I understand that it is a quantum take on space-time. I just don't actually understand IT. Can anyone help? Any good online lectures or explanations?
Thanks.
Thanks.

shoehorn said:In case you're interested in something a bit more substantial than online lectures you might find the following of help. Rovelli's book is a good read, dealing, as it does, with many of the basic topics. It should be noted, however, that it's philosophical in nature, and most certainly isn't a textbook. I also have severe disagreements with several points he raises in the book (indeed, he makes more than a few claims which are patently false)...

Loop Quantum Gravity is a theoretical framework that attempts to reconcile the principles 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.
Unlike other theories of quantum gravity, Loop Quantum Gravity does not require the existence of extra dimensions or the use of super-symmetry. It also does not rely on singularities or the concept of a "beginning" of the universe.
No, Loop Quantum Gravity is still a theoretical framework and has not yet been proven through experiments or observations. However, it is a promising approach to understanding the fundamental nature of space and time.
Yes, Loop Quantum Gravity proposes that the singularity in black holes is actually a "quantum bounce" where the matter that falls into the black hole is ejected back out in a new form, preventing the existence of a true singularity.
Yes, there are several free online lectures and resources available for learning about Loop Quantum Gravity. Some popular options include the free online course "Quantum Gravity: From Theory to Experimental Search" on Coursera and the YouTube channel "Loop Quantum Gravity by Carlo Rovelli".
