Felipe Rivera Torres ，

This is a great book。I love how real science can come so close to science fiction and how passionate these guys are about these things。 I was never really good in school and never really paid attention to these subjects but somehow at 30 im really drawn to learn about them。 Probably will pick up the extended version soon。

I have never been a good student of science because all of the concepts seemed too advanced for me to comprehend。 The components of the universe are seemingly endless， but the three astrophysicists do a good job of making the composition easy to understand。 The two most abundant elements in the universe are hydrogen and helium。 Stars are made up of hydrogen and helium。 I might sound ignorant， but I did not know that stars generated heat。 I have a new respect for stars， upon learning this。 This b I have never been a good student of science because all of the concepts seemed too advanced for me to comprehend。 The components of the universe are seemingly endless， but the three astrophysicists do a good job of making the composition easy to understand。 The two most abundant elements in the universe are hydrogen and helium。 Stars are made up of hydrogen and helium。 I might sound ignorant， but I did not know that stars generated heat。 I have a new respect for stars， upon learning this。 This book motivates me to want learn what else contains hydrogen and helium in the universe。The universe is also composed of substances called dark energy and dark matter。 Dark energy is a vacuum like force that contains positive energy and negative pressure。 Dark energy is the force is that causes the universe to expand。 Dark matter are particles with a gravitational force that sucks in everything I also learned that there are moons on Jupiter and Saturn。 These moons are called Europa and Enceladus。 respectively。 All the insights in this book are fascinating to learn。 I have a greater appreciation for science because of this book。 。。。more
