How can it be deduced general relativity from planck length

Click For Summary
SUMMARY

The discussion centers on the question of deducing general relativity (GR) from the Planck length. Participants clarify that the Planck length is an arbitrary measurement, similar to other units of length, and emphasize the need for a more precise formulation of the question. The conversation references the paper "On gravity and the uncertainty principle" (arxiv:gr-qc/9904026v2) to highlight the relationship between Heisenberg's uncertainty principle and general relativity. The consensus is that while the question is unconventional, it is not without merit and requires further exploration.

PREREQUISITES
  • Understanding of general relativity concepts
  • Familiarity with Planck length and its significance in physics
  • Knowledge of quantum mechanics, specifically Heisenberg's uncertainty principle
  • Ability to interpret academic papers in theoretical physics
NEXT STEPS
  • Read the paper "On gravity and the uncertainty principle" (arxiv:gr-qc/9904026v2)
  • Explore the implications of Planck scale physics on classical theories
  • Investigate the relationship between quantum mechanics and general relativity
  • Study advanced topics in theoretical physics, such as quantum gravity
USEFUL FOR

Physicists, researchers in theoretical physics, and students interested in the intersection of quantum mechanics and general relativity.

Question doesn't make sense. Plank length is just an arbitrary length. That's like asking how can we deduce GR from the meter or the foot or the mile.
 
Do you mean how can the classical theory of general relativity be deduced from quantum Plank scale physics?
 
The question is certainly drastically condensed but it is not meaningless; it is just unconventional and unpublished.

Can you then restate it so it makes sense and is meaningful?

Blackforest has PM'd me indicating that his answer would not be within the forum rules so I still have no information that would lead me to believe that the OP's question makes any sense. Garrolu, can you clarify your question?

In some way parented with your approximate formulation you may eventually appreciate the discussion exposed here:
[arxiv:gr-qc/9904026v2, 14 April 1999] "On gravity and the uncertainty principle".
I hope you enjoy it and perceive the strong logical correlation between the correct utilization of the Heisenberg's uncertainty principle and the possibility to get a connection with the theory of relativity.
