Collapse Models of Quantum Mechanics

In summary, the conversation discusses the potential modification of Quantum Mechanics to allow for physical collapse and the need for the new theory to account for previously verified results while potentially making different predictions in untested areas. One example of disagreement between QM and the new theory is mentioned, and it is suggested that the experimental differences may be found in the macroscopic scale or in untested microscopic processes. The possibility of hidden variables in the new theory is also mentioned. The questioner asks if the person has found any further insight on this topic.

I'm guessing if Quantum Mechanics get modified to allow for physical collapse, the Schrodinger equation is modified. But whatever has already verified Quantum Mechanics thus far, the new theory needs to account for those results but, I would assume, make different predictions in other areas that haven't been tested, in comparison to QM.

What would one example of where QM and the new theories would disagree (apart from the latter including collapse)?

Is the experimental difference between the two inclined to be in the macroscopic scale? Or are there processes in the microscopic world that haven't been tested, where QM and new collapse theories would offer different predictions?

EDIT: I dare say that if QM and the other theories give the same predictions where experimentally verification has been seen, then technically one could allow hidden variables to exist in the new theory. Even if there is no definite prediction for which state actualises in new theories, you could possibly allow one to have hidden variables choosing that result - as is the case in addition to standard QM.

@StevieTNZ did you find any more insight on this topic?
 

1. What is the collapse model of quantum mechanics?

The collapse model of quantum mechanics is a theory that attempts to explain the phenomenon of wavefunction collapse, also known as the measurement problem. It proposes that when a measurement is made on a quantum system, the system's wavefunction collapses to a particular state. This collapse is seen as a fundamental and irreversible process in the universe.

2. How does the collapse model differ from other interpretations of quantum mechanics?

The collapse model differs from other interpretations, such as the Copenhagen interpretation, in that it views wavefunction collapse as a real physical process rather than just a mathematical description. It also suggests that there is no inherent randomness in quantum mechanics, but rather the appearance of randomness is due to our lack of knowledge about the exact state of the system.

3. What evidence supports the collapse model of quantum mechanics?

There is currently no direct evidence that supports the collapse model of quantum mechanics. However, some physicists argue that the model can account for the behavior of quantum systems and make predictions that are consistent with experimental results. Additionally, the collapse model has been used to propose new experiments that could provide evidence for its validity.

4. Are there any criticisms of the collapse model?

Yes, there are several criticisms of the collapse model. One major criticism is that it is not a complete theory and does not provide a clear understanding of how and why collapse occurs. Some also argue that the model violates conservation of energy and momentum, as well as other fundamental laws of physics.

5. How does the collapse model impact our understanding of reality?

The collapse model challenges our traditional understanding of reality, as it suggests that the act of observation or measurement can fundamentally change the state of a system. It also raises questions about the role of consciousness in quantum mechanics, and whether our observations and perceptions play a larger role in shaping reality than previously thought.
