A Quote by Kip Thorne

Whether you can go back in time is held in the grip of the law of quantum gravity. We are several decades away from a definitive understanding, 20 or 30 years, but it could be sooner than that.
Whether you can go back in time is held in the grip of the law of quantum gravity.
We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.
America is much less violent than it was 20, 30 years ago, and immigration is much less a problem than it was not just 20, 30 years ago, but when I came in as president.
When I go into my living room and turn on the TV, I feel like I have gone backwards in time by 20 to 30 years. It's an area of intense interest. I can't say more than that.
We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.
Science probes; it does not prove. Imagine Newton's reaction to an objector of his law of gravity who argued that he could not establish a universal law because he had not observed every falling apple, much less proved the law of gravity - there might, after all, be an apple that levitates! Why should a group of simple, stable compounds of carbon, hydrogen, oxygen and nitrogen struggle for billions of years to organize themselves into a professor of chemistry?
Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism - all together in one package, but only if the universe has more dimensions than the ones that we see.
I think baseball has such a way of humbling you. You can go 20-for-20, and before you know it, you're going to go through an 0-for-30. It has that way of knocking you back down to earth.
Americans now know that housing prices can go down and they can go down by 10, 20, 30, and in some cases, 40 or 50 percent. We know they can go down. But five years ago, we thought they could only go up.
When I go away, I do like to sunbathe and relax in the sun but I use SPF. I use factor 30 on my face and 20 or 30 on my body.
No one would have known, from how he held my hand, [that] over the years of heartache he had hatched a plot to change my life forever. He held his grip and would not let me go. I do not know what joins the parts of an atom, but it seems what binds one human to another is pain.
We have made a huge amount of progress over the last 50 years by enabling trade, by enabling kind of collaboration and learning. And actually, in fact, when you look at your average 30-year-old today, they're much better off than a 30-year-old 20 years ago, 30 years ago, because of progress in technology and health care and all the rest of this.
It's actually kind of weird that we can comprehend the law of gravity, or that we can understand quantum mechanics, enough at least to make computers.
Fifteen years of skepticism has done more for me than 20 years of force-fed religion and 30 years of indifference in between.
Relativity. Gravity. Quantum. Electrodynamics. Evolution. Each of these theories is true, whether or not you believe in them.
I could go through a lot of my old emails from when I first started doing comics. Back then the lowest age of fans was like 15 or 16 up to people in their 20's and 30's.
