I'm going to have to think on this more but it seems highly non-trivial to me to even count the number of fields.

Up, down, strange, charm, top, bottom. Yes, that counting leaves out the quarks' color charge. But note that, for example, when we say...

Pretty good starting point, but let's make things a bit sharper. Consider 1. Is it possible to do what you say for any two events...

What is the reason to count only 6 quarks? We count only the doublet from the weak SU(2) interaction and not the triplet from the strong...

Maybe we can try another way. Can you say in your own words, without quoting, what "relativity of simultaneity" means? It seems to me...

6 leptons, 6 quarks, 12 gauge bosons, and the Higgs in the Standard Model. Of course this counting leaves out a lot of things. Hobson...

I wonder how he counts 25.

These are not the same moment, there is no universal same moment. That is exactly the point of the relativity of simultaneity. Please...

Let's try to get clear on what's going on. It's super easy to get a lot of misconceptions and it all has to do with lack of verbal...

Additional to @Dale's comments, you also assume that they zeroed their clocks when they passed one another. And you are talking about...

So to answer the top level question, yes measurements will affect ##\langle A\rangle## because they affect ##| \psi\rangle## and...

Others have discussed some practical issues with doing this experiment but if we ignore those, we can analyze this experiment based on...

This is a very long question which covers quite a bit of the QFT machinery. It might be more productive to focus on one specific...

They earn their name "ghost particle" :)

You're right, my fault. And from your formula ##\sigma \propto G_F^2 E_\nu^2##, slow neutrinos would be even harder to detect, making...
