I'm learning quantum mechanics and there's one thing I don't understand. I hope Veeky Forums can help me.

tl;dr: What exactly is causing the collapse of the wave function?

In my uderstanding there are all kinds of interactions. When two or more particles interact, their wave functions become somehow related but still remain uncollapsed. But a "measurement" instantaneously projects the wave function in some eigenspace. I guess my question can be rephrased: Which kinds of interactions constitute "measurements" and which don't? For what reason?

Have you tried resetting the router?

measuring=transferring the information

>What exactly is causing the collapse of the wave function?

Nobody knows. You take a measurement and then wave function collapses to a definite state, what causes that to happen, no one knows.

There is no such thing as wave function collapse

Wave function is a probability density (well not quite). When you measure the coin must be either heads or tails.

Actually it depends on interpretation, however the many world's interpretations is more plausible than the copenhagen

No collapse just interactions

How so?
