I mean that the uncertainty in complementary variables such as position and momentum exists with or without the act of observation, or measurement. We can certainly observe it in an artificial setting, but it’s also the reason that the sun “burns” nuclear fuel the way it does.
- wadkar 9y agoWow, that sounds very profound - whether we observe (measure?) or not the uncertainty will be there. I must admit I couldn’t understand the connection with the sun burning up the fuel. Perhaps you could elaborate on it a bit more?
- QAPereo 9y agoHappily! The sun lacks the necessary mass to burn using the nuclear reaction it uses (CNO), and quantum tunneling is the answer to how it burns.
