What is the hardest question to ask a quantum physicist?

[pst007x]

This may be just my mis-understanding, but... If at one time all particles were entangled, at the point of origin, why not now?

"Which interpretation of QM is the correct one?"

All of them, and none of them.

I am curious about this one as well!

I once posted this question to a physics group and the unanimous reply was that everything IS entangled. This entangling is so complicated that it is unpredictable, random, of no use, so it is of no practical importance.

You could ask him how he's doing. Does he want a drink...and hows the Kids...You did say he was a Freind!

"What's the hardest question I could ask you about quantum physics?"

Nyuck nyuck nyuck.

I was just browsing the internet trying to learn new things like most not normal teenage kids that happen to be nerds. When I came upon this question.

"If no one looks is the moon really there"

I kinda laughed because this is one of those deep physiological questions that only dumbos ask.

Other questions that idiots ask are "If a tree falls and know one is there to hear it, does it make a sound" and "What came first? The chicken or the egg?" It is the egg obviously. This moon question struck me as even dumber than the chicken one though, so I felt compelled to make an account to rant and rage at the guy asking this question. First of all it is very unlikely that everyone in the world will just one day happen to not look at the moon at the same time. That is beside the point but still... If everyone was to not look at the moon at the same time it would still exist. If the moon does not exist and or never did exist we would not exist either, because the moon makes these things called tides and these things called tides control the currents in the ocean which in turn control the movement of hot and cold water. This hot and cold water controls the temperature of the air above it which creates air currents in the sky known as "Wind". This can create big storms which control what goes on in our lives. You may think that the weather is not very important but in all honesty we would not be alive without these tides because tides have existed since the first oceans began to form. Even if these oceanic tides did not affect our weather we still need to keep in mind that the moon also creates a tide in our Earth's crust. Each night the crust of the Earth actually bulges out about 12 to 18 inches creating mass amounts of friction that help to heat the mantle below us. Without these crust tides Earth may have frozen solid millions of years ago just like mars. So in much simpler words we all know that the moon exists even when we are not looking at it because we are here and breathing.

I'm going to have to agree with some above that the premise of "being able to answer any question" about QM is not totally far fetched... in the sense that it does present a self defined internally complete and consistent system... kind of in the way that a swimmer can cross a river without having to touch bottom (because he knows how to swim).

Maybe try a more direct challenge at a more fundamental level:

Ask him to write down a random number, then demonstrate that the number is random.

Follow-up question: If picking a random natural number, mustn't that number be infinite?

...I promise to post his answers up on this blog for you to see what he comes back with.

We never heard back from realblonde... And I would like to know so many things!
