There are no forbidden questions in science, no matters too... - Carl Sagan

"La prueba de ausencia no es prueba de ausencia"

"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself."

"The idea that God is an oversized white male with a flowing beard, who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by 'God,' one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying... it does not make much sense to pray to the law of gravity."

"Somewhere, something incredible is waiting to be known."

"If it can be destroyed by the truth, it deserves to be destroyed by the truth."
