If you are the experimenter what can physics tell you about the particle's half 
life?  It is not implied by the laws of physics because there are many laws of 
physics.  Until the experiment is performed, even the laws of physics are not 
in stone.  This is a main point of Bruno's result: physics is not at the bottom 
of the explanatory ladder, the laws of physics depend on the distribution of 
observers similar to your current state of mind throughout its infinite 
manifestations in reality.

Physics is at the bottom of all non-mathematical things that have an 
explanation, but we now know that some things have no explanation. We now know 
that some things are random.


Here you accept there is inherent randomness.

Where do you think this randomness comes from?

Do you think it is an objective feature of reality or only an illusion
for observers?

I don't see this at all. After the duplication all the John Clark realise that 
they are in only one city, and that they were unable to predict which one. So 
both of them understand that this peculiar experience was not predicable.

Wrong! John Clark correctly predicted that the Moscow man would see Moscow and 
the Washington man would see Moscow. John Clark doesn't understand what more 
should be expected of a prediction;
If you have ever played a game like poker, you would see predictions
all the time of the form: there is X% chance you experience winning
the the pot and (1-X)% chance you experience losing or sharing the
pot.  You won't play the game very well if you operate under the
theory that there is a 100% chance that you will experience winning,
losing, and sharing the pot (as some of your duplicates in the
multiverse inevitably do).
But it's hard to see what 1/pi of a duplicate would be.
