Interstellar Matter Quotes

The most remarkable discovery in all of astronomy is that the stars are made of atoms of the same kind as those on the earth.

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

In the physical universe, there are objects that include suns, planets, all life, and all matter in all dimensions. And then there is the space where all these things exist. That space is the vital element. For virtually every kid since 1968 who picked up a guitar to find his voice on the instrument, Jimmy Page has been the space that enables all our notes to be played.

"I think I know the real reason." "Which is?" "Alcohol in the dust clouds. Goddamn stuff is everywhere. Any lousy species ever invents the telescope and the spectroscope and starts looking in between the stars, what do they find?" He knocked the glass on the table. "Loads of stuff, but much of it alcohol." He drank from the glass. "Humanoids are the galaxy's way of trying to get rid of all that alcohol."

But one of the coolest things about meteorites is that most were formed four-and-a-half-billion years ago, during the birth of our solar system, when, for reasons not yet known, a cloud of gas and dust was transformed into a sun with circling planets.

We are made of stellar ash. Our origin and evolution have been tied to distant cosmic events. The exploration of the cosmos is a voyage of self-discovery.

All the stars that never were are parking cars and pumping gas.

We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star. We are the laws of chemistry and physics as they have played out here on Earth and we are now learning that planets are as common as stars. Most stars, as it turns out now, will have planets.

a handful of crumpled stars

I tell my students, with a feeling of pride that I hope they will share, that the carbon, nitrogen, and oxygen that make up ninety-nine per cent of our living substance were cooked in the deep interiors of earlier generations of dying stars. Gathered up from the ends of the universe, over billions of years, eventually they came to form, in part, the substance of our sun, its planets, and ourselves. Three billion years ago, life arose upon the earth. It is the only life in the solar system.

All the normal matter in the Milky Way disc is denser than the dark matter that surrounds it.

Every atom in your body came from a star that exploded. And the atoms in your left hand probably came from a different star than your right hand. It really is the most poetic thing I know about physics: you are all stardust.
