An approximation for "observation".

so your saying something does not exist until we see it?
i read that virtual particle's are never physically real and that they are a methaphor?
am i going to be ignored now is that it?
so nobody on here can hear anymore? you guy's "too busy"?
Maybe you could have a look at the information angle.
What happens to a particle's information content in a qubit, when you perturb or measure it. Information is causal, right?
By which I mean it isn't created out of thin air.
Otherwise lack of responses should be a clue that asking the same question as you asked a couple of months back isn't going to fly. You will have to read something all by yourself (not that tricky these days).
isn't everything causal anyway's?
You should see if you can find out what "expectation" means, old son.
It's important to the notion of a cause-effect relation, and to the notion of communication.
And your persona seems to have an expectation that's just a little naive, wrt questions you ask (through it).
Luckily I have several personas to choose from (but lets not go there).
ben told me that virtual particle's do violate causality,so they arrive before they leave or go back in time to a time before now?
If you think going back over the same points, then going back over them again, then indicating that you think you should look at them again, is the algorithm you should use, here's a hint for you: it ISN'T.
What did that textbook about information theory tell you? The one you're going to read?
what are you talking about?
What indeed (he he)
are you trying to be sarcastic?
I don't have to, it just comes naturally.
If cause-effect is violated, then you should already know what's in that textbook you haven't read yet.
oh i see so everything in the universe is causal.even VP's
the only causality i know of is cause and effect relation. i drop an egg then it's effect is it break's. but i keep getting messages that there are different kind's of causality's
There is just 1 "kind" of cause-and-effect. Because there is 1 kind of expectation. Our brains measure different "things", but the same way.
do virtual particle's have some sort of time travel attributes since they disapper in an instant or is something else going on?
No, they don't ever 'appear', to start with.
Are you going to find out about Planck's constant - how it was uncovered, what it means, that stuff?
is wiki pretty accurate on planck's constant? i know virtual particle's only appear for like 1 millionth of a second.
