Carl Sagan Quotes

We are 'nuclear waste' from the fuel that makes stars shine; indeed, each of us contains atoms whose provenance can be traced back to thousands of different stars spread through our Milky Way.

The objects that are of moderate energy, like our sun or most of the stars that we see in the night sky with the naked eye, are objects in which relatively moderate energy processes are taking place.

I really have become convinced that nuclear fusion is our energy future. It's so powerful. I mean, it is the power of the stars. If we could bring that down to the laboratory and to the power plant on Earth, that would be an incredible thing.

A star is drawing on some vast reservoir of energy by means unknown to us. This reservoir can scarcely be other than the subatomic energy which, it is known exists abundantly in all matter; we sometimes dream that man will one day learn how to release it and use it for his service. The store is well nigh inexhaustible, if only it could be tapped. There is sufficient in the Sun to maintain its output of heat for 15 billion years.

Atoms are a relationship of energy. You are a relationship of energy interacting with another person who is another complex relationship of energy. We all exchange more than words with each other. . . We are made of the same substance as rocks and stars. .. We are an exotic cocktail living on this planet. .. We live in this universe which is a self-transcending reality

When we look up at night and view the stars, everything we see is shinning because of distant nuclear fusion.

There are as many atoms in one molecule of DNA as there are stars in a typical galaxy.

Stars burn clear all night till dawn. Do that yourself, and a spring will rise in the dark with water your deepest thirst is for.

Energy is the only universal currency: one of its many forms must be transformed to another in order for stars to shine, planets to rotate, plants to grow, and civilizations to evolve.

What, then, is this blue sky, which certainly does exist, and which veils from us the stars during the day?

Given the billions of neurons, this means there are as many connections in a single cubic centimeter of brain tissue as there are stars in the Milky Way galaxy.

The helium which we handle must have been put together at some time and some place. We do not argue with the critic who urges that the stars are not hot enough for this process; we tell him to go and find a hotter place.

God is able to place stars in their sockets & suspend sky like a curtain; surely He is mighty enough to light your path.

What is possible in the Cavendish Laboratory may not be too difficult in the sun.

Stars are holes in the sky, they are the light of Heaven coming from the other side.

Were a star quenched on high,For ages would its light,Still travelling downward from the sky,Shine on our mortal sight. So when a great man dies,For years beyond our ken,The light he leaves behind him liesUpon the paths of men.

Once, I asked my mom why stars shine. She said they were night-lights, so the angels could find their way around in Heaven. But when I asked my dad, he started talking about gas, and somehow I put it all together and figured that the food God served caused multiple trips to the bathroom in the middle of the night.

The star shines for everyone in the world, but in reality, it itself is surrounded in darkness.

Outside the sky is light with stars

We're physically part of the sun. The sun gives us energy, creates our world.

Iron is the final peal of a star’s natural life.

What is it that you contain? The dead. Time. Light patterns of millennia opening in your gut. Every minute, in each of you, a few million potassium atoms succumb to radioactive decay. The energy that powers these tiny atomic events has been locked inside potassium atoms ever since a star-sized bomb exploded nothing into being. Potassium, like uranium and radium, is a long-lived radioactive nuclear waste of the supernova bang that accounts for you. Your first parent was a star.

There are dead stars that still shine because their light is trapped in time. Where do I stand in this light, which does not strictly exist? (155)

We are the star and the darkness it peirces

What is it that you contain? The Dead. Time. Light patterns of millennia. The expanding universe opening in your gut. Are your twenty-three feet of intestines loaded with stars?
