“Space and time emerge from the laws rather than providing an arena in which things happen.” — Lee Smolin Copy Share Image
“Basically, string theory is the development of this visionary idea in a context of a fixed background of space and time. Loop… — Lee Smolin Copy Share Image
“Thus, the double unification given by the equivalence principle becomes a triple unification: All motions are equivalent once the effects of gravity… — Lee Smolin Copy Share Image
“Noncommutative geometry has turned up in several approaches to quantum gravity, including string theory, DSR, and loop quantum gravity. But none of… — Lee Smolin Copy Share Image
“Both loop quantum gravity and string theory assert that there is an atomic structure to space. In the next two chapters we… — Lee Smolin Copy Share Image
“The search for the meaning of temperature and entropy of matter led to the discovery of atoms. The search for the meaning… — Lee Smolin Copy Share Image
“Albert Einstein was certainly the most important physicist of the twentieth century. Perhaps his greatest work was his discovery of general relativity,… — Lee Smolin Copy Share Image
A successful unification of quantum theory and relativity would necessarily be a theory of the universe as a whole. It would tell… — Lee Smolin Copy Share Image
“The mind calls out for a third theory to unify all of physics, and for a simple reason. Nature is in an… — Lee Smolin Copy Share Image
“Similarly, a law of physics that allows information to be converted into geometry, and vice versa, but gives no account of why,… — Lee Smolin Copy Share Image
“This tells us that M theory, if it exists, cannot describe a world in which space os continuous and one can pack… — Lee Smolin Copy Share Image
“This unification of forces and motion has a simple consequence. In a particle theory, you can freely add all kinds of forces, so there… — Lee Smolin Copy Share
“One field Faraday studied was the electric field. This is not a number but a vector, which we may visualize as an arrow and… — Lee Smolin Copy Share
“It is interesting to note that the quantum-mechanical revolution was made by a virtually orphaned generation of scientists. Many members of the generation above… — Lee Smolin Copy Share
“In fact, the particle-antiparticle annihilation and the closing of the string is necessary, if the theory is to be consistent with relativity, meaning the… — Lee Smolin Copy Share
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… — Lee Smolin Copy Share
“Unfortunately, no one has ever successfully postulated a super-symmetry holding between two known particles. Instead, in all the supersymmetric theories the numbers of particles… — Lee Smolin Copy Share
Those who do good science do so because they choose problems that are suited to them. — Lee Smolin Copy Share
“Here's a simplified version of what the Stanford group did. They started with a much-studied kind of string theory-a flat four-dimensional spacetime with a… — Lee Smolin Copy Share
“The current crisis in particle physics springs from the fact that the theories have gone beyond the standard model in the last thirty years… — Lee Smolin Copy Share
“By the time I began my study of physics in the early 1970s, the idea of unifying gravity with the other forces was as… — Lee Smolin Copy Share
“These two discoveries, of relativity and of the quantum, each required us to break definitively with Newtonian physics. However, in spite of great progress… — Lee Smolin Copy Share
“So the challenge for any quantum theory of gravity is to give us a deeper understanding of Bekenstein's entropy and Hawking's temperature.” — Lee Smolin Copy Share
“Problem 1: Combine general relativity and quantum theory into a single theory that can claim to be the complete theory of nature. This is… — Lee Smolin Copy Share
“The loop approach to quantum gravity is now a thriving field of research. Many of the older ideas, such as supergravity and the study… — Lee Smolin Copy Share
“During the life of a black hole, it will pull in huge amounts of matter, carrying huge amounts of intrinsic information. At the end,… — Lee Smolin Copy Share
