Big space journey

The basis of this book was the course of Princeton University, which was read by the humanities of three famous astrophysicists - Neil Degrass Tyson, Michael Strauss and John Richard Gott. They talk about what they love the most, and tell you so that the most difficult theories become clear to non -specialists. Astronomers are not used to complicating what can be simple. Big red stars are red giants. Small white stars are white dwarfs. If the star pulsates, it is called pulsar. Even the beginning of the entire space, time, matter and energy that exist in space can be called only two simple words: Big explosion. What do we know about the universe? Our universe is great. Our space is much more than it seems. He is hotter than you think. Denser than you think. More rarely than you think. Whatever you think about the universe, reality will still be more incredible. Welcome to the Universe!
