Hi guys, I'm a newbie in this area of physics and like many other unfamiliar territories, I've had anxiety and confusion when I first heard the intriguing concepts of this theory. I hope someone can help me understand it better though it is evident that it's very difficult and counter-intuitive. 1) Do objects and particles exist even when they are not measured, just in an undefined state? 2)If small particles can be almost everywhere according to their probability function, how come the objects on the macro level seem fixed, with a pretty defined position (for instance we can calculate how far away from the Earth is the moon etc.) 3)Does QM obey the laws of causality and is it consistent with SR and GR? 4)Long story short, can somebody illustrate to me the basic principles of QM and how they correlate to everyday world and objects that we see, and how the apparent stability of macroobjects can emerge from 'chaos' of electrons etc. Regards.
