Astrophysics for People in a Hurry
Neil DeGrasse Tyson

Summary

A nice short read from Neil Degrasse Tyson that explains the most relevant concepts in astrophysics in a relatively digestable way

Rating: 3/5

Notes

The laws of physics are true, whether or not you believe in them

Comet cluster and Zumidy experiments show that galaxies are moving so fast that they shouldn’t be together and yet they are because of dark matter

Dark matter exists but doesn’t follow the rules of normal physics

Dark matter is 6 times as strong as normal gravity but also can’t see it

Your brain is a satchel of preconceived ideas, post-conceived notions and bias

Smallest surface for an enclosed volume is a sphere

More stars than words and sounds uttered by every human who ever lived
