More and more science fiction movies are inspired by popular science in such sciences as Stars and Stars (2014). Also biographical scientists, such as Hawking's Theory of Everything (2014). Then Einstein's film in the television series Genius (2017) and finally a biopic about Neil A Armstrong in the first man (2018). These films show an increasing interest in science, in particular astronomy and cosmology.

However, attracting scholars often simply stops watching theaters. The community seems too busy to embrace the universe. They do not want to read thick science books or participate in scientific seminars. For this reason, American astrophysicist Neil deGrasse Tyson wrote this astrophysical book for busy people (2018). Tyson also devoted a book with a paragraph sentence: "For all those who are too busy to have time to read thick books. However, they are still looking for channels for the universe."

This book provides a basic insight into all the great ideas and discoveries that support the modern understanding of the universe. The author invites readers to briefly explore the cosmos, from the history of the Big Bang, to search for life in the universe.

He reveals the power and beauty of physics laws, because they are everywhere. The discovery of Newton from the law of the fall of the fallen apple weight, it turns out, applies also to planets, asteroids and comets around the sun (p. 13).

The book expresses the connection between gravity and height of mountains. The object of universes is round. The origin of the element's name in the periodic table is until scientists find the "invisible" light, such as infrared and ultraviolet rays. Tyson wrote it with a language full of empathy and amazement, but it was still fun because there was a lot of humor.

For example, when it comes to the discovery of invisible light, gamma rays. He wrote: "Anyone who watches too much science fiction knows that gamma rays are bad for humans. People can be green and muscular, or remove handhelds from their wrists" (p. 107).

This book also discusses another possibility of life outside the Earth. Exoplanets or planets are believed to be similar to Earth, first discovered in 1995. The amount found now amounts to three thousand. The universe is huge.

It is estimated that the Milky Way Galaxy alone has up to 40 billion Earth's planets. That is, said Tason, a planet that you might ever want to visit (page 131). It all sounds exotic and hard to believe. But was it not considered crazy when Copernicus proposed Earth around the Sun?

There are still a lot of unknowns. People just started to celebrate the universe. This book helps readers to understand so much interesting about astronomy and cosmology. This book is suitable for those who are too busy to understand the universe class, textbooks, or documentaries. An astrophysical book for busy people can be a fun and entertaining brief introduction.
