Thought experiment
If you have a person A in London and a person B in New York and A sends B an email. At this point A doesn't know whether B got the email, so to clarify matters B sends back a confirmation email saying that he got the email.

At this point A knows that B got the email, B knows he got the email but B doesn't know whether A knows that he got the confirmation email.

So to clarify the matter A sends back an email stating that he received the confirmation email.

But then A doesn't know whether B got this email!!!!!!!....

so on and so on......

end of thought experiment.


Is this an important dilemma in the logic of communications?
Does it have a name?

If the same logic where to apply to the information exchange within atoms and within subatomic particles(the information that keeps a particle running, ie the blueprint of the particle, the information that keeps the particle in one piece), would this explain why entangled particles are closed systems?
