Words matter. These are the best String Theory Quotes from famous people such as Brian Greene, Roy H. Williams, David Gross, Michio Kaku, Lee Smolin, and they’re great for sharing with your friends.
I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.
My emotional investment is in finding truth. If string theory is wrong, I’d like to have known that yesterday. But if we can show it today or tomorrow, fantastic.
Very much, string theory is simply a work in progress. What we are inching toward every day are predictions that within the realm of current technology we hope to test. It’s not like we’re working on a theory that is permanently beyond experiment. That would be philosophy.
I’d say many features of string theory don’t mesh with what we observe in everyday life.
Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.
In order to achieve a true understanding of string theory, some new idea will be required, and most likely, some break with the concepts on which we’ve traditionally based physical theory.
Time travel and teleportation will have to wait. It may take centuries to master these technology. But within the coming decades, we will understand dark matter, perhaps test string theory, find planets which can harbor life, and maybe have Brain 2.0, i.e. our consciousness on a disk which will survive even after we die.
Every string theory that’s been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased.
According to String Theory, what appears to be empty space is actually a tumultuous ocean of strings vibrating at the precise frequencies that create the 4 dimensions you and I call height, width, depth and time.
String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.
The most important single thing about string theory is that it’s a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That’s big news.
General relativity is the cornerstone of cosmology and astrophysics. It has also provided the conceptual basis for string theory and other attempts to unify all the forces of nature in terms of geometrical structures.
In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the ‘Mind of God’ is cosmic music resonating in 11-dimensional hyperspace.
Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.
I work in string theory. This is a branch of physics which assumes that the elementary objects in the universe are not particles but one-dimensional objects, that is, strings.
String theory is not the only theory that can accommodate extra dimensions, but it certainly is the one that really demands and requires it.
Is the universe ‘elegant,’ as Brian Greene tells us? Not as far as I can tell, not the usual laws of particle physics, anyway. I think I might find the universal principles of String Theory most elegant – if I only knew what they were.
One of the strangest features of string theory is that it requires more than the three spatial dimensions that we see directly in the world around us. That sounds like science fiction, but it is an indisputable outcome of the mathematics of string theory.
The full name of string theory is really superstring theory. The ‘super’ stands for this feature called supersymmetry, which, without getting into any details, predicts that for every known particle in the world, there should be a partner particle, the so-called supersymmetric partner.
I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics.
There are a lot of good things about string theory, and it’s great that some people want to work on it.
When we understand string theory, we will know how the universe began. It won’t have much effect on how we live, but it is important to understand where we come from and what we can expect to find as we explore.
String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner. I do believe the universe is consistent, and therefore I do believe that general relativity and quantum mechanics should be put together in a manner that makes sense.
We need a theory that goes before the Big Bang, and that’s String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.
My work on symmetries of string theory is on what is known as strong-weak coupling duality, or S-duality.
Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle. String theory does so again because a point particle is replaced by a string, which is more spread out.
Our best theory of describing space at a fundamental level is probably string theory.
I’ve been reading about the idea of cyclical lives – it matches up to the idea of string theory and a multiverse. So I wanted to write a record about that instead of another song about broken hearts and drinking.
When you look at the calculation, it’s amazing that every time you try to prove or disprove time travel, you’ve pushed Einstein’s theory to the very limits where quantum effects must dominate. That’s telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.
When I was in high school, I was really into string theory and superstring theory and read ‘Scientific American.’ It’s fascinating.
