“The current crisis in particle physics springs from the fact that the theories have gone beyond the standard model in the last thirty years fall into two categories. Some were falsifiable, and they were falsified. The rest are untested-either because… — Lee Smolin Copy Share Image
“Over the last three decades, theorists have proposed at least a dozen new approaches. Each approach is motivated by a compelling hypothesis, but none has so far succeeded. In the realm of particle physics, these include Technicolor, preon models, and… — 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 Image
“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 Image
“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 Image
“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 Image
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 Image
“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 Image
Those who do good science do so because they choose problems that are suited to them. — Lee Smolin Copy Share Image
“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 Image
“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 Image
“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 Image
“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 Image
“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 Image
