“We have never observed infinity in nature. Whenever you have infinitie...” — Janna Levin Quote

“We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.”

“Ambiguity is very interesting in writing; it's not very interesting in science.”

“Now, our Sun will not collapse to a black hole. It's actually not massive enough.”

“For greed all nature is too little.”

“As pessimistic as I am about the nature of human beings and our capacity for atrocity and malevolence and betrayal and laziness and inertia, and all those things, I think we can transcend all that and set things straight.”

“I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul... we're required to do these things just as salmon swim upstream.”
