String Theory & LQG: Explaining Particles & Forces

AI Thread Summary
String theory posits that all particles and forces are manifestations of vibrating strings, while Loop Quantum Gravity (LQG) seeks to provide an alternative framework for understanding particles. There is speculation that in LQG, quarks may correspond to the intersections of a lattice, although specific references are unclear. Current discussions highlight that LQG's approach to incorporating other particles beyond gravity remains vague and problematic. Notably, calculations related to black hole entropy in LQG suggest limited capacity for accommodating additional particles. Overall, the exploration of LQG as a comprehensive theory is still in its early stages.

In string theory, all particles and forces of nature of mere results of vibrating strings. Can LQG offer an alternative explanation for the zoo of particles we find? I seem to recall reading that the theory proposes that quarks are where edges of the lattice intersect, but I can't recall where. Is this correct, and has any progress been made in explaining the source of the forces?

Ideas about how to move beyond pure gravity LQG are vague. The most natural (vague) idea is problematic: LQG black hole entropy calculations appear to indicate insufficient room in LQG for any other particles.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
