“Each being in the universe yearns for the free energy necessary for survival and development. Each existence resists extinction. The consequent history of violence in the universe is as inevitable as the gravitational pull between the Earth and the Sun.”

“The earth was once molten rock and now sings operas.”

“It is said that there is nothing firm, nothing balanced, nothing durable in all the universe -- that nothing remains in its original state, that each day, each hour, each moment, there is change.”

“Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.”

“Look inside yourself and you can see the universe.”

“The universe is our picture. Only the immature imagine the cosmos to be what they think it is.”

“...things are the way they are in our universe because if they weren't, we wouldn't be here to notice.”
