...things are the way they are in our universe because if they weren't, we wouldn't be here to notice. — Brian Greene Copy Share Image
The bottom line is that time travel is allowed by the laws of physics. — Brian Greene Copy Share Image
A unified theory would put us at the doorstep of a vast universe of things that we could finally explore with precision. — Brian Greene Copy Share Image
...quantum mechanics—the physics of our world—requires that you hold such pedestrian complaints in abeyance. — Brian Greene Copy Share Image
When I give this talk to a physics audience, I remove the quotes from my 'Theorem'. — Brian Greene Copy Share Image
All you are is a bag of particles acting out the laws of physics. That to me is pretty clear. — Brian Greene Copy Share Image
No matter how hard you try to teach your cat general relativity, you're going to fail. — Brian Greene Copy Share Image
Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine… — Brian Greene Copy Share Image
Even when I wasn't doing much 'science for the public' stuff, I found that four or five hours of intense work in… — Brian Greene Copy Share Image
Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can… — Brian Greene Copy Share Image
The math of quantum mechanics and the math of general relativity, when they confront one another, they are ferocious antagonists and the… — Brian Greene Copy Share Image
If string theory is right, the microscopic fabric of our universe is a richly intertwined multidimensional labyrinth within which the strings of… — Brian Greene Copy Share Image
Physics grapples with the largest questions the universe presents. 'Where did the totality of reality come from?' 'Did time have a beginning?' — Brian Greene Copy Share Image
Quantum mechanics broke the mold of the previous framework, classical mechanics, by establishing that the predictions of science are necessarily probabilistic. — Brian Greene Copy Share Image
You almost can't avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions… — Brian Greene Copy Share Image
The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory… — Brian Greene Copy Share Image
In quantum mechanics there is A causing B. The equations do not stand outside that usual paradigm of physics. The real issue… — Brian Greene Copy Share Image
That is, you can have nothingness, absolute nothingness for maybe a tiny fraction of a second, if a second can be defined… — Brian Greene Copy Share Image
String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of… — Brian Greene Copy Share Image
Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you… — Brian Greene Copy Share Image
“We all love a good story. We all love a tantalizing mystery. We all love the underdog pressing onward against seemingly insurmountable… — Brian Greene Copy Share Image
My view is that you don't tell the universe what to do. The universe is how it is, and it's our job… — Brian Greene Copy Share Image
Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the… — Brian Greene Copy Share Image
For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually… — Brian Greene Copy Share Image
When general relativity was first put forward in 1915, the math was very unfamiliar to most physicists. Now we teach general relativity… — Brian Greene Copy Share Image
Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent. — Brian Greene Copy Share Image
The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers. — Brian Greene Copy Share
The number of e-mails and letters that I get from choreographers, from sculptors, from composers who are being inspired by science is huge. — Brian Greene Copy Share
One of the wonders of science is that it is completely universal. It crosses national boundaries with total ease. — Brian Greene Copy Share
String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe… — Brian Greene Copy Share
But, as Einstein once said, “For we convinced physicists, the distinction between past, present, and future is only an illusion, however persistent.”5 — Brian Greene Copy Share
Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer. — Brian Greene Copy Share
When kids look up to great scientists the way they do to great musicians and actors, civilization will jump to the next level — Brian Greene Copy Share
I have long thought that anyone who does not regularly - or ever - gaze up and see the wonder and glory of a… — Brian Greene Copy Share
There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's… — Brian Greene Copy Share
As every parent knows, children begin life as uninhibited, unabashed explorers of the unknown. From the time we can walk and talk, we want… — Brian Greene Copy Share
The full name of string theory is really superstring theory. The 'super' stands for this feature called supersymmetry, which, without getting into any details,… — Brian Greene Copy Share
For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using… — Brian Greene Copy Share
Writing for the stage is different from writing for a book. You want to write in a way that an actor has material to… — Brian Greene Copy Share
We know that if supersymmetric particles exist, they must be very heavy; otherwise we would have spotted them by now. — Brian Greene Copy Share
The beauty of string theory is the metaphor kind of really comes very close to the reality. The strings of string theory are vibrating… — Brian Greene Copy Share
