Quote by Carl Sagan

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

"The cosmos is a vast living body, of which we are still parts."

"Science is a way of thinking much more than it is a body of knowledge."

"For small creatures such as we, the vastness is bearable only through love."

"The best part of living is knowing you survived."

"The world needs heroes."

"Life is too short to live poorly."

"I'd rather be an optimist and be wrong than a pessimist and be right"
