Mariner forgot to include his own example of quantum physics versus Einsteinian physics, which he believes describes more clearly the difference in definition between the two than Schrodinger’s cat:
You are driving on an interstate highway. The highway is not busy. For the moment, you are the only car you see on the entire visible highway – in front or in back and none on the other side.
Question one: At the moment, are you the fastest car or the slowest? Yes.
Finally, a car appears down the road in front of you. Are you fastest or slowest?
Second question: About this sudden event where a car becomes part of your reality, it appeared on your highway as a definable car, at the same clock time and the same measurable distance (Einstein).
However, Quantum says, “No, not so fast”. The car just didn’t assemble itself out of nothing the moment you saw it; what events caused the car to appear at that moment?
For example, did the car turn on the highway just over the hill or has it been on the road for two days coming from New Jersey? How did the driver come to be in the car at that moment? Why is it a Subaru? Why is it on that highway? What time did it depart so that you would experience it at that moment?
Quantum’s point being that nothing exists in an absolute state, in a precisely definable moment or at an absolute distance. In other words, mass, time, and space are not finite.
The closest human realization that mariner can conjure is when you suddenly meet an old friend at a surprising place. You say “Can you imagine the odds of us meeting?” Quantum can.
