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.
Scientists surely have a special responsibility. It is their ideas that form the basis of new technology. They should not be indifferent to the fruits of their ideas. They should forgo experiments that are risky or unethical.
I give infinite thanks to God, who has been pleased to make me the first observer of marvelous things.
We have at most ten years - not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions... We are near a tipping point, a point of no return, beyond which the built in momentum and feedbacks will carry us to levels of climate change with staggering consequences for humanity and all of the residents of this planet.
Surgery is the red flower that blooms among the leaves and thorns that are the rest of medicine.
It is remarkable, Hardin, how the religion of science has grabbed hold.
At the simplest level, economics can better show us the consequences of our actions. Less simple are cases in which we don't have the knowledge to predict the full consequences. Global warming and climate change are examples.
