When we finally solved for quantum gravity. Would it only give us a solution to understanding the interaction in Planck scale quantum and spacetime or would it also give us new technology?
 
Physics news on Phys.org
I don't know whether theoretical quantum gravity will give us a new technology, but we shall certainly need new technology to find experimental evidence for quantum gravity.

In the thread "Comeback City" asked "Could you explain what you mean by "low energy approximation"?"

And Peterdonis answered: "It means roughly that, if the average energy per particle is low enough, the physics that is present in the underlying theory (quantum gravity in this case) happens too rarely to observe, and the effective physics is limited to that in the approximate theory (GR in this case)."

Can anyone give an example of what "physics" of quantum gravity can bleed thru to be observed at lower energy? I thought it only occur at highest energy in the Planck scale.. what can bleed thru to low energy? What signatures for example have physicists expecting or are looking?

(And it's possible technology spinoff doesn't have to be Planck scale technology.. but one that is the lower energy correlate of quantum gravity...).
 
Thread 'LQG Legend Writes Paper Claiming GR Explains Dark Matter Phenomena'
A new group of investigators are attempting something similar to Deur's work, which seeks to explain dark matter phenomena with general relativity corrections to Newtonian gravity is systems like galaxies. Deur's most similar publication to this one along these lines was: One thing that makes this new paper notable is that the corresponding author is Giorgio Immirzi, the person after whom the somewhat mysterious Immirzi parameter of Loop Quantum Gravity is named. I will be reviewing the...
I seem to notice a buildup of papers like this: Detecting single gravitons with quantum sensing. (OK, old one.) Toward graviton detection via photon-graviton quantum state conversion Is this akin to “we’re soon gonna put string theory to the test”, or are these legit? Mind, I’m not expecting anyone to read the papers and explain them to me, but if one of you educated people already have an opinion I’d like to hear it. If not please ignore me. EDIT: I strongly suspect it’s bunk but...
