It isn't that what is there isn't true until you observe it. It is that you must observe it to know what state it is in.

True quantum physics just make predictions that are much broader than yes or no.

On large scales, I can throw a baseball and there is a 99.99999~% chance that it will end up in the direction I throw it.

In the quantum world, if throw a particle in one direction, it has a x chance of going here, and y chance of ending up over here, or z chance of being somewhere else.

Then you pick the highest number and hope that's where is goes.

Except... it may end up in both places or nowhere near where I was looking for it.
