Discussion Overview

The discussion revolves around the comparison of the speed of gravity and quantum entanglement, often referred to as "spooky action at a distance." Participants propose experiments to test the instantaneous nature of both phenomena and explore the implications of their findings.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant proposes an experiment to test whether both gravity and "spooky action" are instantaneous, drawing an analogy to the speed of sound versus light.
  • Another participant argues that "spooky action" has no speed, as it only becomes apparent after remote measurements are compared, suggesting that information travels at the speed of light.
  • A different participant asserts that "spooky action" is indeed instantaneous and conjectures that the speed limit of symmetric change is also instantaneous, questioning whether the warping of space due to matter is instantaneous as well.
  • Another participant challenges the notion of discussing the speed of "spooky action," emphasizing that it does not make sense to attribute a speed to it and reiterates the conjecture about symmetric change.
  • There is a query regarding the existence of scientific experiments that test the instantaneous nature of gravity and quantum entanglement.

Areas of Agreement / Disagreement

Participants express differing views on whether "spooky action" can be considered instantaneous and whether it is meaningful to discuss its speed. The discussion remains unresolved, with multiple competing perspectives on the nature of these phenomena.

Contextual Notes

Participants note the limitations of their conjectures and the need for scientific experiments to validate their claims. There is ambiguity regarding the definitions of terms like "expose matter to space."

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.
