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.
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.
If you wish to make an apple pie from scratch, you must first invent the universe.
Imagination will often carry us to worlds that never were. But without it we go nowhere.
Who is more humble? The scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us, or somebody who says everything in this book must be considered the literal truth and never mind the fallibility of all the human beings involved?
For small creatures such as we the vastness is bearable only through love.
It pays to keep an open mind, but not so open your brains fall out.
We can judge our progress by the courage of our questions and the depth of our answers, our willingness to embrace what is true rather than what feels good.
The universe is a pretty big place. If it’s just us, seems like an awful waste of space.
