What is faster, Gravity or "Spooky Action" at a distance?

In summary, the conversation discusses the possibility of conducting an experiment that simultaneously tests the concepts of matter warping space (gravity) and quantum entanglement. It is questioned whether the result of this experiment will show that both changes are instantaneous or if it will be similar to the old experiment of the race between light and sound, where light is much faster than sound. The concept of "spooky action" is also discussed, which is said to have no speed and only appears after two remote measurements are compared. It is suggested that this may be a symmetric change with an instantaneous speed limit. However, the idea of discussing personal theories is not allowed and the conversation is closed.

Propose an experiment:

Simultaneous test of matter warping space (Gravity) and quantum entanglement "spooky action" at a distance where the spin of the other particle instantly changes to clock or counter clock.

Will the result be that both Symmetric Changes are instantaneous?

Or will it be like the old experiment in the race between light and sound. Where from a distance we can see the hammer striking the metal fence pole a few seconds before we hear the corresponding sound?

In other words, light is much faster than sound.

Is "spooky action" faster than gravity or vice versa.

"Spooky action" has no speed. It only appears after two remote measurements are compared. At best, that information travels at the speed of light.

You are right spooky action is instantaneous. It doesn't just appear. It is my conjecture that it is symmetric change. Speed limit of Symmetric Change is instantaneous. We cannot observe it. We can only observe the end result (the change in spin)

But, is the warping of space when exposed to matter also instantaneous?

Are there any scientific experiments testing these results?

I never said that. What I said means that it does not make sense to discuss the speed of "spooky action at a distance."

We do not discuss personal theories at PF. (*)

What does it mean to expose matter to space? Wasn't that matter already somewhere?

(*) therefore I am closing this thread.
 

FAQ: What is faster, Gravity or "Spooky Action" at a distance?

1. What is the difference between Gravity and "Spooky Action" at a distance?

Gravity is a fundamental force of nature that describes the attraction between two objects with mass. "Spooky Action" at a distance, also known as quantum entanglement, is a phenomenon in quantum mechanics where two particles become connected and can affect each other's properties even when separated by large distances.

2. Which is faster, Gravity or "Spooky Action" at a distance?

According to the theory of general relativity, gravity propagates at the speed of light. On the other hand, "Spooky Action" at a distance has been observed to occur instantaneously, regardless of the distance between the entangled particles. However, this does not violate the speed of light limit because no information is actually being transferred.

3. Can "Spooky Action" at a distance be used for faster-than-light communication?

No, "Spooky Action" at a distance cannot be used for faster-than-light communication. While the phenomenon may seem instantaneous, it does not violate the speed of light limit as no information is being transferred. It is also not possible to control which properties of the entangled particles will be affected, making it impossible to use for communication purposes.

4. How does "Spooky Action" at a distance relate to Einstein's theory of relativity?

"Spooky Action" at a distance is a phenomenon that occurs at the quantum level, while Einstein's theory of relativity describes the behavior of objects at the macroscopic level. While quantum mechanics and general relativity are both successful theories, they are not yet fully compatible with each other. The phenomenon of quantum entanglement challenges our understanding of space and time in the context of relativity.

5. Is there any practical application for "Spooky Action" at a distance?

While "Spooky Action" at a distance is still not fully understood, it has been demonstrated to have practical applications in quantum computing and cryptography. Entangled particles can be used to create quantum gates, which are essential for quantum computers. It also allows for secure communication, as any attempt to intercept the information would disrupt the entanglement and be noticed by the receiver.
