This is a testable prediction.

Correct. No empty bags. No mixed bags. All coins in each bag are either real or fake.

There are 5 bags full of coins which look identical, but all the coins in some bags are real while all the coins in other bags are fake. Real coin weighs 10 g, fake coin weighs 9 g. Using a weighing scale, identify the bags with real and the bags with fake coins by weighing only once. PS. It is also possible that coins in all the bags are real, and that coins in all the bags are fake.

There are places with such names in PA, e.g.,

I don't think so. Such response requires more than written and spoken material for the foundation. If it is a language model, I don't think this will ever happen.

It is a frame in which expectation value of the electron momentum vanishes.

100 km on its odometer, three times. Each leg's length is 100 km.

On p.1, E=hc/λ is, presumably, energy of a photon. Two lines below, E=mc2 is not energy of a photon. These two E's are not the same thing.

More rigorously,

Mars rover made 100 km South, then 100 km West, and then 100 km North, arriving to the starting point. What was the starting point? This puzzle is easy, but not too easy.

@md65536 Hint:

Yes, you are right (I know how you did it ).

The answer is right, and it is a very good heuristic, but it is not rigorous. It doesn't happen to be so in general - it works here because we assume that the answer is completely determined by the given data. +1

Yes, it is. +1

Let's reformulate the question then: To what extent can a computer program approximately simulate QM behavior of electron? Which aspects of it cannot be simulated in principle?

Yes, here it is: This is snapshot from about minute 35 of this lecture: Lecture 23: Inflation | The Early Universe | Physics | MIT OpenCourseWare. At about minute 50+ he gives the numerical estimate for the parameters. I think that in this lecture Guth answers most or all of the questions you've asked about inflation (including, "Here is where inflation stops, and the conventional big bang begins.") Highly recommend.

Re reason 1. A simulation could use numerical methods and calculate with precision according to a measuring instrument. Re reason 2. Wave function provides a full QM description. The simulation could calculate eigenvalues with the associated probabilities and output an answer accordingly. Wouldn't the above solve these two issues?

I think that Bell theorem answers this question negatively.
