Grand Unified Theory Quotes

There is nothing new to be discovered in physics now, All that remains is more and more precise measurement

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.

The best theory comes from string theory, which states that dark matter is nothing but a higher vibration of the string. We are, in some sense, the lowest octave of a vibrating string.

In many ways, string theory attempts to go beyond Einstein's dream... an all-encompassing description of nature that works at large distances where gravity becomes important as well as small distances where quantum mechanics is important.

One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.

M-theory is the unified theory Einstein was hoping to find.

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

Michio Kaku and Albert Einstein, they're both so ahead of our time. It's just fascinating to read about them, what their theories are on loopholes and everything else. It's fascinating stuff.

Some physicists solve that problem of the necessity of finely tuned physical constants ... by invoking the anthropic principle, saying, well, here we are, we exist, we have to be in the kind of universe capable of giving rise to us. That in itself is, I think, unsatisfying, and as John Lennox rightly says, some physicists solve that by the multiverse idea-the idea that our universe is just one of many universes.

Physics has entered a remarkable era. Ideas that were once the realm of science fiction are now entering our theoretical — and maybe even experimental — grasp. Brand-new theoretical discoveries about extra dimensions have irreversibly changed how particle physicists, astrophysicists, and cosmologists now think about the world. The sheer number and pace of discoveries tells us that we've most likely only scratched the surface of the wondrous possibilities that lie in store. Ideas have taken on a life of their own.

To a physicist life looks nothing short of a miracle. It's just amazing what living things can do.

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future.

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.

As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore.

I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for.

Some string theorists prefer to believe that string theory is too arcane to be understood by human beings, rather than consider the possibility that it might just be wrong.

In 1956, when I began doing theoretical physics, the study of elementary particles was like a patchwork quilt. Electrodynamics, weak interactions, and strong interactions were clearly separate disciplines, separately taught and separately studied. There was no coherent theory that described them all.

The present situation in physics is as if we know chess, but we don't know one or two rules.

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.

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 think the discovery of supersymmetric partners for the known particles would revolutionize our understanding of the universe.

The idea of an ordered and elegant universe is a lovely one. One worth clinging to. But you don't need religion to appreciate the ordered existence. It's not just an idea, it's reality. We're discovering the hidden orders of the universe every day.

I don't think about a theory of everything when I do my research. And even if we knew the ultimate underlying theory, how are you going to explain the fact that we're sitting here? Solving string theory won't tell us how humanity was born.

There is now a feeling that the pieces of physics are falling into place, not because of any single revolutionary idea or because of the efforts of any one physicist, but because of a flowering of many seeds of theory, most of them planted long ago.

We are not at the end but at the beginning of a new physics. But whatever we find, there will always be new horizons continually awaiting us.
