If you have somebody who's brilliant and highly creative with a different point of view than you have, and a very different intellectual background, great things can happen.
Kip ThorneRead
If you go down through the horizon of a black hole, at the center you don't find a tunnel that leads you to some other place in the universe.
Interpretation
The quote suggests that a black hole doesn't connect to other parts of the universe like a tunnel, but rather is a unique singularity.
Kip Thorne's quote elucidates the complex nature of black holes in astrophysics, emphasizing that contrary to popular science fiction beliefs, falling into a black hole does not transport one to another part of the universe. Instead, it leads to a singularity where the laws of physics as we understand them cease to apply, highlighting the profound mysteries that black holes represent in our understanding of the cosmos.
In practice
In a lecture about black holes, you might quote Thorne to emphasize their unfamiliar nature.

I think that the future of the human race is to spread through the universe, and now is the time that we should be laying the foundations for that.
Whether you can go back in time is held in the grip of the law of quantum gravity.
'Closed timelike curve' is the jargon for time travel. It means you go out, come back and meet yourself in the past.
If you think that the distance from the Earth to the nearest planet where we could live comfortably... is being, like, from New York to Australia... what we've achieved so far, in going to the moon, that's about two-and-a-half inches. So that's the challenge.
A big misconception is that a black hole is made of matter that has just been compacted to a very small size. That's not true. A black hole is made from warped space and time.
The invention of the scientific method and science is, I'm sure we'll all agree, the most powerful intellectual idea, the most powerful framework for thinking and investigating and understanding and challenging the world around us that there is, and it rests on the premise that any idea is there to be attacked. If it withstands the attack then it lives to fight another day and if it doesn't withstand the attack then down it goes. Religion doesn't seem to work like that.
Biology occupies a position among the sciences at once marginal and central. Marginal because-the living world constituting but a tiny and very "special" part of the universe-it does not seem likely that the study of living beings will ever uncover general laws applicable outside the biosphere. But if the ultimate aim of the whole of science is indeed, as I believe, to clarify man's relationship to the universe, then biology must be accorded a central position . . .
If a given scientist had not made a given discovery, someone else would have done so a little later. Johann Mendel dies unknown after having discovered the laws of heredity: thirty-five years later, three men rediscover them. But the book that is not written will never be written. The premature death of a great scientist delays humanity; that of a great writer deprives it.
We were staring at the origin of a piece of our own bodies inside this 375-million-year-old fish. We had a fish with a wrist.
In experimental philosophy, propositions gathered from phenomena by induction should be considered either exactly or very nearly true notwithstanding any contrary hypotheses, until yet other phenomena make such propositions either more exact or liable to exceptions.
All of my life, I have been fascinated by the big questions that face us, and have tried to find scientific answers to them. If, like me, you have looked at the stars, and tried to make sense of what you see, you too have started to wonder what makes the universe exist.
