John N. Bahcall Quotes

These neutrino observations are so exciting and significant that I think we're about to see the birth of an entirely new branch of astronomy: neutrino astronomy. Supernova explosions that are invisible to us because of dust clouds may occur in our galaxy as often as once every 10 years, and neutrino bursts could give us a way to study them.

We should do astronomy because it is beautiful and because it is fun. We should do it because people want to know. We want to know our place in the universe and how things happen.

The most important discoveries will provide answers to questions that we do not yet know how to ask and will concern objects we have not yet imagined.

I do not personally want to believe that we already know the equations that determine the evolution and fate of the universe; it would make life too dull for me as a scientist. ... I hope, and believe, that the Space Telescope might make the Big Bang cosmology appear incorrect to future generations, perhaps somewhat analogous to the way that Galileo's telescope showed that the earth-centered, Ptolemaic system was inadequate.

Every time we get slapped down, we can say, Thank you Mother Nature, because it means we're about to learn something important.

In my personal view, a failure to discover unimagined objects and answer unasked questions, once HST functions properly, would indicate a lack of imagination in stocking the Universe on the part of the Deity.

Our Cosmic Habitat is certain to be widely quoted and widely read. It is beautifully written, using inspiring and stimulating analogies. While the book is intended for the nonscientist, it provides an accurate guide to the best current thinking about the nature and constitution of our universe. If I wanted to give a gift to a person I would like to become a close friend, this is the book I would choose.

I personally feel it is presumptuous to believe that man can determine the whole temporal structure of the universe, its evolution, development and ultimate fate from the first nanosecond of creation to the last 10^10 years, on the basis of three or four facts which are not very accurately known and are disputed among the experts.
