Somewhere, something incredible is waiting to be known.

We’re made of star stuff. We are a way for the cosmos to know itself.
If you want to make an apple pie from scratch, you must first create the universe.

For small creatures such as we the vastness is bearable only through love.
Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.

For me, it is far better to grasp the Universe as it really is than to persist in delusion, however satisfying and reassuring.
Imagination will often carry us to worlds that never were. But without it we go nowhere.

We live in a society exquisitely dependent on science and technology, in which hardly anyone knows anything about science and technology.

We are like butterflies who flutter for a day and think it is forever.

Science is a way of thinking much more than it is a body of knowledge.
