How could quantum effects occur in the early universe without an observer?












2














In inflanatory cosmology, primordial quantum fluctuations in the process of inflation are considered responsible for the asymmetry and lumpiness of the universe that was shaped. However, according to the Copenhagen interpretation, any random quantum phenomenon only occurs when the system is observed; before observation, the quantum state is symmetric. So the question is, who has observed the universe while inflating? Obviously, there has been no conscious creature that time.



Actually, this problem is discussed in the paper below, and the proposed solution to the problem in said to be an observer-independent interpretation (the pilot-wave theory).

The Copenhagen interpretation isn't an essential part of quantum mechanics. It isn't required in order to make physical processes happen. It's just a way of describing what seems to happen when an observer makes a measurement. It's not even the only way of describing what it seems like to the observer.




However, according to the Copenhagen interpretation, any random quantum phenomenon only occurs when the system is observed; [...]




If you don't use the Copenhagen interpretation, quantum mechanics still works fine. In your example of the early universe, all the quantum-mechanical processes work in the same way. E.g., a hydrogen atom in an $n=3$ state will radiate light, and at a later time it will be in a superposition of $n=2$ and $n=1$. No randomness, just a superposition.




[...] before observation, the quantum state is symmetric.




I'm not sure what you mean by symmetric here. This seems like a nonstandard description.

  • You say there has been a "superposition" of all possible outcomes in the inflation, so what has destroyed the superposition? In Copenhagen, ONLY observation can collapse the superposition. If you believe it has automatically collapsed, you are defending "objective collapse" interpretations, and another option is that the universe is still in superposition (the many worlds interpretation). Either way you are implying one of these two kinds of interpretations, aren't you?

“Observe” oftentimes causes a lot of confusion for this exact reason. It doesn’t actually refer to some conscious entity making an observation.



Rather, think about how we actually make an observation about something. You have to interact with the system in some way. This can be through the exchange of photons, for example. This interaction is what constitutes an observation having taken place.



Obviously, particles can undergo their fundamental interactions without a nearby sentient entity.
