Neutron Density

"To achieve this density of a neutron star at home, just cram a herd of 50 million elephants into the volume of a thimble. Everybody has a plan until they get hit. Then, like a rat, they stop in fear and freeze."

Greenhouse Effect

"If Earth ever suffers a runaway greenhouse effect (like what has happened on Venus), then our atmosphere would trap excess amounts of solar energy, the air temperature would rise, and the oceans would swiftly evaporate into the atmosphere as they sustained a rolling boil. I want to rip out his heart and feed it to Lennox Lewis. I want to kill people. I want to rip their stomachs out and eat their children."

Cosmic Perspective

"Those who see the cosmic perspective as a depressing outlook, they really need to reassess how they think about the world. Sometimes I put on a ski mask and dress in old clothes, go out on the streets and beg for quarters."

 

Molecules

"Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. I just have this thing inside me that wants to eat and conquer. Maybe it's egotistical, but I have it in me. I don't want to be a tycoon. I just want to conquer people and their souls."
