Is Einstein Causality Proven in Preferred Frame SR?

In summary: Moreover, it...No, it doesn't. What distinguishes interpretations is not anything in the math; they all use the same math, what you are calling the "minimal math".If by "fact" you mean "confirmed by experiment", then no, no interpretation of QM is confirmed by experiment. If one were confirmed by experiment, it wouldn't be an interpretation of QM any more, it would be a new theory that replaced the QM we have now.

Oh, for goodness' sake. Bell's paper has mathematical statements in it. Each one has a number. Which number points to a false statement? I fail to see why you can't just answer that question without going off into the vagaries of ordinary language terms like "Einstein causality".
(2) points already to a statement that cannot be proven in SR with a preferred frame. I refer to Einstein causality because I thought a precise answer has to identify the principle which holds in spacetime SR but not in preferred frame SR and to explain why (2) cannot be derived in preferred frame SR. Such an explanation has to compare how (2) is derived for spacetime SR, and to show why it fails in preferred frame SR. This derivation is given in informal, verbal form, so my explanation has an informal, verbal form.

But once you insist, no problem, (2) cannot be proven in preferred frame SR.
 
<H2>1. Is Einstein's theory of causality proven in the preferred frame of special relativity?</H2><p>Yes, Einstein's theory of causality is proven in the preferred frame of special relativity. This theory states that the laws of physics are the same for all observers in uniform motion, regardless of their relative velocity. This means that the concept of causality, which states that an effect cannot occur before its cause, remains consistent in all inertial reference frames.</p><H2>2. How does the preferred frame in special relativity affect causality?</H2><p>The preferred frame in special relativity, also known as the "stationary frame", is the frame of reference in which an observer is at rest or moving at a constant velocity. In this frame, the laws of physics, including the principle of causality, are unchanged. This means that causality remains valid and consistent in all inertial reference frames.</p><H2>3. Can causality be violated in special relativity?</H2><p>No, causality cannot be violated in special relativity. The theory states that the speed of light is the same for all observers, regardless of their relative motion. This means that the concept of causality, which relies on the idea of cause and effect occurring in a specific order, cannot be violated.</p><H2>4. How does the concept of simultaneity relate to causality in special relativity?</H2><p>In special relativity, simultaneity is relative to the observer's frame of reference. This means that two events that appear simultaneous to one observer may not appear simultaneous to another observer in a different frame of reference. However, the principle of causality still holds true in all frames of reference, as cause and effect must occur in a specific order regardless of the perceived simultaneity.</p><H2>5. Is there any experimental evidence supporting the validity of causality in special relativity?</H2><p>Yes, there is significant experimental evidence supporting the validity of causality in special relativity. One example is the famous Michelson-Morley experiment, which showed that the speed of light is constant in all inertial reference frames. This supports the idea that causality remains consistent in all frames of reference, as the speed of light is a fundamental factor in determining the order of cause and effect.</p>

FAQ: Is Einstein Causality Proven in Preferred Frame SR?

1. Is Einstein's theory of causality proven in the preferred frame of special relativity?

Yes, Einstein's theory of causality is proven in the preferred frame of special relativity. This theory states that the laws of physics are the same for all observers in uniform motion, regardless of their relative velocity. This means that the concept of causality, which states that an effect cannot occur before its cause, remains consistent in all inertial reference frames.

2. How does the preferred frame in special relativity affect causality?

The preferred frame in special relativity, also known as the "stationary frame", is the frame of reference in which an observer is at rest or moving at a constant velocity. In this frame, the laws of physics, including the principle of causality, are unchanged. This means that causality remains valid and consistent in all inertial reference frames.

3. Can causality be violated in special relativity?

No, causality cannot be violated in special relativity. The theory states that the speed of light is the same for all observers, regardless of their relative motion. This means that the concept of causality, which relies on the idea of cause and effect occurring in a specific order, cannot be violated.

4. How does the concept of simultaneity relate to causality in special relativity?

In special relativity, simultaneity is relative to the observer's frame of reference. This means that two events that appear simultaneous to one observer may not appear simultaneous to another observer in a different frame of reference. However, the principle of causality still holds true in all frames of reference, as cause and effect must occur in a specific order regardless of the perceived simultaneity.

5. Is there any experimental evidence supporting the validity of causality in special relativity?

Yes, there is significant experimental evidence supporting the validity of causality in special relativity. One example is the famous Michelson-Morley experiment, which showed that the speed of light is constant in all inertial reference frames. This supports the idea that causality remains consistent in all frames of reference, as the speed of light is a fundamental factor in determining the order of cause and effect.
