Here, we’ve compiled a list of the best String Theory Quotes from famous authors such as Ashoke Sen, Leonard Susskind, Lee Smolin, Paul Davies, Brian Greene. Let’s look at these pieces of wisdom. We definitely have something to learn from them!

1

The beauty of string theory is that it is all about mathematics. For that, you don’t need resources or labs. Just sit in your room and do the maths.

2

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.

3

If string theory is a mistake, it’s not a trivial mistake. It’s a deep mistake and therefore kind of worthy.

4

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.

5

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.

6

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.

7

Technically you need the extra dimensions. At first people didn’t like them too much, but they’ve got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions.

8

I came to realise that string theory offers us the best hope of finding a unified theory of all matter and forces.

9

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.

10

String theory is not the only theory that can accommodate extra dimensions, but it certainly is the one that really demands and requires it.

11

There are a lot of good things about string theory, and it’s great that some people want to work on it.

12

So when you ask me how string theory might be tested, I can tell you what’s likely to happen at accelerators or some parts of the theory that are likely to be tested.

13

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.

14

For bedtime reading, I usually curl up with a good monograph on quantum physics or string theory, my specialty. But since I was a child, I have been fascinated by science fiction. My all-time favorite is ‘The Foundation Trilogy,’ by Isaac Asimov.

15

My work on symmetries of string theory is on what is known as strong-weak coupling duality, or S-duality.

16

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

17

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you’ll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you’ll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

18

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.

19

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.

20

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.

21

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.

22

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.

23

I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics.

24

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.

25

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.

26

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.

27

Our best theory of describing space at a fundamental level is probably string theory.

28

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.

29

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.

30

I spent most of my career doing high-energy physics, quarks, dark matter, string theory and so on.
