Thank goodness for Hawking, the world has evidence that intelligence does exist on this planet.
Live Science: 8 Shocking Things We Learned From Stephen Hawking's Book
3. Theory of everything
If there is any "theory of everything" that can describe the whole universe, it is M theory, according to Hawking and Mlodinow. This model is a version of string theory, which posits that at the tiniest levels all particles are fundamentally little loops of string that vibrate at different frequencies. And, if true, all matter and energy would follow rules derived from the nature of these strings.
"M theory is the only model that has all the properties we think the final theory ought to have," the authors write.
One consequence of this theory is that our universe is not the only one – untold numbers of cousin universes exist with different physical laws and properties.
8. The universe is its own creator
One of the most talked-about assertions in the whole book is that we don't need the idea of God to explain what sparked the creation of the universe.
"It is not necessary to invoke God to light the blue touch paper and set the universe going," Hawking and Mlodinow write.
