In general, the larger the breeding population, the slower the rate of evolution.

You know; when I look at the night sky and I see this enormous splendor of stars and galaxies, I sometimes ask the question, well how many worlds are we talking about? Well do the math, there are about 100 billion galaxies that are in the visible universe and each galaxy in turn contains about 100 billion stars, you multiply and you get about ten billion trillion stars. Well I think it is the height of arrogance to believe that we are alone in the universe, my attitude is that the universe is teaming, teaming with different kinds of life forms

When we're born, we want to know why the stars shine. We want to know why the sun rises.

Think of all the nonsense you had to learn in psychology courses. None of which was testable. None of which was measurable. We had behaviorism, Freudian psychology, all of these theories that you learn in psychology. Totally untestable. Now, we can test it, because physics allows us to calculate energy flows in the brain.

Computer chips will cost about a penny. That's the cost of scrap paper. The Internet will be basically for free and it will be inside our contact lens. When we blink, we will go online. When we see somebody that we don't recognize, our contact lens will identify who they are, print out their biography in your contact lens and translate, if they're speaking Chinese, into English with subtitles as they speak.
