This book will take you on a journey across the dimensions of time and space, and sometimes you will find yourself on the verge of a horizon.

The event of a black hole, where time has stopped, allows us to understand the mechanism of these wondrous objects. Another time, we will be at the gates of Alexandria, Baghdad, and Khwarazm, to objectively learn about the Muslim legacy of building experimental science, after they inherited it from the Greeks and before handing it over to Europe. During the same journey, we will pass by the factories of life, and observe how materials are built at the heart of stars. We will also learn about the thinking tools and scientific methods that helped us understand all these facts without having to travel beyond Earth, by analyzing and harnessing nature for the benefit of humanity.
Because this type of journey requires rockets and spacecraft, you'll find your wealth of knowledge and important information about the origins of rocketry in stories and a journey spanning from ancient China to Nazi Germany, before brain drain to the United States and a frantic race with the Soviet Union toward the moon, competing in space missions and programs.
