The only thing I know is that we came from the stars, and that we have the same material as the stars. That's all that I know. Everything else I don't know.

Classifying the stars has helped materially in all studies of the structure of the universe.

The most wonderful discovery made by scientists is science itself.

It has been discovered that all the world is made of the same atoms, that the stars are of the same stuff as ourselves. It then becomes a question of where our stuff came from. Not just where did life come from, or where did the earth come from, but where did the stuff of life and of the earth come from?

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.

There are many unidentified bands in the spectra of stars. Wide bands are produced by some complex molecules in the interstellar space.

During the 20th century, we came to understand that the essence of all substances - their colour, texture, hardness and so forth - is set by their structure, on scales far smaller even than a microscope can see. Everything on Earth is made of atoms, which are, especially in living things, combined together in intricate molecular assemblages.

Big Bang gave us hydrogen and helium. We couldn't make people out of hydrogen and helium. So we're made out of exploding stars.

We are all made up of stars and all of us are billions of years old - that's what I believe, at least.

Indeed, our everyday world presents intellectual challenges just as daunting as those of the cosmos and the quantum, and that is where 99 per cent of scientists focus their efforts. Even the smallest insect, with its intricate structure, is far more complex than either an atom or a star.
