Quantum Mechanics: String vs. Loop Theory

Click For Summary
SUMMARY

The discussion centers on the comparison between string theory and loop quantum gravity in the context of black holes and information escape. String theory posits that fundamental particles are one-dimensional strings, while loop quantum gravity suggests that spacetime itself is quantized. The conversation highlights the recent acceptance by Stephen Hawking that information can escape black holes, a significant shift in theoretical physics. Understanding these theories is crucial for grasping modern interpretations of quantum mechanics.

Well no replies there, so much for trying to learn about quantum mechanics? Ok a different question, there are two theories I've heard about black holes and the reason why Hawking has now accepted that information can escape from black holes, one is string theory, the other is loop theory, string theory I know about but what is this loop quantum gravity theory and how does it differ from strings?
