Amazing bid by Thiemann to absorb string theory into LQG

In summary: Fock representation of current string theory and hence would not be generic.The solution presented in this paper exploits the flatness of the target space in several important ways. In a companion paper we treat the more complicated case of curved target spaces. Thiemann's conclusions paragraph suggests that combining canonical and algebraic methods may be fruitful in analyzing the string and its representations. He also mentions that the specific Fock representation used in string theory may not be the end of the story and that there may be simpler representations of the string, particularly in lower dimensions and possibly without supersymmetry, that could solve some of the current puzzles in string theory. This would demonstrate that the critical dimensions, supersymmetry, and matter content of the

Well, the Colosi-Rovelli paper doesn't contain the word polymer at least!

1. What is the "Amazing bid by Thiemann" in relation to string theory and LQG?

The "Amazing bid by Thiemann" refers to a proposal made by physicist Thomas Thiemann to incorporate elements of string theory into loop quantum gravity (LQG), a theory of quantum gravity that seeks to reconcile general relativity with quantum mechanics.

2. How does Thiemann's proposal attempt to reconcile string theory and LQG?

Thiemann's proposal aims to combine the strengths of both string theory and LQG by using string theory's concept of "background independence" and LQG's approach of quantizing space-time into discrete units. This combination could potentially resolve some of the major challenges in both theories and lead to a more comprehensive understanding of quantum gravity.

3. What are the potential implications of Thiemann's proposal?

If successful, Thiemann's proposal could provide a unified framework for understanding the fundamental nature of the universe and potentially lead to new predictions and experimental tests. It could also have significant implications for our understanding of space, time, and the nature of reality.

4. What are some of the criticisms of Thiemann's proposal?

Some critics argue that Thiemann's proposal is still in its early stages and lacks concrete mathematical foundations. Others question whether it is truly a unification of string theory and LQG, as it relies heavily on string theory concepts and may not fully incorporate LQG's principles.

5. What are the next steps for Thiemann's proposal and the field of quantum gravity?

Thiemann's proposal is still being actively researched and refined by physicists. In the broader field of quantum gravity, scientists are continuing to explore various approaches and theories in order to gain a deeper understanding of the fundamental laws of the universe.
