Who invented Lqg?

Carlo Rovelli
Carlo Rovelli, a physicist at the University of Marseille and a founding father of LQG, believes his field ascendant. “The string planet is infinitely less arrogant than ten years ago, especially after the bitter disappointment of the non-appearance of supersymmetric particles,” he said.

What is the loop theory?

Loop quantum gravity (LQG) is a theory of quantum gravity, which aims to merge quantum mechanics and general relativity, incorporating matter of the Standard Model into the framework established for the pure quantum gravity case. Consequently, not just matter, but space itself, prefers an atomic structure.

Who founded loop quantum gravity?

Roger Penrose: mathematical physicist who invented spin networks and twistor theory. Jorge Pullin: physicist who helped develop loop quantum gravity, co-author of Loops, Knots, Gauge Theories and Quantum Gravity. Carlo Rovelli: one of the founders and major contributors to loop quantum gravity.

What is the basic idea of loop quantum gravity?

Loop quantum gravity ( LQG) is a theory of quantum gravity, which aims to merge quantum mechanics and general relativity, incorporating matter of the Standard Model into the framework established for the pure quantum gravity case. As a candidate for quantum gravity, LQG competes with string theory.

What does ‘loop’ mean in loop quantum gravity?

Loop quantum gravity. According to Einstein, gravity is not a force – it is a property of spacetime itself. Loop quantum gravity is an attempt to develop a quantum theory of gravity based directly on Einstein’s geometric formulation.

What is quantum gravity in simple words?

In the simplest words, Quantum gravity is a theoretical framework that aims to describe how the force of gravity works for the universe’s smallest bits. Being a quantum theory of gravity, it seeks to describe gravity according to quantum mechanics principles, and in situations where quantum effects cannot be ignored, at the so-called Planck scale.

Is loop quantum gravity equivalent to string theory?

String theory and quantum loop gravity are two theories of quantum gravity . But they are two different approaches. String theory is a theoretical attempt to unify all four fundamental interactions. Loop quantum gravity doesn’t attempt to unify fundamental interactions. It is just a theory of quantum gravity.
