Thank you both for your replies. I think I now have a clearer idea of where my thinking was flawed.

Sorry, I’ll try again. I suppose another way of putting it is that in the distant past everything was condensed into such a small area that every event was causally relevant to every other event (at least that’s what I assume, perhaps erroneously). This is no longer the case because every event...

I’m getting confused somewhere, and I’d be obliged if someone could pinpoint my error. 1. At or near the Big Bang, everything was so close as to be within each other’s light cones. 2. All parts of the cosmos are now outside of some other parts’ light cones. Therefore, 3. Something traveled...

Well, if there‘s a ‘way the world works’ and I’m part of the world, presumably the world will be picking an interpretation for me anyway, so I don’t need to bother.

Thanks, DrChinese. That makes things clearer. My mistake was equating ‘properties’ with ‘definite values’. Interaction requires the former but not the latter.

How can a quantum object interact with its environment before it has any definite properties? It seems like a ‘chicken and egg’ scenario to me. I can’t see how anything could interact with a quantum object which has only potential properties (what is there to interact with?), yet if I’ve...

Thank you all for your replies. It’s much appreciated.

If quantum objects’ superpositions decohere rapidly due to exposure to a surrounding environment, why have I heard it said that two entangled particles can be a large distance apart while still having undetermined properties? Wouldn’t decoherence occur while the particles were moving apart?
