Claiming there is no other life in the universe is like scooping up some water, looking at the cup and claiming there are no whales in the ocean.

Never presume that just because you disagree with an idea that you must be correct.

When I reach to the edge of the universe, I do so knowing that along some paths of cosmic discovery, there are times when, at least for now, one must be content to love the questions themselves.

It's quite literally true that we are star dust, in the highest exalted way one can use that phrase. ...I bask in the majesty of the cosmos. I use words, compose sentences that sound like the sentences I hear out of people that had revelation of Jesus, who go on their pilgrimages to Mecca.

I am convinced that the act of thinking logically cannot possibly be natural to the human mind. If it were, then mathematics would be everybody's easiest course at school and our species would not have taken several millennia to figure out the scientific method.

If you're scientifically literate, the world looks very different to you, and that understanding empowers you.

What are the lessons to be learned from this journey of the mind through the universe? That humans are emotionally fragile, perennially gullible, hopelessly ignorant masters of an insignificantly small speck in the cosmos. Have a nice day.
