Why is the Universe Flat | Lecture 3: "Big Challenges for Science" Series

It was once a big puzzle: why is the universe not curved but almost flat? In Einstein’s times this question did not have an answer but now we know why.
Third lecture of "Big Challenges for Science" Series by Dr. Pervez Hoodbhoy.

    The very day we started seeing more than 1M likes of these kind of science videos from a liberal and secular great person like Dr Pervez, will be the day Pakistan will become a great nation.

    Why is the universe flat? The answer can be found with the help of : 1-Euclidian geometry and Reimanian geometry 2-Theory of General relativity and Hubble's laws 3-Inflation theory 4-Cosmic background radiations
