A Brief History of Time

“The universe doesn't allow perfection.” 





“If time travel is possible, where are the tourists from the future?”




 “Ever since the dawn of civilization, people have not been content to see events as unconnected and inexplicable. They have craved an understanding of the underlying order in the world. Today we still yearn to know why we are here and where we came from. Humanity's deepest desire for knowledge is justification enough for our continuing quest. And our goal is nothing less than a complete description of the universe we live in.” 



“If there really is a complete unified theory that governs everything, it presumably also determines your actions. But it does so in a way that is impossible to calculate for an organism that is as complicated as a human being. The reason we say that humans have free will is because we can't predict what they will do.” 



“The increase of disorder or entropy is what distinguishes the past from the future, giving a direction to time.” 

Stephen Hawking
