Carl Sagan was an American Cosmologist, Astronomer, Planetary Scientist, author, and science communicator. He wrote books on the planetary system and produced a TV series called Cosmos – A Personal Voyage in which he presented a series. Later Neil deGrasse Tyson continued the series and called it Cosmos: A Spacetime Odyssey (2014).

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

Carl Sagan

Carl Sagan believes the meaning of life is up to us. We live in a vast and awesome universe in which, daily, suns are made and worlds destroyed, where humanity clings to an obscure clod of rock. The significance of our lives and our fragile realm derives from our wisdom and courage. He further says some 5 billion years from now, after it’s burned to a crisp, or even swallowed by the sun. There will be other worlds and stars and galaxies coming into being and they will know nothing of a place once called EARTH.

“Science is not only compatible with spirituality; it is a profound source of spirituality.”

Carl Sagan

The idea of the sense of self-worth comes not from anything we have done, not from anything worthy, but by an accident of birth of humiliation. The purpose is on us and we have to define it by staying humble to everyone, making equal rights for everyone, no discrimination, gender equality.

“Imagination will often carry us to worlds that never were, but without it we go nowhere.”

On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor, and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.

“Somewhere, something incredible is waiting to be known.”

Carl Sagan

Having said that, If we keep our purpose small such as to be kind and humble to everyone, helping each other would make a significant difference. Don’t pursue big goals just keep it simple and be conscious of yourself.

“If we crave some cosmic purpose, then let us find ourselves a worthy goal.”

Carl Sagan

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”
