"Some molecules - ammonia, carbon dioxide, water - show up everywhere in the universe, whether life is present or not. But others pop up especially in the presence of life itself. Among the biomarkers in Earth's atmosphere are ozone-destroying chlorofluorocarbons from aerosol sprays, vapor from mineral solvents, escaped coolants from refrigerators and air conditioners, and smog from the burning of fossil fuels. No other way to read that list: sure signs of the absence of intelligence."

"Time in itself, absolutely, does not exist; it is always relative to some observer or some object. Without a clock I say 'I do not know the time' . Without matter time itself is unknowable. Time is a function of matter; and matter therefore is the clock that makes infinity real."
"I don't think there's an interesting boundary between philosophy and science. Science is totally beholden to philosophy. There are philosophical assumptions in science and there's no way to get around that."
"Much more plausible is the computer-based explanation that dreams are a spillover from the unconscious processing of the day's experience, from the brain's decision on how much of the daily events temporarily stored in a kind of buffer to emplace in long-term memory... The American psychiatrist Ernest Hartmann of Tufts University has providedanecdotal but reasonably persuasive evidence that people who are engaged in intellectual activities during the day, especially unfamiliar intellectual activities, require more sleep at night, while, by and large, those engaged in mainly repetitive and intellectually unchallenging tasks are able to do with much less sleep."
"Dark Energy is poorly understood and it is clear that we are currently moving into exploring thecomplete electromagnetic spectrum that also includes the study of atmospheric pressure waves,atmospheric voltage effects on the cellular system, and the biological effects of the various forms ofatmospheric radiation transmission."

"To learn that it's easier to be told by others what to think and believe than it is to think for yourself."
"I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up-many people feel small, because they're small and the Universe is big, but I feel big, because my atoms came from those stars."
"Let's say intelligence is your ability to compose poetry, symphonies, do art, math and science. Chimps can't do any of that, yet we share 99 percent DNA. Everything that we are, that distinguishes us from chimps, emerges from that one-percent difference."
"Some of the greatest poetry is revealing to the reader the beauty in something that was so simple you had taken it for granted."
"There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end."
"I'm perennially intrigued how people who lead largely evidence-based lives can, in a belief-based part of their mind, be certain that an invisible, divine entity created an entire universe just for us, or that the government is stockpiling space aliens in a secret desert location."
"We explore our environment, more than we are compelled to utter poetry, when we're toddlers. We start doing that later. Before that happens, every child is a scientist."
"I know that the molecules in my body are traceable to phenomena in the cosmos. That makes me want to grab people on the street and say: 'Have you HEARD THIS?"
"People cited violation of the First Amendment when a New Jersey schoolteacher asserted that evolution and the Big Bang are not scientific and that Noah's ark carried dinosaurs. This case is not about the need to separate church and state; it's about the need to separate ignorant, scientifically illiterate people from the ranks of teachers."
