Backward causation intepretation

[michael879]

can someone explain this interpretation to me? I read the article
**************** (my post got deleted for posting a non peer-reviewed article?)
but they only seem to discuss this interpretation with respect to entanglement. Other than that one case, it appears to be identical to the Copenhagen interpretation (i.e. single particles are still described by probability waves and the measurement made on one of the entangled particles is still completely random).

Is there any more detailed source on this interpretation?

The interpretation you are referring to is called the Many Worlds Interpretation (MWI). It was first proposed by physicist Hugh Everett III in 1957 and has since been the subject of much debate. The core idea behind the MWI is that when a quantum measurement is made, the universe splits into multiple universes, each containing one of the possible outcomes of the measurement. In other words, the wavefunction does not collapse, but instead each potential outcome is realized in a separate universe. This means that all superposition states exist simultaneously, which is different from the Copenhagen interpretation which states that the wavefunction collapses when a measurement is made. For more information on the Many Worlds Interpretation, there are numerous online sources discussing the details of the interpretation. You can also read Everett's original paper, titled "Relative State Formulation of Quantum Mechanics," for a more detailed understanding.

I can provide an explanation of the backward causation interpretation, also known as retrocausality. This interpretation suggests that future events can influence past events, contrary to the traditional understanding of causation where cause precedes effect. This idea challenges the concept of time as a linear progression and suggests that the future and the past may be interconnected.

This interpretation has been discussed in the context of quantum mechanics, particularly with regards to the phenomenon of entanglement. In entanglement, two particles can become correlated in such a way that the state of one particle is dependent on the state of the other, even if they are separated by large distances. In the backward causation interpretation, this correlation is seen as evidence that the future state of one particle can influence the past state of the other particle.

However, as you mentioned, there is not a lot of detailed information on this interpretation outside of the context of entanglement. This is because it is still a controversial and speculative idea within the scientific community. While some physicists have explored the possibility of backward causation in quantum mechanics, there is not yet a widely accepted theory or explanation for how it could work.

In general, the backward causation interpretation is not widely accepted in the scientific community due to the lack of empirical evidence and the challenges it poses to our current understanding of causality and time. But as with any scientific idea, it is important to continue exploring and considering different interpretations in order to further our understanding of the universe.
