Discussion Overview

The discussion centers around the relationship between the speed of light, time, and the phenomenon of quantum entanglement, often referred to as "spooky action at a distance." Participants explore whether the concept of time stopping at the speed of light can explain the instantaneous adjustments in the spins of entangled photons.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant suggests that if photons interact, they may continuously affect each other, implying that time does not progress for them at the speed of light.
  • Another participant argues that time does not "move" and that the concept of time is merely a tool to describe the motion of material objects, not an inherent property of the universe.
  • A later reply discusses the Minkowski metric and suggests that as the spatial distance approaches the speed of light, the corresponding time interval approaches zero from the perspective of an observer moving slower than light.
  • One participant challenges the initial claim by stating that the non-locality effect is observed in the lab frame, not in the frame of the photons themselves.
  • A request for clarification is made regarding the specifics of photon spin interactions, including the implications of simultaneous spins and their relation to time.

Areas of Agreement / Disagreement

Participants express differing views on the nature of time and its relationship to the behavior of photons, with no consensus reached on the explanations or implications of these phenomena.

Contextual Notes

Some assumptions about the nature of time and motion are not fully explored, and the discussion includes various interpretations of quantum mechanics and relativity without resolving the underlying complexities.

Does time "stopping" at c explain spooky action at a distance?

My thinking is this:
We know that two interacting photons will adjust their spins relative to each other.
We know that if one of these photons change their spin at some time in the 'future', the other photon will instantaneously adjust it's spin relative to the original photon.
Since photons travel at c, at which speed time doesn't 'move', isn't is possible that the two photons are effectively still interacting or continuously interacting with each other?

Opinion: time does not "move" in the first place. Material objects in a real universe move and in order to describe the movement we need the concept of time.
When time "stops"...it is not being stopped by anything..what you are effectively saying is that "point" where there is no motion in the universe.
What about light waves themselves? Their motion is unique in the universe..their speed is not relative to anything...as are material objects in the universe that produce events in our universe.
Note: photons could have a "pre-ordained" relationship to each other...the future "entanglement" could be the result of a former relationship.

I think he means to say that in the Minowski metric equation

c2dT2=c2dt2+dx2 , where dx2 is in the direction of motion,

as dx2->c2dT2, dt2->0 , so any amount of proper time corresponds to zero coordinate time, seem from an observer moving slower than c.

No. The experiment is done in lab frame, and it is in this frame that we detect the non-locality effect, NOT in the photon's frame.

Can you explain this phenomena in detail please? It may help others who read this thread and it would seem that it greatly applies to the work I'm doing. You say that one photon will spin in relation to another, at what distance is this observed? And what do you mean by a future spin, if they spin up at the same time does that imply any effect on time or affected by time?
