How can it be deduced general relativity from planck length

In summary, the conversation discusses the possibility of deducing general relativity from Planck length, which is an arbitrary length in quantum physics. The question is considered unconventional and unpublished, but there may be a correlation between the correct use of the Heisenberg uncertainty principle and the theory of relativity. Further reading is suggested for a more detailed discussion.

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The question is certainly drastically condensed but it is not meaningless; it is just unconventional and unpublished.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.
 

Related to How can it be deduced general relativity from planck length

1. What is the Planck length?

The Planck length is the shortest possible length in the universe, representing the scale at which classical physics breaks down and quantum effects become important. It is approximately 1.6 x 10^-35 meters.

2. How does general relativity relate to the Planck length?

General relativity is a theory of gravity that describes the curvature of spacetime caused by massive objects. At very small scales, such as the Planck length, the effects of gravity become intertwined with quantum effects, making it necessary to reconcile the two theories.

3. What is the process for deducing general relativity from the Planck length?

The process of deducing general relativity from the Planck length involves using mathematical equations and experimental evidence to understand how gravity behaves at the smallest scales. This includes studying the effects of spacetime curvature and the behavior of particles on the quantum level.

4. What are some key concepts to understand when deducing general relativity from the Planck length?

Some key concepts to understand are the principles of general relativity, including the equivalence principle and the Einstein field equations, as well as the principles of quantum mechanics, such as uncertainty and wave-particle duality. Additionally, an understanding of mathematical concepts such as tensors and differential geometry is necessary.

5. How does the Planck length help us understand the universe?

The Planck length helps us understand the universe by providing a framework for studying the behavior of gravity at extremely small scales. It also allows us to reconcile the theories of general relativity and quantum mechanics, which are both crucial for understanding the workings of the universe on a large and small scale.
