Ok thanks. It seems that the superposition is not a static thing, but evolves with time as the separate states would.

Agree re eternal life. I am just not sure how the cat can age unless it exists in a alive state it's whole time in the box, rather than the neither alive nor dead state that I thought was the case. Probably a simple answer but seems to be escaping me.

Considering only the Copenhagen interpretation, discounting the cat as an observer, and assuming wave function collapse at the time of opening the box - if you find the cat alive, has it aged whilst in the box? Thanks.

Thanks guys, very helpful and much appreciated.

That does seem a good example. Though I have to say when I have been pondering the issue I focused mainly on solids vs liquids because I need to refresh my understanding of how gases behave because there is something here which puzzles me and probably shouldn't. Namely if I allow a gas to expand...

This is a restatement of a question I have been pondering whilst helping my daughter with GCSE physics. My previous post didn't get me the closure I was after so am trying again. I have three different GCSE textbooks. All three have a simple section on the kinetic theory of particles in...

Yes, I admit I kept away from gases in my examples because solids and liquids seemed to have more in common in his context. Having said that I suppose I had assumed the energy in question would be solely kinetic in nature but I have no basis for this other than the point arises in the GCSE...

This came up whilst helping my kid with her GCSE physics so ought to be pretty straightforward. Here goes: At his level the kinetic theory of matter is taught in a simple way and one "key point" which is stated time and time again is "the particles in a gas have more energy than the particles...

Thank you all. Very clear and very helpful. A simple seeming question but one that was making it difficult for me to put other stuff I had been reading, and trying to understand, into context. There is so much detailed discussion and speculation going on in this area that I had been finding...

Simple "Beginner" Dark Matter Question Ok, for some reason I can't seem to get this straight, probably because its so obvious nobody spells it out. Its more a question of terminology than the real mystery of dark matter, but its proving an obstacle in my efforts to catch up on a subject i have...
