Was reading Baez's page and came across this link:

It's somewhat interesting, have a read.

LQG, or Loop Quantum Gravity, is a theory that attempts to reconcile Einstein's theory of General Relativity with the principles of quantum mechanics. It posits that space and time are made up of discrete units, or "loops", rather than being continuous as described by General Relativity. String Theory, on the other hand, attempts to unify all the fundamental forces of nature by describing them in terms of tiny, vibrating strings. While both theories aim to solve the same fundamental problems in physics, they approach it from different perspectives and have yet to be fully reconciled.
John Baez is a mathematical physicist who has made significant contributions to the field of LQG and String Theory. His page on the subject is highly regarded as a reliable source of information and updates on the latest developments in these theories. He also presents the material in a clear and accessible manner, making it a valuable resource for both scientists and non-scientists interested in these theories.
Currently, there is no direct evidence for either LQG or String Theory. Both theories are still in the realm of theoretical physics and have yet to be experimentally confirmed. However, there are ongoing efforts to test predictions of these theories through experiments such as the search for gravitational waves and the study of the cosmic microwave background radiation.
There have been attempts to combine LQG and String Theory into a single theory, known as String Field Theory. However, this is still a work in progress and has not yet been fully successful. Both theories are highly complex and have their own inherent difficulties, making it a challenging task to merge them into a single framework.
If LQG or String Theory, or a combination of both, is proven to be correct, it would have profound implications for our understanding of the fundamental laws of the universe. It would provide a unified description of all the forces of nature and potentially lead to a deeper understanding of concepts such as space, time, and gravity. It could also open up new possibilities for technology and advancements in fields such as quantum computing and space travel.
