Systematic endeavour to gain knowledge Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe.[1][2] Modern science is typically divided into two or three major branches:[3] the natural sciences (e.g., physics, chemistry, and biology), which study the physical world; and the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies.[4][5] Applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine.[6][7][8] While sometimes referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science (which study formal systems governed by axioms and rules)[9][10] are typically regarded as separate because they rely on deductive reasoning instead of the scientific method or empirical evidence as their main methodology.[11][12][13][14] Etymology History Early history Middle Ages Awards.

There are only two events in the universe that defy the laws of physics: black holes and the big bang, and while scientists try to explain them, crucial evidence may be eaten up in the meantime.
Christophe Galfard's book is "The Universe in Your Hand A Journey Through Space, Time, and Beyond" ( Read more at BigThink.com: Follow Big Think here:YouTube: Transcript - The interesting thing about trying to unravel the laws of nature is that yes, we have found some laws. We understand gravity to some extent. We understand the quantum world with some extent. But we don’t understand everything. For a long time gravity has told us that nothing can escape the gravitational grip of a black hole.
And everything we had known about black holes until the mid-1970s was only related to gravity.
