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.

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.
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.
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.
If there is no solace in the fruits of our research, there is at least some consolation in the research itself. Men and women are not content to comfort themselves with tales of gods and giants, or to confine their thoughts to the daily affairs of life; they also build telescopes and satellites and accelerators and sit at their desks for endless hours working out the meaning of the data they gather.
In summoning even the wisest of physicians to our aid, it is probably that he is relying upon a scientific "truth", the error of which will become obvious in just a few years' time.
Therefore in medicine we ought to know the causes of sickness and health.
Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.
Cancer is like the common cold; there are so many different types. In the future we'll still have cancer, but we'll detect it very, very early, so that it won't kill anybody. We'll zap it at the molecular level decades before it grows into a tumor.
Although the theory of relativity makes the greatest of demands on the ability for abstract thought, still it fulfills the traditional requirements of science insofar as it permits a division of the world into subject and object (observer and observed) and, hence, a clear formulation of the law of causality.
