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.

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.
We're at a point in history were we have to become a part of the neighborhood of inhabited planets, like a neighborhood of a community, which we have not even acknowledged that that community exists up until this point.
In the good old days physicists repeated each other's experiments, just to be sure. Today they stick to FORTRAN, so that they can share each other's programs, bugs included.
When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?
Even if not a single fossil has ever been found, the evidence from surviving animals would still overwhelmingly force the conclusion that Darwin was right.
The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.
Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.
