The difference between physics and metaphysics is not that the practitioners of one are smarter than the practitioners of the other. The difference is that the metaphysicist has no laboratory.
Imagination will often carry us to worlds that never were. But without it we go nowhere.
The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos.
We live in a vast and awesome universe in which, daily, suns are made and worlds destroyed, where humanity clings to an obscure clod of rock.
The Earth is a very small stage in a vast cosmic arena.
Our posturings, our imagined self-importance , the delusion that we have some privileged position in the universe are challenged by this point of pale light.

Before we devised artificial lights and atmospheric pollution and modern forms of nocturnal entertainment we watched the stars.

The brain is like a muscle. When it is in use we feel very good. Understanding is joyous.
I believe that the extraordinary should be pursued. But extraordinary claims require extraordinary evidence.
Organic as a dandelion seed, [the ship of our imagination] will carry us to worlds of dreams and worlds of facts
