Quantum Gravity Technology Spinoffs?

Click For Summary
SUMMARY

The discussion centers on the implications of solving quantum gravity, specifically whether it will lead to new technologies or merely enhance our understanding of interactions at the Planck scale. Participants highlight the necessity of new technology to gather experimental evidence for quantum gravity. Peterdonis clarifies the concept of "low energy approximation," explaining that at low average energy per particle, the observable physics is limited to general relativity (GR) rather than quantum gravity. The conversation also explores potential low-energy signatures of quantum gravity that could be detected.

PREREQUISITES
  • Understanding of quantum gravity concepts

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?

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...).
