Einstein’s theory after he created it?
A: Other people started exploring it, and they used it not only to learn about the structure of the Universe, but also about its history.
Q: What would it mean if all the mass in the Universe was uniformly distributed?
A: It would mean that all the material was spread evenly.
Q: What was Georges Lemaître able to conclude from Einstein’s equations?
A: He was able to conclude that the Universe was either expanding or contracting.
