Where is loop quantum gravity going? I am sure you few have left most in the
dark.
dark.

Almost as spegetified as string theory.

wolram said:What is much more explosive and unpredictable is the collision or merger between LQG and Loll's "triangulations" approach. this is even slightly scary to me.
i have tried to follow this, but having just grasped some inkling of what
spinfoams are, the math seems to take a quantum leap in some other
direction, and left me, and I am sure others gasping for breath.
Loop Quantum Gravity is a theoretical framework that attempts to reconcile the theories of general relativity and quantum mechanics. It proposes that space and time are quantized, meaning they are made up of discrete units rather than being continuous. In LQG, the fabric of spacetime is seen as a network of interconnected loops, rather than a smooth continuum.
One of the main differences between LQG and other theories is its use of a discrete, or "quantized" spacetime. This sets it apart from string theory, for example, which posits that particles are made up of tiny vibrating strings. Additionally, LQG does not require the existence of extra dimensions, unlike some other theories.
One of the biggest challenges facing LQG is the lack of experimental evidence to support its predictions. As a theoretical framework, it has not yet been proven through empirical data. Additionally, there are still many open questions and areas of disagreement within the LQG community.
There are currently many ongoing research projects and collaborations focused on further developing and refining LQG. Some researchers are also exploring potential connections between LQG and other areas of physics, such as cosmology and black hole physics. Ultimately, the goal is to continue testing and expanding the theory to better understand the fundamental nature of spacetime.
If LQG is proven to be a valid theory, it could have a significant impact on our understanding of the universe. It could help explain some of the most fundamental questions in physics, such as the nature of time and the origin of the universe. Additionally, it could potentially help bridge the gap between general relativity and quantum mechanics, providing a more complete understanding of the laws that govern our universe.
