Sample Book Insights:

#1 The birth of the Universe was not until 10-43 seconds after the birth of the Universe, when gravity evolved. The first atoms were created about 300,000 years later, with the average temperature now only 3,000 degrees.

#2 The passage of time is exponential. It inherently moves in an exponential fashion, either geometrically gaining in speed or, as in the history of our Universe, geometrically slowing down.

#3 Time is relative to the entities experiencing it. For example, a man who travels at close to the speed of light to a star will return home after only a short period of time for him, but for his wife it will take forty years.

#4 The second law of thermodynamics, which states that disorder increases in a closed system, implies that the natural emergence of intelligence is impossible. However, the order of life takes place amid great chaos, and the existence of life-forms does not appreciably affect the measure of entropy in the larger system.
