In Astrophysics for People in a Hurry, Neil deGrasse Tyson takes the reader on a voyage from the beginning of our universe and the big bang to our modern world and the ought to place our existence inside a wider cosmological perspective. Starting from the large bang, we learn how the expansion and cooling of our universe created the conditions for light to travel across the universe. This light, traveling over billions of years permits astrophysicists to check back in time and reconstruct the events since the creation of our universe. In this exploration of our cosmos, tyson introduces us to Newton’s law of gravity and Einstein’s theory of relativity theory. While these laws of physics are universal throughout the cosmos and facilitate us perceive the movement of the planets and stars, they additionally open us up to the deeper mysteries of our universe, like matter and dark energy. Although we tend to might understand our universe as huge and empty, Tyson explores the space between galaxies and planets in our own solar system, suggesting that what we find in between, is just as fascinating to check because the planets and also the stars.
