My deeply held belief is that if a god of anything like the traditional sort exists, our curiosity and intelligence is provided by such a God. We would be unappreciative of that gift if we suppressed our passion to explore the universe and ourselves.

Carl Sagan

Carl Sagan

Nobody listens to mathematicians.

Carl Sagan

On the day that we do discover that we are not alone, our society may begin to evolve and transform in some incredible and wondrous new ways.
